<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.2.0.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> </dependencies>
1、web.xml
<!--1.注册DispatcherServlet--> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--关联一个springmvc的配置文件:【servlet-name】-servlet.xml--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc-servlet.xml</param-value> </init-param> <!--启动级别-1--> <load-on-startup>1</load-on-startup> </servlet> <!--/ 匹配所有的请求；（不包括.jsp）--> <!--/* 匹配所有的请求；（包括.jsp）--> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
2、在resources中新建springmvc-servlet.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!--处理器映射器--> <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> <!--处理器适配器--> <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/> <!--视图解析器:DispatcherServlet给他的ModelAndView--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="InternalResourceViewResolver"> <!--前缀--> <property name="prefix" value="/WEB-INF/jsp/"/> <!--后缀--> <property name="suffix" value=".jsp"/> </bean> </beans>
3、创建controller.java com/wt/controller/HelloControl.java
package com.wt.controller; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.Controller; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class HelloControl implements Controller { public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception { //ModelAndView 模型和视图 ModelAndView mv = new ModelAndView(); //封装对象，放在ModelAndView中。Model mv.addObject("msg","HelloSpringMVC!"); //封装要跳转的视图，放在ModelAndView中 mv.setViewName("hello"); //: /WEB-INF/jsp/hello.jsp return mv; } }
4、在web 下的 WEB-INF 中 新建jsp文件夹，创建hello.jsp
<%-- Created by IntelliJ IDEA. User: Tom Date: 2020/7/19 Time: 19:36 To change this template use File | Settings | File Templates. --%> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>你好</title> </head> <body> ${msg} </body> </html>
5、在 springmvc-servlet.xml 文件中 注入
<!--id url class control类--> <bean id="/hello" class="com.wt.controller.HelloControl"/>
