1）springmvc快速入门（传统版）

@Controller：表示当前类是控制类

@RequestMapping(value="/hello")只能方法的访问映射地址，可以省略.action

步一：创建springmvc-day02这么一个web应用

步二：导入springioc，springweb和springmvc相关的jar包

------------------------------------------------------springWEB模块   org.springframework.web-3.0.5.RELEASE.jarorg.springframework.web.servlet-3.0.5.RELEASE.jar（mvc专用）   ------------------------------------------------------springIOC模块   org.springframework.asm-3.0.5.RELEASE.jar   org.springframework.beans-3.0.5.RELEASE.jar   org.springframework.context-3.0.5.RELEASE.jar   org.springframework.core-3.0.5.RELEASE.jar   org.springframework.expression-3.0.5.RELEASE.jar

步三：在/WEB-INF/下创建web.xml文件

<servlet><servlet-name>DispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>DispatcherServlet</servlet-name><url-pattern>*.action</url-pattern></servlet-mapping>

步四：创建HelloAction.java控制器类

@Controllerpublic class HelloAction{@RequestMapping(value="/hello")public String helloMethod(Model model) throws Exception{System.out.println("HelloAction::helloMethod()");model.addAttribute("message","这是我的第二个springmvc应用程序");return "/success.jsp";}}

步五：在/WebRoot/下创建success.jsp

<%@ page language="java" pageEncoding="UTF-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <title>这是我的第二个springmvc应用程序</title>  </head>  <body>success.jsp<br/>${message}  </body></html>

步六：在/src/目录下创建spring.xml配置文件

<?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:context="http://www.springframework.org/schema/context"      xmlns:aop="http://www.springframework.org/schema/aop"      xmlns:tx="http://www.springframework.org/schema/tx"  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/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              ">   <!-- Action控制器 -->  <context:component-scan base-package="cn.lfsenior.javaee.springmvc.helloannotation"/>                     <!-- 基于注解的映射器(可选) -->      <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>            <!-- 基于注解的适配器(可选) -->      <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>            <!-- 视图解析器(可选) -->      <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"/>      </beans>

步七：部署web应用到tomcat中，通过浏览器访问如下URL：

http://127.0.0.1:8080/springmvc-day02/hello.action
