主题:构建一个基于SpringMVC的HelloWord Web 项目
目的:快速体验什么是SpringMVC
方案:
1、创建工程,命名:SpringMVC
2、导包
3、在SRC下添加spring-mvc.
(注意:名字可以随便取,最好就是看上就知道是什么)
<??><beans ="http://www.springframework.org/schema/beans" ="http://www.springframework.org/schema/mvc" ="http://www.w3.org/2001/ ="http://www.springframework.org/schema/context" ="http://www.springframework.org/schema/tx" ="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"></beans>
4、在web.
<??><web-app ="http://www.w3.org/2001/ ="http://java.sun.com/ xsi:schemaLocation="http://java.sun.com/ id="WebApp_ID" version="2.5"> <display-name>SpringMVC</display-name> <servlet> <servlet-name>SpringMVC</servlet-name> <!-- DispathcherServlet 前端控制器 --> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <!-- 变量名随便取 --> <param-name>contextConfigLocation</param-name> <!-- 指定SpringMVC配置文件名 --> <param-value>classpath:spring-mvc.</param-value> </init-param> <!-- load-on-startup等于1,则表示容器启动就实例化此Servlet --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <!-- 要与上面Servlet的名字对应 --> <servlet-name>SpringMVC</servlet-name> <!-- 用来匹配客户端请求 --> <url-pattern>*.action</url-pattern> </servlet-mapping></web-app>
5、在spring-mvc.
【InternalResourceViewResolver组件】--作用------>设置视图配置
【HelloController】------------------------作用------->测试请求处理
<??><beans ="http://www.springframework.org/schema/beans" ="http://www.springframework.org/schema/mvc" ="http://www.w3.org/2001/ ="http://www.springframework.org/schema/context" ="http://www.springframework.org/schema/tx" ="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 定义客户端请求映射关系 --> <!-- HeanlerMapping是Spring核心组件之一 --> <bean id="headlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <map> <entry key="/hello.action"> <value>helloController</value> </entry> </map> </property> </bean> <!-- 增加HelloController的Bean --> <bean id="helloController" class="controller.HelloController" /> <!-- 定义视图解释器(Spring核心组件之一) --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean></beans>
6、编写HelloController【注意:需要实现Controller接口】
package controller;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;public class HelloController implements Controller{ @Override public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception { ModelAndView mv = new ModelAndView("hello"); System.out.println("处理hello.action请求"); return mv; } }
7、在WEB-INF文件夹下新增"jsp"文件夹,并添加hello.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>Insert title here</title></head><body> 欢迎来到Spring的世界!</body></html>
8、跑起来吧兄弟们~然后访问http://localhost/SpringMVC/hello.action,效果如下:
