我认为最好的选择是EntityListener使用@PrePersist和@PreUpdate注释，为实体侦听器创建配置，然后您将可以访问要保存的每个实例，每次尝试使用以下方法持久化或更新内容时都会调用此方法hibernate或spring数据存储库
public class EntityToPersistListener{
@PrePersist
@PreUpdate
public void methodExecuteBeforeSave(final EntityToPersist reference) {
//Make any change to the entity such as calculation before the save process
reference.setAmount(xxxx)
}
}
您只需要在实体bean上方添加注释
@Entity
@Table(name = "", schema = "", catalog = "")
@EntityListeners(EntityToPersistListener.class)
public class EntityToPersist implements Serializable {
