添加如下：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.9.RELEASE</version>
    </parent>
    
    
    <dependencies>
        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

添加后如下：

<?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">

            </dependency>
        </dependencies>
    
        <properties>
            <maven.compiler.source>8</maven.compiler.source>

        </properties>
    
    </project>

修改了下目录：

package com.bulunzhihao;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class MainApplication
    {
        public static void main(String[] args)
        {
            SpringApplication.run(MainApplication.class, args);
        }
    
    }

package com.bulunzhihao.web;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class StartMainController
    {
        @RequestMapping("/123")
        public String home()
        {
            return "hello-2022.04.04----123";
        }
    
    }
