簡單的Spring MVC經典案例

主題：構建一個基於SpringMVC的HelloWord Web 項目

目的：快速體驗什麼是SpringMVC

方案：

　　1、創建工程，命名：SpringMVC

　　

　　2、導包

　　

　　3、在SRC下添加spring-mvc.xml配置文件

　　　（注意：名字可以隨便取，最好就是看上就知道是什麼）

　　

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
               http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
               http://www.springframework.org/schema/context
               http://www.springframework.org/schema/context/spring-context-4.0.xsd
               http://www.springframework.org/schema/tx
               http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
               http://www.springframework.org/schema/aop
               http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
               http://www.springframework.org/schema/mvc
                http://www.springframework.org/schema/mvc/spring-mvc.xsd">


</beans> 

　　4、在web.xml配置封裝在Spring裡面的servlet--DispatcherServlet前端控制器，並指定spring-mvc.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-appxmlns: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">
<display-name>SpringMVC</display-name>
<servlet>
<servlet-name>SpringMVC</servlet-name>
<!-- DispathcherServlet 前端控制器-->
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<!-- 變量名隨便取-->
<param-name>contextConfigLocation</param-name>
<!-- 指定SpringMVC配置文件名-->
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<!-- load-on-startup等於1，則表示容器啟動就實例化此Servlet-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<!-- 要與上面Servlet的名字對應-->
<servlet-name>SpringMVC</servlet-name>
<!-- 用來匹配客戶端請求-->
<url-pattern>*.action</url-pattern>
</servlet-mapping>
</web-app>

　　5、在spring-mvc.xml中配置 【HandlerMapping組件】------------------作用------>設置客戶端請求與Controller

　　　　　　　　　　　　 【InternalResourceViewResolver組件】--作用------>設置視圖配置

【HelloController】------------------------作用------->測試請求處理

<?xml version="1.0" encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">

<!-- 定義客戶端請求映射關系-->
<!-- HeanlerMapping是Spring核心組件之一-->
<beanid="headlerMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<propertyname="mappings">
<map>
<entrykey="/hello.action">
<value>helloController</value>
</entry>
</map>
</property>
</bean>

<!-- 增加HelloController的Bean-->
<beanid="helloController" class="controller.HelloController" />

<!-- 定義視圖解釋器（Spring核心組件之一）-->
<beanid="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<propertyname="prefix" value="WEB-INF/jsp/"/>
<propertyname="suffix" value=".jsp"/>
</bean>
</beans>

　　6、編寫HelloController【注意：需要實現Controller接口】

package controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class HelloController implements Controller{

@Override
public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
ModelAndView mv= new ModelAndView("hello");
System.out.println("處理hello.action請求");
return mv;
}

}

　　7、在WEB-INF文件夾下新增"jsp"文件夾，並添加hello.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<metahttp-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
歡迎來到Spring的世界！
</body>
</html>

　　8、跑起來吧兄弟們~然後訪問http://localhost/SpringMVC/hello.action，效果如下：
