一、添加 Maven 依赖
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.1.5.RELEASE</version>
</dependency>
二、创建 web.xml 配置文件
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<servlet>
<!-- 配置 Spring MVC 核心控制器 -->
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 配置 Spring MVC 核心控制器的参数，读取 Spring MVC 配置文件 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:SpringMVC.xml</param-value>
</init-param>
</servlet>
<!-- 配置 Spring MVC 核心控制器拦截哪些请求 URL -->
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
三、创建 Spring MVC 配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
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
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 配置 spring 容器要扫描的包 -->
<context:component-scan base-package="chu.yi.bo"/>
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
四、创建 Controller
@Controller("helloController")
public class HelloController {
@RequestMapping("/hello")
public String sayHello() {
System.out.println("Hello World!");
return "success";
}
}
五、创建结果视图
success.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<div>这是成功界面！</div>
</body>
</html>
