一、准备工作
开始之前，先参考上一篇：
struts2.3.24 + spring4.1.6 + hibernate4.3.11 + mysql5.5.25 开发环境搭建及相关说明
思路都是一样的，只不过把struts2替换成了spring mvc

二、不同的地方
工程目录及jar包：

action包改成controller；
删除struts2 jar包，添加spring mvc包（已有的话，不需添加）；

web.xml配置：

跟之前不同的地方是把struts2的过滤器替换成了一个servlet，主要目的是路由url，交给spring mvc处理；

<?xml version="1.0" encoding="UTF-8"?><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"> <display-name>SSH</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath:springmvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping></web-app>

applicationContext.xml配置：
不同的地方主要是配置自动扫描的时候，要排除@Controller组件，这些bean是由spring mvc 去生成的；
其它配置跟前一篇一样；

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xsi:schemaLocation="  http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd  http://www.springframework.org/schema/aop  http://www.springframework.org/schema/aop/spring-aop.xsd  http://www.springframework.org/schema/tx  http://www.springframework.org/schema/tx/spring-tx-4.1.xsd  http://www.springframework.org/schema/jdbc  http://www.springframework.org/schema/jdbc/spring-jdbc-4.1.xsd  http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context-4.1.xsd">  <!-- scans the classpath for annotated components (including @Repostory  and @Service that will be auto-registered as Spring beans -->   <context:component-scan base-package="ssh" > <!--排除@Controller组件，该组件由SpringMVC配置文件扫描 --> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <!--配数据源 --> <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="com.mysql.jdbc.Driver" /> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/demo" /> <property name="user" value="root" /> <property name="password" value="root" />  <property name="acquireIncrement" value="1"></property>  <property name="initialPoolSize" value="80"></property>  <property name="maxIdleTime" value="60"></property>  <property name="maxPoolSize" value="80"></property>  <property name="minPoolSize" value="50"></property>  <property name="acquireRetryDelay" value="1000"></property>  <property name="acquireRetryAttempts" value="60"></property>  <property name="breakAfterAcquireFailure" value="false"></property> <!-- 如出现Too many connections, 注意修改mysql的配置文件my.ini,增大最多连接数配置项,(查看当前连接命令:show processlist) --> </bean>  <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="hibernateProperties">  <props>  <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>  <prop key="hibernate.show_sql">true</prop>  <prop key="hibernate.hbm2ddl.auto">update</prop>  <prop key="connection.pool_size">10</prop>  <prop key="current_session_context_class">thread</prop>  <prop key="hibernate.cache.use_second_level_cache">true</prop>  <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>  <prop key="hibernate.cache.use_query_cache">true</prop>  <prop key="hibernate.cache.provider_configuration_file_resource_path">ehcache.xml</prop>  </props> </property> <property name="mappingLocations">   <list>   <value>classpath:ssh/model/User.hbm.xml</value>   </list>  </property>  <!--  <property name="annotatedClasses">  <list>  <value>ssh.model.User</value>  </list> </property> --> </bean>  <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean>  <!-- 事务的传播特性 --> <tx:advice id="txadvice" transaction-manager="transactionManager"> <tx:attributes>  <tx:method name="add*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception"/>  <tx:method name="delete*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception"/>  <tx:method name="update*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception"/>  <tx:method name="save*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception"/> </tx:attributes> </tx:advice>  <aop:config> <aop:pointcut id="pcMethod" expression="execution(* ssh.service..*.*(..))" /> <aop:advisor pointcut-ref="pcMethod" advice-ref="txadvice" /> </aop:config>    <!-- 自定义aop处理 测试 --> <bean id="aopTest" class="ssh.aop.AopTest"></bean> <bean id="myAop" class="ssh.aop.MyAop"></bean> <aop:config proxy-target-class="true"> <aop:aspect ref="myAop">  <aop:pointcut id="pcMethodTest" expression="execution(* ssh.aop.AopTest.test*(..))"/>  <aop:before pointcut-ref="pcMethodTest" method="before"/>  <aop:after pointcut-ref="pcMethodTest" method="after"/> </aop:aspect> </aop:config>  </beans>

springmvc-servlet.xml配置：
配置自动扫描ssh.controller包下的@Controller，这里要恢复applicationContext.xml中配置的exclude-filter；
配置视图解析器，有很多解析器，这里以InternalResourceViewResolver为例；

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd ">  <!-- 启动自动扫描该包下所有的Bean(例如@Controller) --> <context:component-scan base-package="ssh.controller" > <!-- 恢复父容器设置的 exclude-filter，注意包扫描路径ssh.controller--> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />  </context:component-scan>  <!-- 定义视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix">  <value>/WEB-INF/jsp/</value> </property> <property name="suffix">  <value>.jsp</value> </property> </bean> </beans>

编写controller：
由于使用spring mvc替换struts2，也就没有了action包了，删除，并新建controller包，在包下新建UserController类;
@RequestMapping：映射url；
@ResponseBody：内容直接作为body返回；

UserController.java

package ssh.controller;import java.io.PrintWriter;import java.util.List;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.log4j.Logger;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import ssh.aop.AopTest;import ssh.model.User;import ssh.service.UserService;import com.google.gson.Gson;@Controller@RequestMapping("/user")public class UserController { Logger logger = Logger.getLogger(UserController.class); @Resource private UserService userService; @Resource private AopTest aopTest;  @RequestMapping(value="/addUser") @ResponseBody public void addUser(HttpServletRequest request, HttpServletResponse response){ PrintWriter out = null; try{  response.setContentType("text/html;charset=UTF-8");  String account = request.getParameter("account");  String name = request.getParameter("name");  String address = request.getParameter("address");   User user = new User();  user.setAccount(account);  user.setAddress(address);  user.setName(name);  userService.add(user);  out = response.getWriter();  out.write(new Gson().toJson("success")); }catch(Exception e){  e.printStackTrace();  logger.error(e.getMessage());  if(out != null)  out.write(new Gson().toJson("fail")); }finally{  out.flush();  out.close(); }  }  @RequestMapping(value="/queryUser") @ResponseBody public void queryAllUser(HttpServletRequest request, HttpServletResponse response){ PrintWriter out = null;  aopTest.test1(); aopTest.test2();  try {  response.setContentType("text/html;charset=UTF-8");   Gson gson = new Gson();  List<User> userList= userService.queryAllUser();  String gsonStr = gson.toJson(userList);    out = response.getWriter();  out.write(gsonStr); } catch (Exception e) {  e.printStackTrace();  logger.error(e.getMessage());  if(out != null)  out.write(new Gson().toJson("fail")); }finally{  out.flush();  out.close(); } }}

三、运行程序
运行程序，添加用户、查询用户功能正常；
另外二级缓存也正常工作，第二次查询已经没有操作数据库了；
