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 {检查此链接以获取更多参考
