Question

我在使用Spring Boot和Hibernate时遇到问题。我在mysql表中有一个实体。当我单独致电服务时，一切正常。但是，当我使用jmeter之类的负载测试运行此程序时，出现以下错误：

org.hibernate.HibernateException: identifier of an instance of com.kafka.adapter.entity.TransactionEntity was altered from 4820 to 4821

我尝试了多种方法来获取无法成功的主键：

application.yml
server:
  port: 9027
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/test?useSSL=false&allowPublicKeyRetrieval=true
    username: --
    password: --
    driver-class-name: com.mysql.cj.jdbc.Driver
    tomcat:
      test-while-idle: true
      validation-query: SELECT 1
    initialization-mode: never
    platform: mysql
  jpa:
    properties:
      hibernate:
        dialect: org.hibernate.dialect.MySQL5Dialect
    hibernate:
      naming:
        physical-strategy: org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy
      ddl-auto: validate

TransactionEntity：

    @Entity
    @Table(name = "transactions")
    public class TransactionEntity {

        @Id
        @GeneratedValue(
                strategy= GenerationType.AUTO,
                generator="native"
            )
            @GenericGenerator(
                name = "native",
                strategy = "native"
            )
        private Long id;
        private String hogan_co;


    public Long getId() {
            return id;
        }

        public void setId(Long ID) {
            this.id = ID;
        }

    Service class
    public void transactionTranslation2() {
            startTimeDuration = System.currentTimeMillis();

            transactionRepository.save(te);
            endTimeDuration = System.currentTimeMillis();

        }

    public void findCategory() {

    te = new TransactionEntity();
            transactionTranslation2();
            duration = endTimeDuration - startTimeDuration;
    // System.out.println(duration * 0.001 + " seconds");

        }

我期望每小时超过100万笔交易，因此它需要处理高负载。你能帮我吗？
