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OGOgA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；

SSH

contextConfigLocation

classpath:applicationContext.xml

org.springframework.web.context.ContextLoaderListener

index.jsp

springmvc

org.springframework.web.servlet.DispatcherServlet

contextConfigLocation

classpath:springmvc-servlet.xml

1

springmvc

*.do

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；

xmlns:mvc="http://springframework.org/schema/mvc"

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 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；
