maven集成SSM項目，Tomcat部署運行——SSM整合框架搭建
第一步：添加相關依賴包前端
各類包，分爲爲：springDI依賴包（最基礎的必備包），AOP相關依賴，springMVC依賴包，servlet及jsp相關依賴，數據庫庫依賴包，mybatis及Mybatis-spring依賴包等，上代碼pom.xmljava

</project>
第二步，配置幾個基礎文件。應該從web.xml入手。這個是整個web程序的入口，至關於java的main函數，我在實際編碼時並無按照這個順序，這裏爲了邏輯清楚，可以串聯起來，我仍是從這裏提及，上代碼；並將進行相應說明：mysql
一、配置web.xmlweb
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> 3 <display-name>OrdersForGoods</display-name> 4 5 <display-name>Archetype Created Web Application</display-name> 6 <!-- 配置監聽器加載上下文參數spring的配置文件 ,這個的做用是當tomcat啓動程序時，首先會監聽，加載相應的配置， 比如是application讀取文件流，構建一個bean工廠，用來爲依賴注入DI作準備--> 7 <context-param> 8 <param-name>contextConfigLocation</param-name> 9 <param-value>classpath:applicationContext-mybatis.xml</param-value> 10 </context-param> 11 <listener> 12 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 13 </listener> 14 <!-- 配置springmvc的servlet ，前端控制器做用就不說了，你們都明白--> 15 <servlet> 16 <servlet-name>springmvc</servlet-name> 注意：這裏的的名字必定要和springMVC的配置文件XXX-servlet.xml中的XXX名字徹底相等，不然報錯 17 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 18 <init-param> 19 <param-name>contextConfigLocation</param-name> 20 <param-value>classpath:springmvc-servlet.xml</param-value> 21 </init-param> 22 <load-on-startup>1</load-on-startup> 23 </servlet> 24 <servlet-mapping> 25 <servlet-name>springmvc</servlet-name> 26 <url-pattern>/</url-pattern><!--這裏用/是根目錄的意思，以前我用/*是有問題的，這二者仍是有區別的，你們自行文度娘--> 27 </servlet-mapping> 28 <!-- 配置過濾器 設置編碼格式--> 29 <filter> 30 <filter-name>encoding</filter-name> 31 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 32 <init-param> 33 <param-name>encoding</param-name> 34 <param-value>utf-8</param-value> 35 </init-param> 36 </filter> 37 <filter-mapping> 38 <filter-name>encoding</filter-name> 39 <url-pattern>/*</url-pattern> 40 </filter-mapping> 41 <!-- 配置log4j日誌的監聽 容器啓動就加載，同加載applicationContext.xml相似--> 42 <context-param> 43 <param-name>log4j</param-name> 44 <param-value>classpath:log4j.properties</param-value> 45 </context-param> 46 <listener> 47 <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> 48 </listener> 49 </web-app>
二、applicationContext.xmlredis
1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
3 xmlns="http://www.springframework.org/schema/beans"
4 xmlns:aop="http://www.springframework.org/schema/aop"
5 xmlns:context="http://www.springframework.org/schema/context"
6 xmlns:tx="http://www.springframework.org/schema/tx"
7 xmlns:cache="http://www.springframework.org/schema/cache"
8 xmlns:p="http://www.springframework.org/schema/p"
9 xsi:schemaLocation="http://www.springframework.org/schema/beans
10 http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
11 http://www.springframework.org/schema/aop
12 http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
13 http://www.springframework.org/schema/context
14 http://www.springframework.org/schema/context/spring-context-4.3.xsd
15 http://www.springframework.org/schema/tx
16 http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
17 http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.3.xsd"
18 >
19 <!-- 加載jdbc屬性文件 -->
20 <context:property-placeholder location="classpath:jdbc.properties"/>
21 <!-- 配置數據源 -->
22 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" scope="singleton">
23 <property name="driverClassName" value="${jdbc.driver}"/>
24 <property name="url" value="${jdbc.url}"/>
25 <property name="username" value="${jdbc.username}"/>
26 <property name="password" value="${jdbc.password}"/>
27 </bean>
28 <!-- 讓事務註解生效 -->
29 <tx:annotation-driven/>
30 <!--配置事務 -->
31 <bean id="transaction" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
32 <property name="dataSource" ref="dataSource"/>
33 </bean>
34 <!-- 配置mybatis的sqlSessionFactory -->
35 <bean id="sqlSession" class="org.mybatis.spring.SqlSessionFactoryBean">
36 <property name="dataSource" ref="dataSource"/>
37 <property name="configLocation" value="classpath:mybatis-config.xml"/>
38 </bean>
39 <!-- mapper 接口所在包名，spring自動查找下面mapper.xml並生產相應實例，讓接口和xml相關聯 -->
40 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
41 <property name="basePackage" value="com.yusys.dao"/>
42 </bean>
43
44 </beans>
三、springmvc-servlet.xmlspring
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xmlns:mvc="http://www.springframework.org/schema/mvc" 7 xsi:schemaLocation=" 8 http://www.springframework.org/schema/beans 9 http://www.springframework.org/schema/beans/spring-beans.xsd 10 http://www.springframework.org/schema/context 11 http://www.springframework.org/schema/context/spring-context.xsd 12 http://www.springframework.org/schema/mvc 13 http://www.springframework.org/schema/mvc/spring-mvc.xsd"> 14 <!-- 使項目全部註解生效 --> 15 <context:component-scan base-package="com.yusys"/> 16 <!-- 配置視圖解析器 --> 17 <bean id="" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 18 <property name="prefix" value="/WEB-INF/jsp/"/> 19 <property name="suffix" value=".jsp"/> 20 </bean> 21 22 23 24 </beans>
四、mybatis-config.xmlsql
這個文件配置不多，主要是由於在SSM整合中，實際上主要是整合了mybatis，以前由mybatis進行配置的與數據庫的聯繫全交給了spring去作，如數據源、鏈接池、事務等等。這些交給spring之後，當程序須要的時候，就會依賴注入的方式提供給程序用。springmvc主要做用能夠先簡單理解爲調配調用，視圖解析。數據庫
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 5 <configuration> 6 <settings> 7 <setting name="lazyLoadingEnabled" value="true"/> 8 </settings> 9 <typeAliases> 10 <package name="com.yusys.entity"/> 11 </typeAliases> 12 </configuration>
基礎的配置文件就是這些，至於mapper.xml，屬於dao層的內容，我傾向於將它理解爲java代碼的另外一種特殊存在形式，放在後文進行說明express
第三步、就是編寫代碼了（這裏只是爲了演示說明這個過程，就放一個相關的entity、dao、service、controller，其餘的有興趣的本身添加補充）。apache
一、entity實體類
1 package com.yusys.entity;
2
3 import java.util.Date;
4
5 public class NewsDetail {
6
7 private int id;
8 private String title;
9 private String summary;
10 private String author;
11 private Date createdate;
12 public int getId() {
13 return id;
14 }
15 public void setId(int id) {
16 this.id = id;
17 }
18 public String getTitle() {
19 return title;
20 }
21 public void setTitle(String title) {
22 this.title = title;
23 }
24 public String getSummary() {
25 return summary;
26 }
27 public void setSummary(String summary) {
28 this.summary = summary;
29 }
30 public String getAuthor() {
31 return author;
32 }
33 public void setAuthor(String author) {
34 this.author = author;
35 }
36 public Date getCreatedate() {
37 return createdate;
38 }
39 public void setCreatedate(Date createdate) {
40 this.createdate = createdate;
41 }
42
43 }
二、dao層
1 package com.yusys.dao;
2
3 import java.util.List;
4
5 import com.yusys.entity.NewsDetail;
6
7 public interface NewsDetailMapper {
8
9 public List<NewsDetail> getAll();
10
11 public List<NewsDetail> getNewsDetailByTitle();
12 }
1 <?xml version="1.0" encoding="UTF-8" ?>
2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
3 "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
4 <mapper namespace="com.yusys.dao.NewsDetailMapper">
5 <select id="getAll" resultType="NewsDetail">
6 select * from news_detail
7 </select>
8 <select id="getNewsDetailByTitle" parameterType="NewsDetail" resultType="NewsDetail">
9 select * from news_detail where title like concat('%',#{title},'%')
10 </select>
11 </mapper>
三、service層
1 package com.yusys.service;
2
3 import java.util.List;
4
5 import com.yusys.entity.NewsDetail;
6
7 public interface NewsDetailService {
8
9 public abstract List<NewsDetail> getAll();
10
11 public abstract List<NewsDetail> getNewsDetailByTitle();
12
13 }
1 package com.yusys.service;
2
3 import java.util.List;
4
5 import org.springframework.beans.factory.annotation.Autowired;
6 import org.springframework.stereotype.Service;
7
8 import com.yusys.dao.NewsDetailMapper;
9 import com.yusys.entity.NewsDetail;
10 @Service
11 public class NewsDetailServiceImpl implements NewsDetailService {
12 @Autowired
13 NewsDetailMapper newsDetailMpper;
14
15 /* (non-Javadoc)
16 * @see com.yusys.service.NewsDetailService#getAll()
17 */
18 @Override
19 public List<NewsDetail> getAll(){
20 return newsDetailMpper.getAll();
21 }
22
23 /* (non-Javadoc)
24 * @see com.yusys.service.NewsDetailService#getNewsDetailByTitle()
25 */
26 @Override
27 public List<NewsDetail> getNewsDetailByTitle(){
28 return newsDetailMpper.getNewsDetailByTitle();
29 }
30 }
四、controller層
1 package com.yusys.controller;
2
3 import java.util.List;
4
5 import org.springframework.beans.factory.annotation.Autowired;
6 import org.springframework.stereotype.Controller;
7 import org.springframework.ui.Model;
8 import org.springframework.web.bind.annotation.RequestMapping;
9
10 import com.yusys.entity.NewsDetail;
11 import com.yusys.service.NewsDetailService;
12 @Controller
13 public class NewsDetailController {
14 @Autowired
15 NewsDetailService newsDetailService;
16
17 @RequestMapping(value="/newsDetailList")
18 public String getAllDetail(Model model){
19 List<NewsDetail> list=newsDetailService.getAll();
20 model.addAttribute("list", list);
21 return "newsDetail";
22 }
23 }
第四步、建立newsDetail.jsp進行顯示。
第五步、部署tomcat進行運行
一、
二、
三、點擊下一步後添加項目後finish
四、tomcat未啓動是雙擊
五、進入Overview界面，選擇如下配置，關閉該界面
六、啓動tomcat，運行程序，注掉controller中的方法調用，讓其直接轉到jsp頁面，效果顯現，一切OK，可是放開裏面的方法，出現了問題，mysql的jar和tomcat的jar衝突的問題，具體問題及其餘見相應的博文——maven集成SSM項目，Tomcat部署運行——SSM整合框架搭建
