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"?>

<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">

<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;

</aop:aspect>

</aop:config>

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;
