springMVC-servlet.xml配置文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"   xmlns:context="http://www.springframework.org/schema/context"   xmlns:p="http://www.springframework.org/schema/p"   xmlns:mvc="http://www.springframework.org/schema/mvc"   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.xsd        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">      <!-- 注解扫描 -->      <context:component-scan base-package="com.zwk.annotation"/>      <!--使用mvc注解声明  -->      <mvc:annotation-driven/>            <!-- 不使用mvc注解声明则要注入以下两个bean      <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>      <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>       -->      <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/"></property><property name="suffix" value=".jsp"></property></bean></beans>

启用注解的类

import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controller@RequestMapping("/user")public class AnnotationController {@RequestMapping("/addUser") //不限定请求方式/*限定请求方式@RequestMapping(value="/addUser",method=RequestMethod.GET) * * */public String addUser(){return "/WEB-INF/result";}@RequestMapping("/delUser")public String delUser(HttpServletRequest request){System.out.println("________");request.setAttribute("result", "删除用户");return "/WEB-INF/result";}}
