1.创建一个maven的Module
2.参照标准SpringBoot工程的pom文件，书写自己的pom文件即可
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <!--引入springBoot--> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.6.7</version> </parent> <groupId>org.example</groupId> <artifactId>springboot03</artifactId> <version>1.0-SNAPSHOT</version> <!--引入web依赖--> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> </project>
3.写启动类与HelloController
（1）启动类在包com.xxx下
（2）HelloController类在包com.xxx.controller下
4.测试结果
右键单击启动类
选择运行启动类
启动成功
浏览器输入http://localhost:8080/hello
