1.必要なswagger 2の依存
		<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.7.0</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.7.0</version>
        </dependency>

2.構成クラスを自分で作成する必要がある
@Configuration
public class WebConfig implements WebMvcConfigurer {

 //    
 @Bean
 public WebMvcConfigurer corsConfigurer() {
     return new WebMvcConfigurer() {
         @Override
         //                
         public void addCorsMappings(CorsRegistry registry) {
             //      
             registry.addMapping("/**")
                     //       
                     .allowedOrigins("*")
                     //    Cookie  
                     .allowCredentials(true)
                     //       (    )
                     .allowedMethods("GET", "POST", "PUT", "DELETE")
                     //       (    )
                     .allowedHeaders("*")
                     //        (                  )
                     .exposedHeaders("Header1", "Header2");
         }
     };
 }

@Configuration
@EnableSwagger2
public class SwaggerConfig {
 @Bean
 public Docket createRestApi() {
     return new Docket(DocumentationType.SWAGGER_2)
             .apiInfo(apiInfo())
             .select()
             .apis(RequestHandlerSelectors.basePackage("com.zzq.sprintboot_vue.controller"))
             .paths(PathSelectors.any())
             .build();
 }

 private ApiInfo apiInfo() {
     return new ApiInfoBuilder()
             .title("Spring Boot   Swagger2         ")
             .description("                    Demo")
             .termsOfServiceUrl("https://blog.csdn.net/ca1993422")
             .contact("   ")
             .version("1.0")
             .build();
 }

3.プログラム入口に注記@EnableSwagger 2を記入してください
@SpringBootApplication
@EnableSwagger2
public class SprintbootVueApplication {

 public static void main(String[] args) {
     SpringApplication.run(SprintbootVueApplication.class, args);
 }

@Bean
 public IdWorker getIdWorker(){
     return  new IdWorker();
 }
}

エンティティークラス
package com.zzq.sprintboot_vue.pojo;

import lombok.Data;

import javax.persistence.*;

@Data
@Table(name = "student3")
@Entity
public class Student2 {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
   private  Integer stuid;
   private  String name;
   private  String sex;

    private  Integer gradeId;

}


4.プライマリ・キーidの作成にクラスを追加できます(雪...名前を忘れました)
package com.zzq.springdatajpa02.util;

import java.lang.management.ManagementFactory;
import java.net.InetAddress;
import java.net.NetworkInterface;
