使用spring 2.5.6搭建mvc框架

1. Project Dependency
spring 2.5.6所有包： spring 2.5.6 全集下载
commons-logging⑴.1.3.jar: commons-logging⑴.1.3下载
2. Controller & Mapping
从2.5开始，spring开始支持@RequestMapping标注，可对符合的url路径进行辨别。
HelloWorldController.java:
package controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/welcome")
public class HelloWorldController {
@RequestMapping(method=RequestMethod.GET)
public String helloWord(ModelMap model){
System.out.println("hahaha ,nimeiyoushuozhimakaimen");
model.addAttribute("message","fuck YOU@!!!");
return "HelloWorldPage";
}
}
3. Spring Configuration
当该xml被加载以后，能够打开“注解扫描功能”，并定义InternalResourceViewResolver映照规则，将controller中返回的内容映照为前端内容。
mvc-dispatcher-servlet.xml：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans⑵.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context⑵.5.xsd">
<context:component-scan base-package="controller" />
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name="prefix">
<value>WEB-INF/pages/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>
4. Integrate Web application with Spring
网站
服务器server在加载web.xml的时候首先定义欢迎界面（默许：index2.jsp,注意路径的写法），声明ContextLoadListener和DispatcherServlet，和servlet映照规则。
web.xml：
<web-app id="WebApp_ID" 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">
<display-name>mySpringwork</display-name>
<welcome-file-list>
<welcome-file>/WEB-INF/index2.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
5. JSP Views
HelloWorldPage.jsp：
<%@ page language="java" contentType="text/html; charset=ISO⑻859⑴"
pageEncoding="ISO⑻859⑴"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO⑻859⑴">
<title>Insert title here</title>
</head>
<body>
<h1>Message : ${message}</h1>
<h2>${msg}</h2>
</body>
</html>
