下面是一个完整的 Spring MVC + JSP 项目的配置流程，适合传统 Java Web 项目开发

🏗️ 项目结构概览

springmvc-jsp-demo/
├── src/
│   ├── main/
│   │   ├── java/
│   │   │   └── com.example.controller/
│   │   │       └── HomeController.java
│   │   ├── resources/
│   │   └── webapp/
│   │       ├── WEB-INF/
│   │       │   ├── views/
│   │       │   │   └── home.jsp
│   │       │   └── web.xml
├── pom.xml

⚙️ Maven 配置（`pom.xml`）

确保使用 war 打包方式，并添加 Spring MVC 依赖：

<packaging>war</packaging><dependencies><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.3.30</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>4.0.1</version><scope>provided</scope></dependency>
</dependencies>

🧩 web.xml 配置（注册 DispatcherServlet）

<web-app><servlet><servlet-name>dispatcher</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/dispatcher-servlet.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>dispatcher</servlet-name><url-pattern>/</url-pattern></servlet-mapping>
</web-app>

🧠 Spring 配置文件（`dispatcher-servlet.xml`）

配置视图解析器和组件扫描：

<beans xmlns="http://www.springframework.org/schema/beans"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.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"><context:component-scan base-package="com.example.controller" /><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/views/" /><property name="suffix" value=".jsp" /></bean>
</beans>

🧾 控制器类（`HomeController.java`）

package com.example.controller;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;@Controller
public class HomeController {@RequestMapping("/")public String home() {return "home"; // 对应 /WEB-INF/views/home.jsp}
}

🖼️ JSP 页面（`home.jsp`）

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>Spring MVC + JSP Demo</title>
</head>
<body><h1>Hello, Spring MVC + JSP!</h1>
</body>
</html>
