<dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.2.10.RELEASE</version> </dependency>
3)创建controller包 创建一个HelloController.java @Controller 注解方式在IOC容器创建bean @RequestMapping("/hello")注解映射请求路径 RequestMapping注解使用参考文章https://blog.csdn.net/zalan01408980/article/details/82904126
package com.zb.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloController {
@RequestMapping("/hello")
public String haha(){
System.out.println("Controller");
//指定到WEB-INF/jsp下的success.jsp文件
return "success";
}
}
4)创建resource包创建一个spring-mvc.xml配置文件 配置组件扫描 指定要扫描的包 包里的所有已经注解的类和方法都会被在IOC容器内创建bean对象 视图解析器 参考文章：https://blog.csdn.net/weixin_40277684/article/details/100596257
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="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 https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 组件扫描 扫描注解-->
<context:component-scan base-package="com.zb.controller"/>
<!-- 视图解析器 resourceView 在Controller注解的类的方法中收到返回值
再将返回值与前缀prefix的值WEB-INF/jsp/拼接
与suffix的值.jsp拼接
-->
<bean id="resourceView" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
<mvc:annotation-driven/>
</beans>
5）配置web.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd">
<servlet>
<!--dispatcherServlet前置控制器 MVC C层核心控制器-->
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<!-- dipatcherServlet加载springIOC容器-->
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<!--1指在web容器加载时 就加载dispatcherServlet-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<!--/ 表示dispatcherServlet拦截所有用户请求url 除了后缀为.jsp的文件url-->
<!-- /* 表示拦截所有文件url-->
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
6）创建View视图层（即jsp） 创建 WEB-INF/jsp/success.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>success</title>
</head>
<body>
<h1>hello world!!!!haha</h1>
</body>
</html>
index.jsp
<html> <body> <a href="hello"> <h2>Hello World!</h2></a> </body> </html>
7)部署tomcat服务器 测试
