spring mvc4.1.6 spring4.1.6 hibernate4.3.11 mysql5.5.25开发环境搭建图文教程

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"?>

 </listener>

 </welcome-file-list>

 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

  <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；

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；
