第一个自己配的springMVC入门程序

浏览数：41 / 时间：2015年06月08日

以前在公司用SpringMVC开发一直不知道怎么配置，感觉spring配置真是糟糕透了，现在终于试着自己去学点东西。这是在MKYONG里面的范例，自己试着去跑了下。

先说下项目结构

要加载与spring相关的包

HelloController.java（注意是在包controller下）

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
public class HelloController {

	@RequestMapping(value="/welcome",method = RequestMethod.GET)
	public String printWelcome(ModelMap model) {

		model.addAttribute("message", "Spring 3 MVC Hello World");
		return "hello";

	}
	
}

hello.jsp（注意是放在WEB-INF下的pages目录下）　

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!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=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
	<h1>Message : ${message}</h1>	
</body>
</html>

mvc-dispatcher-xml （注意：可以放置在src目录下，但是一般是放置在WEB-INF目录下）　

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	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">
 
	<context:component-scan base-package="controller" />
 
	<bean
		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>

web.xml（放置在WEB-INF，目录下）

<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>Spring MVC Application</display-name>
 
	<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>

index.jsp

============这个可以里面什么都不用写==========最后启动tomcat服务器，在url中输入 localhost:8080/spring/welcome

结果
