【JAVA Web】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

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

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">

<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；

<?xml version="1.0" encoding="UTF-8"?>

</aop:aspect>
</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；
