通过配置文件的方式实现一个简单的HelloWorld。
一、新建项目
1、新建动态web项目
2、命名工程springmvc-01
3、勾选"Generate web.
5、新建springmvc配置文件
6、命名配置文件springmvc-servlet.命名规则：<servlet-name>-servlet.
默认路径为：/WEB-INF/springmvc_servlet.7、选择命名空间
8、完成
二、配置文件
1、配置web.<??><web-app ="http://www.w3.org/2001/ ="http://java.sun.com/ xsi:schemaLocation="http://java.sun.com/ id="WebApp_ID" version="3.0"> <!-- The front controller of this Spring Web application, responsible for handling all application requests --> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- Map all requests to the DispatcherServlet for handling --> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping></web-app>
2、配置springmvc-servlet.<??><beans ="http://www.springframework.org/schema/beans" ="http://www.w3.org/2001/ ="http://www.springframework.org/schema/context" ="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd"> <!-- 配置HandlerMapping，根据BeanName找到对应的Controller --> <bean class="org.springframework.web.servlet.mvc.support.ControllerBeanNameHandlerMapping"></bean> <!-- 配置Controller，响应mvc请求 --> <bean name="/mvc" class="com.zhy.controllers.HelloWorldController"></bean> <!-- 配置视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 配置前缀 --> <property name="prefix" value="/WEB-INF/views/"></property> <!-- 配置后缀 --> <property name="suffix" value=".jsp"></property> </bean></beans>
三、编写Controller
package com.zhy.controllers;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 HelloWorldController implements Controller { /* * 通过视图解析器（ViewResolver）得到实际的物理视图 * 视图解析器的解析规则：prefix + viewname + suffix * 结合本实例，视图解析器的解析出来的物理视图为：/WEB-INF/views/helloworld.jsp * */ @Override public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception { // TODO Auto-generated method stub System.out.println("call controller"); return new ModelAndView("helloworld"); }}
四、新建jsp页面
1、新建helloworld.jsp，路径：WEB-INF/views/helloworld.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%><!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=ISO-8859-1"><title>Insert title here</title></head><body> <h1>Hello World!</h1></body></html>
2、新建index.jsp，路径：WEB-INF/index.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%><!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=ISO-8859-1"><title>Insert title here</title></head><body> <a href="mvc">hello world</a></body></html>
3、完成
四、运行
