一、准备工作
开始之前,先参考上一篇: 

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">

 <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;

 </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;
