3.applicationContext.xml文件的配置

<?xml version="1.0"encoding="UTF-8"?><beansxmlns="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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><!--配置Spring所要扫描的注解 @Controller注解交给SpringMVC来处理 Spring不处理--><context:component-scanbase-package="com.star.*"><context:exclude-filtertype="annotation"expression="org.springframework.stereotype.Controller"/></context:component-scan></beans>

4.配置SpringMVC的dispatcher-servlet.xml文件的配置

<?xml version="1.0"encoding="UTF-8"?><beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd"><!--配置仅扫描Controller注解的类 默认为都扫描需要吧 use-default-filters设置为false--><context:component-scanbase-package="com.star.*"use-default-filters="false"><context:include-filtertype="annotation"expression="org.springframework.stereotype.Controller"/></context:component-scan><!--配置Spring MVC的视图解析器--><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><!--前缀--><propertyname="prefix"value="/WEB-INF/"/><!--后缀--><propertyname="suffix"value=".jsp"/></bean><mvc:annotation-driven/></beans>

5.配置action类 TestHandlber.java

<pre name="code" class="java">package com.star.Handlber;import org.apache.log4j.Logger;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;/** * Created by Star on 2016/9/16. * * @author star * @version 1.0 */@Controller@RequestMapping("/login")public class TestHandlber {    @RequestMapping("/login")    public String login(@RequestParam(value = "username",required = false)String username){        //获取Logger对象        Logger logger = Logger.getRootLogger();        logger.info("开始验证用户名！");        if(username.equals("admin")){            logger.info("登陆成功！用户名为："+username+"--重定向到success.jsp页面");            return "success";        }else {            logger.info("登陆失败！用户名不正确！跳转到error页面！");            return "error";        }    }}
