1、在myeclipse中新建web项目，右键点击项目选择Myeclipse-->添加sping框架支持
2、在web.xml中添加spring的支持
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>spmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
3、我命的servlet名字为spmvc，所以在web-inf目录下新建spmvc-servlet.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="/hello.do">helloControl</prop> </props> </property> </bean> <bean id="helloControl" class="com.hnhcc.HelloWorld"></bean> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
4、在com.hnhcc包下新建HelloWorld控制器，实现的了Controller接口，至于深入了解Controller，HandlerMapping，ViewResolver，各位看官在实际应用中再去了解吧！这里不多提了
package com.hnhcc; 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 HelloWorld implements Controller { @Override public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception { ModelAndView mav = new ModelAndView("hello"); mav.addObject("message", "Hello World!"); return mav; } }
5、在spmvc-servlet.xml中定义了viewResolver的prefix在根目录，suffix为jsp，我返回的view名为hello，所以在WebRoot新建hello.jsp，将message输出
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>spring mvc</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> </head> <body> ${message } </body> </html>
6、发布到tomcat下运行一下http://localhost:8080/xxx/hello.do试试
