Spring boot spring JPA存储库未将记录刷新到数据库

我看到repository.save（）作为更新对象的响应，但在数据库中并没有得到反映

我也尝试过使用JPArepository，也尝试过API公开的saveandflush方法，但没有成功

下面是代码和配置的详细信息

使用sql驱动程序和hibernate作为中间件

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=
spring.datasource.url=jdbc:mysql://localhost:3306/ccmBatch?useSSL=false

spring.batch.job.enabled=false
spring.datasource.initialize=false

spring.jpa.open-in-view=false
spring.jpa.hibernate.ddl-auto=create
spring.jpa.generate-ddl=true
spring.jpa.hibernate.use-new-id-generator-mappings=true
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.jpa.hibernate.naming.strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

POJO：

@Entity(name = "jobtracker")
public class JobTracker implements Serializable {
      
    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Column(name = "CCMBATCH")
    String lockVal;
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    long id;
    
    public JobTracker() {
    }

    public long getId() {
        return id;
    }

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

    public String getLockVal() {
        return lockVal;
    }

    public void setLockVal(String lockVal) {
        this.lockVal = lockVal;
    }
    
}

存储库：

@Repository
public interface JobTrackerRepository extends CrudRepository<JobTracker, Long>{
    
}

上面使用的作业对象正在打印正确的更新值

缺少事务处理可能是问题所在。您没有显示代码的所有相关部分。在调用层次结构中是否有一个方法被注释为@Transactional？我尝试在调用方代码中将@Transactional注释添加到方法中，但仍然没有运气更新的值是什么意思？每次都创建一个新条目。您想说它没有存储在数据库中吗？是的，save（）方法返回更新的值，但记录没有存储在数据库中。如果从同一个类中调用

acquireJobExecutionLock

，它也不会工作。
