springmvc快速入门（注解版本）

1）springmvc快速入门（传统版）

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.jar

org.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

@Controller

public 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="loaderman.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hello.action的URL
