springmvc注解事例

注解有简化，灵活性增强的功能

1.引入jar包

com.springsource.javax.validation-1.0.0.GA.jar
com.springsource.org.aopalliance-1.0.0.jar
com.springsource.org.apache.commons.logging-1.1.1.jar
commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
hibernate-validator-4.1.0.Final.jar
log4j.jar
slf4j-api-1.5.8.jar
slf4j-log4j12.jar
spring-aop-3.2.2.jar
spring-aspects-3.2.2.jar
spring-beans-3.2.2.jar
spring-context-3.2.2.jar
spring-context-support-3.2.2.jar

maven pom.xml如下

2.web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

3.spring-mvc.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:mvc="http://www.springframework.org/schema/mvc"

    xmlns:context="http://www.springframework.org/schema/context"

    xsi:schemaLocation="http://www.springframework.org/schema/beans

            http://www.springframework.org/schema/beans/spring-beans-3.2.xsd

            http://www.springframework.org/schema/mvc

            http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd

            http://www.springframework.org/schema/context

            http://www.springframework.org/schema/context/spring-context-3.2.xsd ">

        <!-- 自动扫描注解 -->

    <context:component-scan base-package="com.shanheyongmu.controller"/>

    <!-- 注解驱动 -->

    <mvc:annotation-driven/>

    <!-- 内部资源视图解析器  prefix + logicName + suffix /WEB-INF/jsps/ + index + .jsp-->

<!--     用于解析在controller 中return  ModelAndView中的视图名的拼凑 -->

    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <!-- 前缀 -->

        <property name="prefix" value="/WEB-INF/jsps/"/>

        <!-- 后缀 -->

        <property name="suffix" value=".jsp"/>

    </bean>

</beans>

3.controller.java

package com.shanheyongmu.controller;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.mvc.AbstractController;

//这里声明是注解

@Controller

public class HomeController extends AbstractController {

    //这里声明访问路径

    @RequestMapping(value={"/home.action","/aa.action"})

    @Override

    protected ModelAndView handleRequestInternal(HttpServletRequest request,

            HttpServletResponse response) throws Exception {

        System.out.println("hello" + request.getContextPath() + request.getServletPath());

        return new ModelAndView("index");

    }

}

这样就可以通过localhost:8080/项目名/aa.action 或者后面是home.action进行访问了
