spring mvc 通过注解方式配置控制器，实现一个控制器多个方法

admin

首先配置web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	
	<servlet>
		<servlet-name>dispatcher</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>1</load-on-startup>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

</web-app>

2、配置springMVC.xml：

<?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:tx="http://www.springframework.org/schema/tx"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-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/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd
	http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

	<!-- 组件扫描 -->
	<context:component-scan base-package="com.app" />
	
	<!-- 类级别注解 -->
	<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
	<!-- 方法级别注解 -->
	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

	<!-- 视图解释类 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!-- 路径 -->
		<property name="prefix" value="/WEB-INF/jsp/" />
		<!-- 后缀 -->
		<property name="suffix" value=".jsp" />
	</bean>

</beans>

3、IndexController.java：

package com.app.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/index")
public class IndexController{
	
	@RequestMapping(value = "/index")
	public ModelAndView index() throws Exception{
		return new ModelAndView("index");
	}
	
	@RequestMapping(value = "/add")
	public ModelAndView add(){
		return new ModelAndView("add");
	}
	
}
