1）springmvc快速入門（傳統版）
步一：建立springmvc-day02這麼一個web應用
步二：匯入springioc，springweb和springmvc相關的jar包
------------------------------------------------------springWEB模組 org.springframework.web-3.0.5.RELEASE.jar org.springframework.web.servlet-3.0.5.RELEASE.jar（mvc專用） ------------------------------------------------------springIOC模組 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/下建立web.xml檔案
<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：建立HelloAction.java控制器類
@Controller public class HelloAction{ @RequestMapping(value="/hello") public String helloMethod(Model model) throws Exception{ System.out.println("HelloAction::helloMethod()"); model.addAttribute("message","這是我的第二個springmvc應用程式"); return "/success.jsp"; } }
步五：在/WebRoot/下建立success.jsp
<%@ page language="java" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>這是我的第二個springmvc應用程式</title> </head> <body> success.jsp<br/> ${message} </body> </html>
步六：在/src/目錄下建立spring.xml配置檔案
<?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"/> <!-- 基於註解的對映器(可選) --> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> <!-- 基於註解的介面卡(可選) --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> <!-- 檢視解析器(可選) --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"/> </beans>
步七：部署web應用到tomcat中，通過瀏覽器訪問hello.action的URL
