spring4 mvc HelloWorld

一、下载spring-framework-4.0.0.M3-dist

下载地址：http://www.springsource.org/spring-community-download

二、解压

将spring-framework-4.0.0.M3-dist.zip文件解压，拷贝相关文件至发布目录的lib下如图：

三、web.xml配制

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

   <servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 可以自定义servlet.xml配置文件的位置和名称，默认为WEB-INF目录下，名称为[<servlet-name>]-servlet.xml，如spring-servlet.xml
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring-servlet.xml</param-value>  默认
    </init-param>
        -->
        <load-on-startup>1</load-on-startup>
    </servlet>
     
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/*.do</url-pattern>
    </servlet-mapping>
      
     
     <filter>
        <filter-name>encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/</url-pattern>
    </filter-mapping>

    <!-- Spring配置 -->
    <!-- ====================================== -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
      
     
    <!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:config/applicationContext.xml</param-value>
    </context-param>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

</web-app>

四、applicationContext.xml文件配制

<?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: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-2.5.xsd
                http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
                http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
         </beans>

五、spring-servlet.xml配制

 

<?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:p="http://www.springframework.org/schema/p"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
              <bean class="org.springframework.http.converter.StringHttpMessageConverter">
        <property name="supportedMediaTypes" value = "text/plain;charset=UTF-8" />
        </bean>
        </mvc:message-converters>
</mvc:annotation-driven>
    <context:component-scan base-package="net.spring.controller"/>
     <!-- 视图解释类 --> 
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
        <property name="prefix" value="/WEB-INF/jsp/"/> 
        <property name="suffix" value=".jsp"/><!--可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑  --> 
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> 
    </bean> 
</beans>

 

六、java示例

package net.spring.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
 
    @Controller
    public class HelloWorldController {

        @RequestMapping("/helloWorld")
        public String helloWorld(Model model) {
            model.addAttribute("message", "中国");
            return "helloWorld";
        }
    }

 

七、helloWorld.jsp文件放至\WEB-INF\jsp\目录下

 

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
     <title>Spring 3.0 MVC demo</title>
    </head>
    <body>
     <a href="hello.do">Say Hello</a> ${message}
    </body>
    </html>

 

八、运行helloWorld.do显示如下

 完成
