1、pom.xml导入依赖
<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.2.7.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.2.1-b03</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> </dependencies>
2、maven项目添加web框架
右键选择add...之后选择
3、controller层
public class HelloController implements Controller { public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception{ ModelAndView mv = new ModelAndView(); //封装对象 mv.addObject("msg","hello!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); //封装要跳转的视图，转到hello.jsp mv.setViewName("hello"); return mv; } }
4、类路径下新建springmvc-servlet.xml配置处理器、适配器
<?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"> <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean> <bean id="/hello" class="com.meng.controller.HelloController"/> </beans>
5、在web/WEB-INF/jsp/hello.jsp中添加：
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> ${msg} </body> </html>
6、在tomcat中设置
7、在项目结构中设置
8、点击运行即可，遇到404的可以参照以下建议
