spring mvc4.1.6 + spring4.1.6 + hibernate4.3.11 + mysql5.5.25 开发环境搭建及相关说明

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

struts2.3.24 + spring4.1.6 + hibernate4.3.11 + mysql5.5.25 开发环境搭建及相关说明

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；

  <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；

    </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；
