VM in the small box on the right (plus the following sentence, if the local warehouse does not have a dependent package, crawl it from a distance):

5. Bring these two sentences in pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.7.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
  </parent>

    <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    </dependencies>

6. Build a com package under java, and then build a startup class

package com;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

//三个注解的合并注解
@SpringBootApplication
public class Ling {
    
    
	//主函数启动
    public static void main(String[] args) {
    
    
    	//启动方法
        SpringApplication.run(Ling.class,args);
    }
}
