1、新建一个Java Web项目
2、导入jar包
3、在WEB-INF下面建一个hello.jsp页面。
1 <%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%> 2 3 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 4 <html> 5 <head> 6<title>My JSP 'hello.jsp' starting page</title> 7 </head> 8 9 <body>10hello springmvc11 </body>12 </html>
4、配置web.xml文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="/2001/XMLSchema-instance" xmlns="/xml/ns/javaee" xsi:schemaLocation="/xml/ns/javaee /xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> 3 4<servlet> 5 <servlet-name>dispatcherServlet</servlet-name> 6 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 7 <init-param> 8 <param-name>contextConfigLocation</param-name> 9 <param-value>classpath:spring-mvc.xml</param-value>10 </init-param>11 <load-on-startup>1</load-on-startup>12</servlet>1314<servlet-mapping>15 <servlet-name>dispatcherServlet</servlet-name>16 <url-pattern>/</url-pattern>17</servlet-mapping>1819<welcome-file-list>20 <welcome-file>index.jsp</welcome-file>21</welcome-file-list>22 </web-app>
5、配置spring-mvc.xml文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="/schema/beans" 3xmlns:xsi="/2001/XMLSchema-instance" 4xmlns:context="/schema/context" 5xsi:schemaLocation="/schema/beans /schema/beans/spring-beans-4.3.xsd 6 /schema/context /schema/context/spring-context-4.3.xsd"> 7 8<context:component-scan base-package="com.proc"></context:component-scan> 9 10<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">11 <property name="prefix" value="/WEB-INF/"/>12 <property name="suffix" value=".jsp"></property>13</bean>14 </beans>
InternalResourceViewResolver：视图解析器。根据Url地址遭到找到文件资源
prefix：前缀
suffix:后缀
6、配置控制器
1 package com.proc; 2 3 import org.springframework.stereotype.Controller; 4 import org.springframework.web.bind.annotation.RequestMapping; 5 6 @Controller 7 public class Hello { 8 9@RequestMapping("/hello")10public String hello(){11 System.out.println("hello springmvc");12 return "hello";13}14 }
@RequetMapping注解作用是url映射
测试访问
