原文 spring3 mvc系列一:架构基本配置(注解版) http://blog.csdn.net/hankaibo/article/details/7238556
小弟新学spring3mvc,大虾请绕道。
开发环境如下:
OS:windows
IDE:Eclipse3.7.2
其中commons-logging-1.1.1.jar是spring日志依赖jar包,jstl-api-1.2.jar与jstl-impl-1.2.jar是Oracle官方的JSTL接口与实现,如果选Apche的也可以。
<?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_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>Spring3mvc</display-name> <!-- 添加spring3控制器及映射规则 --> <servlet> <servlet-name>spring3mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring3mvc</servlet-name> <url-pattern>/app/*</url-pattern> </servlet-mapping> <!-- 默认跳转到根目录下的页面,在这里为index.jsp --> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list>
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" 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 "> <!-- 默认扫描的包路径 --> <context:component-scan base-package="cn.org.spartacus.spring" /> <!-- 添加注解驱动 --> <mvc:annotation-driven /> <!-- 定义跳转的文件的前后缀 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean>
首先,在WEB-INF下新建一个jsp包,与上文中prefix的值相对应;并在包内新建一jsp文件,名字随便,在这里我叫它success.jsp。
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>hello world</title> </head> <body> Hello world! </body> </html>
其次,编写后台代码,包路径一般是公司域名倒写,我这里随便写了,如下:
/** * 项目名称:Spring3mvc demo * Copyright © 2010-2012 spartacus.org.cn All Rights Reserved */ package cn.org.spartacus.spring; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; /** * Description: TODO * @author hankaibo * @date 2012-11-4 * @version v1.0 */ @Controller @RequestMapping("index") public class IndexController { @RequestMapping("helloWorld") public String helloworld() { // return "success"; //跳转到success页面 return "index"; } }
首先编写根目录下的index.jsp页面,并在其内实现跳转,文件内容如下:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>index</title> </head> <body> OK! <c:redirect url="/app/index/helloWorld" /><!-- 用来实现跳转,验证spring成功与否 --> </body> </html>
测试成功,^_^.
