Velocity與Jsp、Freemarker的對比javascript

在java領域，表現層技術主要有三種：jsp、freemarker、velocity。macro能夠用於實現自定義指令,經過使用自定義指令,能夠將一段模板片斷定義成一個用戶指令,使用macro指令的語法格式以下:
< #macro name param1 param2 ... paramN> php

<#compress>
...
< /#compress>
用來壓縮空白空間和空白的行css

<#macro path>html

<#compress>java

${request.contextPath}node

</#compress>mysql

</#macro>linux

在引用時是<@path/>android

<#compress>web

var path_="<@path/>";

var user = "${(visitor.name)!''}";

</script>

</#compress>

</#macro>

<#macro Select id name optList optValue showAll=false>

<#if showAll>

所有

</option>

</#if>

<#list optList as opt>

<option value="${(opt.id)!}"

<#if (optValue==opt.id)>selected</#if>

${(opt.name)!}

</option>

</#list>

</select>

</#macro>

<#macro FormSelect id name optType optValue showAll=false>

<#list DtCache?keys as key>

<#if key==optType>

<#assign optList=DtCache[key] >

<@Select id name optList optValue showAll />

</#if>

</#list>

</#macro>

<@Select id="companyName" name="companyName" optList=companyList optValue="" showAll=true/>

<@FormSelect id="devType" name="devType" optType="DevType" optValue="" showAll=true />

　　設置爲float的div在ie下設置的margin會加倍。這是一個ie6都存在的bug。解決方案是在這個div裏面加上display:inline;

#imfloat{
　　float:left;
　　margin:5px;
　　display:inline;}

clear{ clear:both;}

高度不能自適應是當內層對象的高度發生變化時外層高度不能自動進行調節，特別是當內層對象使用margin 或paddign 時。

　　例：

　　#box {background-color:#eee; }
　　#box p {margin-top: 20px;margin-bottom: 20px; text-align:center; }
　　<div id="box">
　　<p>p對象中的內容＜/p>
　　</div>

　　解決技巧：在P對象上下各加2個空的div對象CSS代碼：.1{height:0px;overflow:hidden;}或者爲DIV加上border屬性。

Handler消息傳遞機制淺析

不少時候咱們作界面刷新都須要經過Handler來通知UI組件更新！

1.學習路線圖：

2.Handler類的引入:

3.Handler的執行流程圖：

流程圖解析: 相關名詞

· UI線程:就是咱們的主線程,系統在建立UI線程的時候會初始化一個Looper對象,同時也會建立一個與其關聯的MessageQueue;

· Handler:做用就是發送與處理信息,若是但願Handler正常工做,在當前線程中要有一個Looper對象

· Message:Handler接收與處理的消息對象

· MessageQueue:消息隊列,先進先出管理Message,在初始化Looper對象時會建立一個與之關聯的MessageQueue;

· Looper:每一個線程只可以有一個Looper,管理MessageQueue,不斷地從中取出Message分發給對應的Handler處理！

當咱們的子線程想修改Activity中的UI組件時,咱們能夠新建一個Handler對象,經過這個對象向主線程發送信息;而咱們發送的信息會先到主線程的MessageQueue進行等待,由Looper按先入先出順序取出,再根據message對象的what屬性分發給對應的Handler進行處理！

Handler寫在主線程中

MainActivity.java：

public class MainActivity extends Activity { //定義切換的圖片的數組id int imgids[] = new int[]{ R.drawable.s_1, R.drawable.s_2,R.drawable.s_3, R.drawable.s_4,R.drawable.s_5,R.drawable.s_6, R.drawable.s_7,R.drawable.s_8 }; int imgstart = 0; final Handler myHandler = new Handler() { @Override //重寫handleMessage方法,根據msg中what的值判斷是否執行後續操做 public void handleMessage(Message msg) { if(msg.what == 0x123) { imgchange.setImageResource(imgids[imgstart++ % 8]); } } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final ImageView imgchange = (ImageView) findViewById(R.id.imgchange); //使用定時器,每隔200毫秒讓handler發送一個空信息 new Timer().schedule(new TimerTask() { @Override public void run() { myHandler.sendEmptyMessage(0x123); } }, 0,200); } }

Handler寫在子線程中

若是是Handler寫在了子線程中的話,咱們就須要本身建立一個Looper對象了!建立的流程以下:

1 )直接調用Looper.prepare()方法便可爲當前線程建立Looper對象,而它的構造器會建立配套的MessageQueue; 2 )建立Handler對象,重寫handleMessage( )方法就能夠處理來自於其餘線程的信息了! 3 )調用Looper.loop()方法啓動Looper

使用示例：輸入一個數，計算後經過Toast輸出在這個範圍內的全部質數

實現代碼： main.xml：

MainActivity.java:

public class CalPrime extends Activity { static final String UPPER_NUM = "upper"; EditText etNum; CalThread calThread; // 定義一個線程類 class CalThread extends Thread { public Handler mHandler; public void run() { Looper.prepare(); mHandler = new Handler() { // 定義處理消息的方法 @Override public void handleMessage(Message msg) { if(msg.what == 0x123) { int upper = msg.getData().getInt(UPPER_NUM); List<Integer> nums = new ArrayList<Integer>(); // 計算從2開始、到upper的全部質數 outer: for (int i = 2 ; i <= upper ; i++) { // 用i處於從2開始、到i的平方根的全部數 for (int j = 2 ; j <= Math.sqrt(i) ; j++) { // 若是能夠整除，代表這個數不是質數 if(i != 2 && i % j == 0) { continue outer; } } nums.add(i); } // 使用Toast顯示統計出來的全部質數 Toast.makeText(CalPrime.this , nums.toString() , Toast.LENGTH_LONG).show(); } } }; Looper.loop(); } } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); etNum = (EditText)findViewById(R.id.etNum); calThread = new CalThread(); // 啓動新線程 calThread.start(); } // 爲按鈕的點擊事件提供事件處理函數 public void cal(View source) { // 建立消息 Message msg = new Message(); msg.what = 0x123; Bundle bundle = new Bundle(); bundle.putInt(UPPER_NUM , Integer.parseInt(etNum.getText().toString())); msg.setData(bundle); // 向新線程中的Handler發送消息 calThread.mHandler.sendMessage(msg); } }

Fragment基本概述

Fragment是Android3.0後引入的一個新的API，他出現的初衷是爲了適應大屏幕的平板電腦，固然如今他仍然是平板APP UI設計的寵兒，並且咱們普通手機開發也會加入這個Fragment，咱們能夠把他當作一個小型的Activity，又稱Activity片斷！想一想，若是一個很大的界面，咱們就一個佈局，寫起界面來會有多麻煩，並且若是組件多的話是管理起來也很麻煩！而使用Fragment 咱們能夠把屏幕劃分紅幾塊，而後進行分組，進行一個模塊化的管理！從而能夠更加方便的在運行過程當中動態地更新Activity的用戶界面！另外Fragment並不能單獨使用，他須要嵌套在Activity 中使用，儘管他擁有本身的生命週期，可是仍是會受到宿主Activity的生命週期的影響，好比Activity 被destory銷燬了，他也會跟着銷燬！

ant安裝、環境變量配置及驗證

1、安裝ant

到官方主頁http://ant.apache.org下載新版（目前爲Ant1.8.1）的ant，獲得的是一個apache-ant-1.8.1-bin.zip的壓縮包。將其解壓到你的硬盤上，例如：C:\apache-ant-1.8.1。

2、配置環境變量

window中設置ant環境變量：

ANT_HOME C:/ apache-ant-1.8.1

path C:/ apache-ant-1.8.1/bin

classpath C:/apache-ant-1.8.1/lib

注意：【

　　配置環境變量：個人電腦----屬性-----高級----環境變量
如：ANT_HOME：C:\apache-ant-1.8.1
PATH：%ANT_HOME%\bin （爲了方便在dos環境下操做）

實驗了老是失敗，沒辦法換成地址 C:/ apache-ant-1.8.1/bin，而再也不使用變量。。。成功了。。

】

3、驗證ant

爲了驗證ant是否成功安裝，能夠進行以下操做：

依次選擇：開始->運行->cmd，輸入以下命令：ant

若是出現以下內容，說明安裝成功：

Buildfile: build.xml does not exist!

Build failed

【說明ant安裝成功！由於ant默認運行build.xml文件，這個文件須要咱們創建。】

查看版本：ant -version

但若是出現以下內容，說明安裝失敗：（能夠重複前述步驟，直至安裝成功。）

'ant' 不是內部或外部命令，也不是可運行的程序或批處理文件。

從別處移動過來的：

使用：
(1)在D盤根目錄下創建build.xml

1<?xml version="1.0" encoding="GBK"?>
2<project name="測試腳本" default="copyfile" basedir="." >
3   <target name="copyfile">
4      <copy file="d:/a.txt" todir="e:/Temp" overwrite="true" />
5   </target>
6</project>

（2）在D盤根目錄下創建文件a.txt。
（3）進入dos，
         d:
         ant

         此時可在E:/Temp目錄下見到文件aa.txt，內容與a.txt同樣，即拷貝成功！

Cd\進入根目錄

Cd d:aa鎖定d盤下的aa文件夾

D:則直接進入d盤下的aa文件夾

ant install.demo

ant start.demo

sql語句如何查詢不重複記錄

若是隻使用select distinct [name] from [table]的話後面就不能加order by [score]了

select name,score from tablename group by name,score order by score;

select distinct COMMUNITY_NAME from res_community where COMMUNITY_NAME!=''

出現空的話，xml解析數據會出錯

SQL2000裏的數據類型爲datetime默認值getdate()

mysql建表語句裏把字段default now()?? 這個是不行的，now是在你insert或者update時候寫入的，好比： insert into 表 (字段) values (now());

kcontext.setVariable("setInCode",inCode);將inCode賦值給流程變量setInCode,後面的節點使用input data mapping引用setInCode

//hql

StringBuffer hql = new StringBuffer();

hql.append("select new com.eshine.ump.repo.bo.RepoIn(b.repoName,a.matName")

.append(",a.matModel,a.matUnit,a.inNum,b.inTime,b.inMan,b.inType)")

.append("from RepoInMaterail a,RepoInLog b ")

.append("where a.id.inCode = b.inCode");

//查詢條件

StringBuffer params = new StringBuffer();

String matName = form.get("matName");

if(matName !=null && !"".equals(matName)){

params.append(" and a.matName = '" + matName + "'");

}

String repoName = form.get("repoName");

if(repoName !=null && !"".equals(repoName)){

}

//查詢

Pager p = new Pager();

return this.pageByHqls(hql.toString(), p, null);

}else{

//根據條件查詢

hql.append(params);

        clock += hh + ":";
        if (mm < 10) clock += '0';

關於安卓開發時，調用掃描二維碼的功能時，代碼的理解

分享| 2015-02-04 08:54灬奈丶何氵 | 瀏覽 783 次

App Android 移動開發

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setAction("com.google.zxing.client.android.SCAN");
intent.setClassName("com.google.zxing.client.android", "com.google.zxing.client.android.CaptureActivity");
startActivityForResult(intent, 0);
}
這段代碼的括號內的代碼的意思是什麼？如今我主要看不懂的是最後一行的startActivityForResult(intent, 0);這行的做用和意思是什麼？

2015-02-04 09:33提問者採納

最後一行和startActivity區別是
在這個activity裏面會重寫這個方法onActivityResult（int requestCode, int resultCode, Intent data）；當跳轉到CaptureActivity後執行能夠返回給上面你提供代碼的activity數據經過setResult( int resultCode, data); 來傳遞。有點相似回調、
裏面的0就是重寫方法裏面的第一個參數用來判斷的做用。

1.解析簡單的josn格式字符串

String msg = "{'rs':0,'fs':'登陸成功!'}";

JSONObject jsonObject = new JSONObject(msg);

System.out.println(jsonObject.getString("fs"))

1. List receiveList = offDao.findByHql(hql, page, row);

2. if(receiveList.size()>0&&receiveList!=null){

3. Iterator it = receiveList.iterator();

4. while(it.hasNext()){

5. Object[] object = (Object[])it.next();

6. OffAnnouncementReceive offReceive = new OffAnnouncementReceive();

7. String consigneeid=object[0].toString();

8. String flgs = object[1].toString();

9. String sendmail = object[2].toString();

10. String sendPeo = object[4].toString();

11. Date sendDate = (Date)object[5];

12. String announcementReceiveId = object[6].toString();

13. offReceive.setAnnouncementReceiveId(announcementReceiveId);

14. offReceive.setConsigneeId(consigneeid);

15. offReceive.setSendmailId(sendmail);

16. if(sendDate!=null&&!sendDate.equals("")){

17. offReceive.setSendDate(sdf.format(sendDate));

18. }

19. }

20. }

使用sql返回的list<Object>轉成須要的實體對象，看下面的Map的使用,很方便（須要將Query對象setResultTransformer）：

[java] view plain copy

1. List list = session.createSQLQuery(sql)

2. .setResultTransformer(

3. Transformers.ALIAS_TO_ENTITY_MAP)

4. .list();

5. //此時，每一個Object能夠轉換成一個Map

6. Map map = (Map) list.get(i);

7. map.get("student_id"); //這裏的key 必定是數據庫對應的字段名才行

作項目的時候遇到這樣的問題，hibernate執行SQL語句返回來的list集合調試斷點的時候檢查list集合有值，可是返回action遍歷的時候在list.get(i);這句話時報異常，調試結果是list集合爲空，查找到的結果就是用SQL語句不能自動轉換成bean對象，因此要轉換成數組形式在進行遍歷，這時返回的list集合裏的值就能夠遍歷出來了.

偷個懶把別人的代碼粘過來了，還有個錯誤沒有寫，有時間在總結吧：

Hibernate執行sql語句

Hibernate執行sql語句：
BasicServiceImpl basicServiceImpl = new BasicServiceImpl();
String hql = "select * from AccountInfo where selfId='0000100003' or(left(selfId,10)='0000100004' and
nodeSum=0)";

*寫SQL語句的時候作好給表名起個別名

TManager tManager = TManagerImpl.getInstance();
List accountList = tManager.getSession().createSQLQuery(hql).list();
//List accountList = tManager.getSession().createSQLQuery(hql).addEntity(AccountInfo.class).list();
for(int i=0;i<accountList.size();i++){
Object[] objects = (Object[])accountList.get(i);
for(int j=0;j<objects.length;j++){
System.out.println(objects[j].getClass().getName());// 從這個輸出結果能夠看出，objects[j]的
值其實是AccountInfo的屬性（表的字段）而不是AccountInfo對象，
}
System.out.println(objects.length);
}
信息: java.lang.ClassCastException:Ljava.lang.Object; cannot be cast to net.yjiasoft.sss.table.AccountInfo
分析：原來是查詢出來的字段並不能自動轉換爲bean對象，因此要添加addEntity(Clazz class)。
擴展：
1.SQL返回一個Map對象，也就是說在在list裏包含多個Map，代碼以下
Query query = session.createSQLQuery("select id,name from Tree t where pid in (select id from Tree) ").setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP); //返回一個map,KEY:爲DB中名稱一致（大小寫一致）遍歷list時就能夠
Map map = (Map)list.get[i];
map.get("id");map.get("name");來取值。按你的SQL語句select後的字段名來做爲map的Key，但這個key必須與數據庫中的字段名如出一轍。
2.能夠用做函數方面的。如
Query query = session.createSQLQuery("select sum(id) SUMID from Tree t where pid in (select id from Tree)
.addScalar("SUMID",Hibernate.INTEGER) //轉換類型，按DB中的type轉
.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP); //返回一個map,KEY:爲DB中名稱一致（大小寫一致）
直接就map.get("SUMID")能夠取值了
還有一點就是這個方法在Hibernate3.2版本上才能正常運行。
3.hibernate 中createQuery與createSQLQuery二者區別是：
前者用的hql語句進行查詢，後者能夠用sql語句查詢
前者以hibernate生成的Bean爲對象裝入list返回
後者則是以對象數組進行存儲
因此使用createSQLQuery有時候也想以hibernate生成的Bean爲對象裝入list返回，就不是很方便
忽然發現createSQLQuery有這樣一個方法能夠直接轉換對象
Query query = session.createSQLQuery(sql).addEntity(XXXXXXX.class);
XXXXXXX 表明以hibernate生成的Bean的對象，也就是數據表映射出的Bean。
呵呵之後多注意，仍是時不時的要看看hibernate各個對象方法的使用。
還有另一個相關的小細節應注意：
好比有這樣一個po
PO: User.class
properties: userId,userName
DDL: create table tuser (userid varchar(10),username varchar(20));
當執行：
session.createQuery("from User u").list()時生成的SQL：
select userid,username from tuser;
當執行：
session.createQuery("from User u").iterator()時生成的SQL：
select userid from tuser;
能夠看出list()一次將數據從數據庫中讀出直接填充到List中
iterator()將數據的主鍵從數據庫中讀出，當循環這個Iterator時才添加執行：
select userid,username from user where userid=?;把數據讀出。
在不一樣的應用範圍使用不一樣的方法，具體在hibernate應用中應當注意。

select * from " + tableName + " where 1=0

用於查看錶結構，而不讀取數據記錄

public boolean isTableCreate(String tableName) {

try {

String sql = "select * from " + tableName + " where 1=0";

jdbcDao.queryForList(sql);

return true;

} catch (Exception e) {

return false;

}

JAVA發送手機短信,流傳有幾種方法:(1)使用webservice接口發送手機短信,這個可使用sina提供的webservice進行發送,可是須要進行註冊;(2)使用短信mao的方式進行短信的發送,這種方式應該是比較的經常使用,前提是須要購買硬件設備,呵呵(3)使用中國網建提供的SMS短信平臺（申請帳號地址：http://sms.webchinese.cn/default.shtml）

本程序主要是運用了中國網建提供的SMS短信平臺，這個短信平臺基於java提供個專門的接口

Js定時器

1.倒計定時器：timename=setTimeout("function();",delaytime);

2..循環定時器：timename=setInterval("function();",delaytime);

3.用clearTimeout(timename) 來關閉倒計時定時器，而用clearInterval(timename)來關閉循環定時器。

網站大併發解決方案

使用高性能的服務器、高性能的數據庫、高效率的編程語言、還有高性能的Web容器。

小成本方法：

一、HTML靜態化

1. 將部份內容進行後臺更新的時候進行靜態化，這樣避免了大量的數據庫訪問請求。當咱們每次更新了數據庫中的相應信息之後，咱們即可以從新執行這個方法，將這個頁面從新靜態化，當咱們每次訪問這個網頁的時候便不會每一次都去數據庫中查詢數據了，而是訪問的一個已經一次性生成了的靜態頁面，這也就達到了提升網站運行速度的目標。 //防止瀏覽器緩存，用於從新生成新的html

2. UUID uuid = UUID.randomUUID();

3. Writer out = new OutputStreamWriter(new FileOutputStream(dirPath+"/"+uuid+indexFileName),"UTF-8");

4. ProcessClient.processBody(out);

5. response.sendRedirect("templates/html/"+uuid+"index.html");

二、圖片服務器分離

三、數據庫集羣和庫表散列

負載均衡 1：如何實現多應用服務器間的session共享：（一臺服務器崩潰，另一臺服務器能夠繼續支持）

2：如何分發請求到各個應用服務器實現壓力分解：（這裏的解決方案是用apache作 web服務器）

T - Type（Java 類）

K - Key（鍵）

V - Value（值）

N - Number（數值類型）

？ - 表示不肯定的java類型

S、U、V -2nd、3rd、4th types

爲java配置本地環境變量，並測試java環境是否配置成功。

#vi /etc/profile

JAVA_HOME=/usr/local/java

JRE_HOME=/usr/local/java/jre

CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib

PATH=$JAVA_HOME/bin:$PATH

Linux下Tomcat的安裝配置

一.下載安裝對應的jdk,並配置Java環境。

官網下載地址：

http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html

下載將jdk加壓後放到/usr/local目錄下：

[root@master ~]#chmod 755 jdk-6u5-linux-x64.bin

[root@master ~]# ./jdk-6u5-linux-x64.bin

[root@master ~]#mv jdk1.6.0_05 /usr/local

創建/usr/local/下的jdk軟鏈接方便之後版本升級：

[root@master ~]# ln -s /usr/local/jdk1.6.0_05/ /usr/local/jdk

配置環境變量：

在 /etc/profile 中加入如下內容：

JAVA_HOME=/usr/local/jdk1.6.0_05

JAVA_BIN=/usr/local/jdk1.6.0_05/bin

PATH=$PATH:$JAVA_BIN

CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export JAVA_HOME JAVA_BIN PATH CLASSPATH

保存退出

[root@master ~]source /etc/profile

查看java環境變量是否生效

[root@master ~]# java -version

java version "1.6.0_05"

Java(TM) SE Runtime Environment (build 1.6.0_05-b13)

Java HotSpot(TM) 64-Bit Server VM (build 10.0-b19, mixed mode)

測試成功

二．下載安裝tomcat（http://tomcat.apache.org/）

[root@master ~]# unzip apache-tomcat-6.0.30.zip

[root@master ~]# mv apache-tomcat-6.0.30/ /usr/local/

[root@master ~]cd /usr/local/

[root@master local]# ln -s /usr/local/apache-tomcat-6.0.30/ /usr/local/tomcat

[root@master local]# cd tomcat/bin/

[root@master bin]#ls

[root@master bin]#vim catalina.sh

添加如下內容：

CATALINA_HOME=/usr/local/apache-tomcat-6.0.30/

[root@master local]#chmod +x *.sh

三．啓動tomcat服務器

[root@master tomcat]# /usr/local/tomcat /bin/catalina.sh start

Using CATALINA_BASE: /usr/local/apache-tomcat-6.0.30/

Using CATALINA_HOME: /usr/local/apache-tomcat-6.0.30/

Using CATALINA_TMPDIR: /usr/local/apache-tomcat-6.0.30//temp

Using JRE_HOME: /usr/local/jdk1.6.0_05

Using CLASSPATH: /usr/local/apache-tomcat-6.0.30//bin/bootstrap.jar

[root@master logs]# cd /usr/local/tomcat/logs/

[root@master logs]# tail -f catalina.out

at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)

at java.lang.reflect.Method.invoke(Method.java:597)

at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289)

at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414)

Jul 4, 2011 11:06:57 AM org.apache.coyote.http11.Http11Protocol pause

INFO: Pausing Coyote HTTP/1.1 on http-8080

Jul 4, 2011 11:06:58 AM org.apache.catalina.core.StandardService stop

INFO: Stopping service Catalina

Jul 4, 2011 11:06:58 AM org.apache.coyote.http11.Http11Protocol destroy

INFO: Stopping Coyote HTTP/1.1 on http-8080

四．在瀏覽器中輸入

http://localhost:8080/（若是不是本機，則輸入對應的ip地址）

測試出現tomcat頁面則測試成功

ps：須要說明的是tomcat的默認測試頁面是放在webapps下面，這個實際上是在server.xml文件中配置的，以下所示：

[root@SOR_SYS apache-tomcat-6.0.30]# ls
LICENSE NOTICE RELEASE-NOTES RUNNING.txt bin conf lib logs temp webapps work

1)webapps文件夾主要用於web應用程序部署，好比你能夠把你的應用程序包，如war文件拷到該目錄下，容器會自動部署。
　　2)conf文件夾下主要是放置tomcat的服務器的相關配置文件

五。添加應用，再次進行測試

在webapps目錄下放測試包（注意：webaapps目錄下面主要是放應用包的.war在tomcat重啓訪問後會自動解壓）

[root@master webapps]# pwd
/usr/local/tomcat/webapps

[root@master webapps]# tar -zxvf moni2.tar.gz

[root@master webapps]# ls
docs examples host-manager manager moni2 moni2.tar.gz ROOT

[root@master webapps]# /usr/local/tomcat/bin/catalina.sh start（重啓tomcat）
Using CATALINA_BASE:   /usr/local/apache-tomcat-6.0.30/
Using CATALINA_HOME:   /usr/local/apache-tomcat-6.0.30/
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-6.0.30//temp
Using JRE_HOME:        /usr/local/jdk1.6.0_05
Using CLASSPATH:       /usr/local/apache-tomcat-6.0.30//bin/bootstrap.jar

在瀏覽器中輸入以下地址：

http://192.168.55.229:8080/moni2/

六。修改tomcat的監聽端口

[root@master ~]# cd /usr/local/tomcat/conf

[root@master ~]# ls

[root@master ~]# vim server.xml

<Server port="8005" shutdown="SHUTDOWN">【中止tomcat時的端口】

<Connector port="8081" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" /> 【tomcat默認的監聽端口是8080，如今改爲8081】

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />【apache+tomcat模式時訪問tomcat的端口】

如今重啓tomcat。訪問http://192.168.55.229:8081/moni2/【注意：這時就須要修改端口了，嘿嘿。。。】

(1)load(InputStream inStream)

　　這個方法能夠從.properties屬性文件對應的文件輸入流中，加載屬性列表到Properties類對象。以下面的代碼：

Properties pro = new Properties();FileInputStream in = new FileInputStream("a.properties");pro.load(in);in.close();

(2)store(OutputStream out, String comments)

這個方法將Properties類對象的屬性列表保存到輸出流中。以下面的代碼：

FileOutputStream oFile = new FileOutputStream(file, "a.properties");pro.store(oFile, "Comment");oFile.close();

public static Properties loadProperty(String propFileName) {

InputStream inputStream = PropertiesUtil.class.getResourceAsStream("/"

+ propFileName);

Properties properties = new Properties();

try {

properties.load(inputStream);

} catch (IOException e) {

e.printStackTrace();

} finally {

if (inputStream != null)

try {

inputStream.close();

} catch (IOException e) {

e.printStackTrace();

}

return properties;

}

Java GC:修改eclipse.ini文件參數。

Eclipse dropins文件夾放插件。

使用自定義標籤函數<%@ taglib prefix="fns" uri="/WEB-INF/tlds/fns.tld" %>

<description>獲取當前用戶的菜單對象列表</description>

<name>getMenuList</name>

<function-class>com.yida.modules.sys.utils.UserUtils</function-class>

<function-signature>java.util.List getMenuList()</function-signature>

<example>${fns:getMenuList()}</example>

</function>

使用SHIRO的步驟： 1，導入jar 2，配置web.xml 3，創建dbRelm 4，在Spring中配置

@Service @Transactional public class MyShiro extends AuthorizingRealm{ @Inject private UserService userService; /** * 權限認證 */ @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { //獲取登陸時輸入的用戶名 String loginName=(String) principalCollection.fromRealm(getName()).iterator().next(); //到數據庫查是否有此對象 User user=userService.findByName(loginName); if(user!=null){ //權限信息對象info,用來存放查出的用戶的全部的角色（role）及權限（permission） SimpleAuthorizationInfo info=new SimpleAuthorizationInfo(); //用戶的角色集合 info.setRoles(user.getRolesName()); //用戶的角色對應的全部權限，若是隻使用角色定義訪問權限，下面的四行能夠不要 List<Role> roleList=user.getRoleList(); for (Role role : roleList) { info.addStringPermissions(role.getPermissionsName()); } return info; } return null; } /** * 登陸認證; */ @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken authenticationToken) throws AuthenticationException { //UsernamePasswordToken對象用來存放提交的登陸信息 UsernamePasswordToken token=(UsernamePasswordToken) authenticationToken; //查出是否有此用戶 User user=userService.findByName(token.getUsername()); if(user!=null){ //若存在，將此用戶存放到登陸認證info中 return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), getName()); } return null;

一、使用註解@AspectJ定義切面

applicationcontext.xml里加入

AOP的XML命名空間和聲明相關schema
命名空間:
xmlns:aop="http://www.springframework.org/schema/aop"
schema聲明:
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.0.xsd

加入<aop:aspectj-autoproxy />標籤
@Aspect
@Service

public class HttpAspect {
private static final org.apache.log4j.Logger logger = org.apache.log4j.Logger
.getLogger(HttpAspect.class);

//用於累加週期
private static long start = 0L;
private static long end = 0L; //控制時鐘週期
private static final long invet = 1000L*60*60L;
private static int callTimes = 0;

java中的==是用來判斷對象所使用的內存地址是否是同一個，進而判斷是否是同一個對象。例如 objA == objB 注意這裏是同一個對象纔會是true，若是不是同一個對象，哪怕兩個對象全部屬性都相同也會返回false。而equals則是一個方法，你能夠爲本身的類編寫equals方法來判斷是否是相等。這裏String類就提供了equals方法來判斷兩個String對象是否是相同，而不是去判斷兩個String對象是否是同一個對象，由於咱們通常使用中，只關心兩個字符串內容相同與否，而不會關心是否是同一個對象。出口流水查詢:services/http/getPayInfoLaneexlist?timestamp=1472789678890&signature=2E4353402DC178521B92256D4668FE3EB8592BA9&items={"starttime":"2016-03-28 00:00:00","endtime":"2016-04-01 00:00:00"} 出口流水擴展查詢:services/http/getPayInfoLaneexlistext?timestamp=1472789678890&signature=2E4353402DC178521B92256D4668FE3EB8592BA9&items={"starttime":"2016-03-28 00:00:00","endtime":"2016-04-01 00:00:00"} 獲取路段列表url:services/http/getRoad?timestamp=1472789678890&signature=F975EE6528E455ED5055F345D81D75069AAE81B7 獲取站列表url:services/http/getStation?timestamp=1472789678890&signature=F975EE6528E455ED5055F345D81D75069AAE81B7 HttpClient client = new HttpClient();///建立HttpClient實例 HttpMethod method = new GetMethod(url);//建立請求鏈接方法的實例 method.setRequestHeader( "Content-Type", "text/html;charset=utf-8" ); client.executeMethod( method );//用HttpClient實例的execute方法來執行第二步中建立好的 method 實例 System.out.println( method.getStatusLine() );// 打印服務器返回的狀態取得目標地址的內容有三種方法：第一種，getResponseBody，該方法返回的是目標的二進制的byte流；第二種，getResponseBodyAsString，這個方法返回的是String類型，值得注意的是該方法返回的String的編碼是根據系統默認的編碼方式，因此返回的String值可能編碼類型有誤，在本文的"字符編碼"部分中將對此作詳細介紹；第三種，getResponseBodyAsStream，這個方法對於目標地址中有大量數據須要傳輸是最佳的。在這裏咱們使用了最簡單的 InputStream inputStream=method.getResponseBodyAsStream(); ByteArrayOutputStream output = new ByteArrayOutputStream(); byte[] buffer = new byte[4096]; int n = 0; while (-1 != (n = inputStream.read(buffer))) { output.write(buffer, 0, n); } byte[] body = output.toByteArray();

//異常信息 String errInfo=jobj.optString("errInfo"); //數據壓縮字符串 String data=jobj.optString("data"); //解壓數據 String dataGunzip=ZipUtils.gunzip(data); //System.out.println(dataGunzip); JSONObject jsonobj =JSONObject.fromObject(dataGunzip);

java接收參數代碼： String title = request.getParameter("title"); title = URLDecoder.decode(title, "UTF-8");
