spring data jpa 自动保存更新插入时间

新建BaseEntity,@MappedSuperclass @EntityListeners(AuditingEntityListener.class)很重要

@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public class BaseEntity {

    private static Gson gson = new Gson();

    @Id
    @GeneratedValue
    private Long id;

    @CreatedDate
    private Date createDate;

    @LastModifiedDate
    private Date updateDate;

    public Date getCreateDate() {
        return createDate;
    }
    public Date getUpdateDate() {
        return updateDate;
    }
    public void setCreateDate(Date createDate) {
        this.createDate = createDate;
    }
    public void setUpdateDate(Date updateDate) {
        this.updateDate = updateDate;
    }
    @Override
    public String toString() {
        return gson.toJson(this);
    }
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
}

其他Entity继承BaseEntity

@Entity
public class User extends BaseEntity

启动类加@EnableJpaAuditing
