1、開發環境:html
(1) OS:Windows 7java
(2) DB:MySql 5.1.6mysql
(3) JDK:1.8.0_17web
(4) Server:Apache Tomcat 8.0.26spring
(5) IDE:Eclipsesql
2、SSH框架版本:apache
(1) Struts2.3.2session
(2) Spring4.0.2app
(3) Hibernate5.2.5框架
注意:我根據須要並無導入全部JAR 包;
3、配置Sturts2框架:
1.在eclipse新建一個項目news;
2.導入Sturts2.X的jar包;
3.而後配置在WebContext/WEB-INF/web.xml:
1 <display-name>news</display-name> 2 <welcome-file-list> 3 <welcome-file>default.jsp</welcome-file> 4 </welcome-file-list> 5 <filter> 6 <filter-name>struts2</filter-name> 7 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 8 </filter> 9 <filter-mapping> 10 <filter-name>struts2</filter-name> 11 <url-pattern>/*</url-pattern> 12 </filter-mapping>
注意:default.jsp表明一個默認首頁;
注意:/*表明過濾全部;
注意:struts2的入口是一個過濾器,因此能夠把struts2當過濾器來配置;
4.而後配置src/struts.xml
<!-- 第1步:先定義一個包 --> <package name="mypck001" extends="struts-default"> <!-- myNewsAction用於spring注入 --> <action name="NewsAction_*" class="myNewsAction" method="{1}"> <result name="success">/WEB-INF/jsp/index.jsp</result> <result name="deleteOK">/WEB-INF/jsp/ok.jsp</result> <result name="deleteFailed">/WEB-INF/jsp/error_delete.jsp</result> </action> </package>
注意:NewsAction_*表明全部以NewsAction_開頭的地址;
注意:{1}表明方法名跟NewsAction_*中*的值同樣;
5.而後建立4個jsp文件:default.jsp、Index.jsp、ok.jsp、error.jsp
default.jsp文件放在WEBContext目錄下,很方便的跳轉運行項目;
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<% response.sendRedirect("myNews2Action_getMyNewsAll.action"); %>
</body>
</html>
其餘三個,爲了防止用戶直接訪問JSP頁面把它們放在WEB-INF下;
6.而後再src目錄myNews2.action包下建立MyNews2Action.action;
4、配置spring框架:
1.添加spring jar包;
注意:spring框架須要經過struts2-spring-plugin-2.3.30 jar 以struts插件的形式鏈接struts;
2.而後配置web.xml
1 <context-param> 2 <param-name>contextConfigLocation</param-name> 3 <param-value>classpath:applicationContext.xml</param-value> 4 </context-param> 5 <listener> 6 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 7 </listener>
注意:spring以監聽器的形式監聽全部實例的建立;
注意:applicationcontext.xml是spring的配置文件,由於它的默認查找路徑在WEB—INF/classses下,而咱們要把它放到src下就在這配置一下;
3.而後在src目錄下建立jdbc.properties文件,目的是但願防止不應碰applicationContext.xml文件的人碰它;
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/news jdbc.user=root jdbc.password=123456
4.而後配置applicationContext.xml:
<context:component-scan base-package="myNews2" />
注意:它是spring註解解析器,用註解能夠各類<Bean>的建立;
<context:property-placeholder location="classpath:jdbc.properties" />
!引入jdbc.properties;
5.而後對各個類進行IOC的注入:
1 @Repository 2 @Scope("prototype") 3 public class MyNewsDaoImpl implements MyNewsDao { 4 5 @Resource 6 private SessionFactory sf;
注意:@Repository表明這個類的實例交給spring來管理;
@Controller @Scope("prototype") public class MyNews2Action extends ActionSupport{ @Resource private MyNewsService ms;
注意:@Scope("prototype")表明這個類的做用範圍;
@Service @Scope("prototype") public class MyNews2ServiceImpl implements MyNewsService { @Resource private MyNewsDao mn;
注意:模型層用@Service,控制層用@Controller,數據層用@Repository;
注意:@Resource是JDK 解析器;spring的是@Autowired和Qualifier;
5、配置Hibernate框架:
1.添加Hibernate jar包;
2.配置applicationContext.xml文件:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd"> <context:component-scan base-package="myNews2" /> <context:property-placeholder location="classpath:jdbc.properties" /> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean" scope="prototype"> <property name="dataSource" ref="dataSource"></property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <!-- 禁用自動提交,保護事務的完整性 --> <prop key="hibernate.connection.autocommit">false</prop> <!-- 開機自動生成表 --> <prop key="hibernate.hbm2ddl.auto">update</prop> </props> </property> <property name="mappingResources"> <list> <value>News.hbm.xml</value> </list> </property> </bean> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" > <property name="driverClass" value="${jdbc.driver}" /> <property name="jdbcUrl" value="${jdbc.url}" /> <property name="user" value="${jdbc.user}" /> <property name="password" value="${jdbc.password}" /> <!-- 每300秒檢查全部鏈接池中的空閒鏈接 --> <property name="idleConnectionTestPeriod" value="300"></property> <!-- 最大空閒時間,900秒內未使用則鏈接被丟棄。若爲0則永不丟棄 --> <property name="maxIdleTime" value="900"></property> <!-- 最大鏈接數 --> <property name="maxPoolSize" value="2"></property> </bean> </beans>
3.配置News.hbm.xml文件:
<?xml version="1.0" encoding="UTF-8"?> <hibernate-mapping xmlns="http://www.hibernate.org/xsd/hibernate-mapping"> <class name="myNews2.entity.News" table="news"> <id name="id" column="id"> <generator class="native"/> </id> <!-- 屬性對應字段 --> <property name="title" type="string" length="50" column="title" not-null="true"></property> <property name="content" type="text" length="50000" column="content" not-null="true"></property> <property name="begintime" type="date" column="begintime" not-null="true"></property> <property name="username" type="string" length="20" column="username" not-null="true"></property> </class> </hibernate-mapping>
