spring MVC 环境搭建

　绿色版Spring MVC（单纯的springMVC）

　　一、导包，为了获取请求数据多添加一个包

　　二、web.xml配置

<?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_2_5.xsd"

         id="WebApp_ID" version="2.5">

  <!-- 这就是一个名字 -->

  <display-name>webSpringMVC</display-name>

  <!-- 加载spring容器 -->

  <!-- 初始化参数-->

  <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>/WEB-INF/classes/applicationContext.xml</param-value>

  </context-param>

  <!-- 监听 -->

  <listener>

    <listener-class>

            org.springframework.web.context.ContextLoaderListener

        </listener-class>

  </listener>

  <!-- springmvc前端控制器 -->

  <servlet>

    <servlet-name>dispatcherServlet</servlet-name>

    <servlet-class>

            org.springframework.web.servlet.DispatcherServlet

        </servlet-class>

    <init-param>

      <param-name>contextConfigLocation</param-name>

      <param-value>/WEB-INF/classes/springMvc.xml</param-value>

    </init-param>

    <load-on-startup></load-on-startup>

  </servlet>

  <servlet-mapping>

    <servlet-name>dispatcherServlet</servlet-name>

    <url-pattern>*.action</url-pattern>

  </servlet-mapping>

  <!-- 配置过滤器 -->

  <!-- post乱码过虑器 -->

  <filter>

    <filter-name>CharacterEncodingFilter</filter-name>

    <filter-class>

            org.springframework.web.filter.CharacterEncodingFilter

        </filter-class>

    <init-param>

      <param-name>encoding</param-name>

      <param-value>utf-</param-value>

    </init-param>

    <init-param>

      <param-name>forceEncoding</param-name>

      <param-value>true</param-value>

    </init-param>

  </filter>

  <filter-mapping>

    <filter-name>CharacterEncodingFilter</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

  <!-- 首页 -->

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

  <!-- session超时 -->

  <!--分钟为单位

      设置为0，-1 表示永不超时 -->

  <session-config>

    <session-timeout>30</session-timeout>

  </session-config>

</web-app>

　　三、springMvc.xml配置

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

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

       xmlns:p="http://www.springframework.org/schema/p"

       xmlns:context="http://www.springframework.org/schema/context"

       xmlns:aop="http://www.springframework.org/schema/aop"

       xmlns:tx="http://www.springframework.org/schema/tx"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

            http://www.springframework.org/schema/context

            http://www.springframework.org/schema/context/spring-context-3.0.xsd

            http://www.springframework.org/schema/aop

            http://www.springframework.org/schema/aop/spring-aop-3.0.xsd

            http://www.springframework.org/schema/tx

            http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

            http://www.springframework.org/schema/mvc

            http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd

            http://www.springframework.org/schema/context

            http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<!-- 启用 spring 注解 -->

<context:component-scan base-package="test" />

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>

<!-- prefix和suffix：查找视图页面的前缀和后缀（前缀[逻辑视图名]后缀）

    比如传进来的逻辑视图名为hello，则该该jsp视图页面应该存放在“WEB-INF/jsp/hello.jsp” -->

<bean

    class="org.springframework.web.servlet.view.InternalResourceViewResolver">

    <property name="prefix" value="/jsp/" />

    <property name="suffix" value=".jsp" />

</bean>

</beans>

　　四、applicationContext.xml

　　即使没有内容也要配置，否则不能运行。

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

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

       xmlns:p="http://www.springframework.org/schema/p"

       xmlns:context="http://www.springframework.org/schema/context"

       xmlns:aop="http://www.springframework.org/schema/aop"

       xmlns:tx="http://www.springframework.org/schema/tx"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

            http://www.springframework.org/schema/context

            http://www.springframework.org/schema/context/spring-context-3.0.xsd

            http://www.springframework.org/schema/aop

            http://www.springframework.org/schema/aop/spring-aop-3.0.xsd

            http://www.springframework.org/schema/tx

            http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

            http://www.springframework.org/schema/mvc

            http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd

            http://www.springframework.org/schema/context

            http://www.springframework.org/schema/context/spring-context-3.0.xsd">

</beans>

　　四、hello.jsp

<%@ page language="java" pageEncoding="UTF-8"%>

<html>

<head>

<title>SpringMVC</title>

</head>

<body>

您好，${user }!

</body>

</html>

　　五、Controller

package test;

import java.util.Date;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

@Controller

//可以配置也可以不配 多一级目录

//@RequestMapping("/hello")

public class HelloController{

    @SuppressWarnings("deprecation")

    public ModelAndView handleRequest(HttpServletRequest request,

            HttpServletResponse response) {

        ModelAndView mv = new ModelAndView();

        // 添加模型数据 可以是任意的POJO对象

        mv.addObject("user", request.getParameter("user") + "-->" + new Date().toLocaleString());

        // 设置逻辑视图名，视图解析器会根据该名字解析到具体的视图页面

        mv.setViewName("hello");

        return mv;

    }

    @SuppressWarnings("deprecation")

    @RequestMapping("/hello")

    public String hello(HttpServletRequest request,HttpServletResponse response){

        request.setAttribute("user", request.getParameter("user") + "-->" + new Date().toLocaleString());

        return "hello";

    }

}

　　六、tomcat部署好后访问地址

 http://localhost:8080/springMvc/hello.action?user=SpringMMM
