使用tk.mybatis.mapper中的insertSelective返回实体类主键 注解配置

@ApiModelProperty(value = "知识树ID    组织ID")
@Id
@Column(name = "`keynote_id`")
@GeneratedValue(strategy = GenerationType.IDENTITY,generator = "JDBC")
private Long keynoteId;

起作用的是这一行 @GeneratedValue(strategy = GenerationType.IDENTITY,generator = "JDBC")
