RT，先贴上entity

@Table("t_district")
@PK({"district_code","district_name_cn"})
public class District extends BaseEntity {
	@Column
	String district_code;
	@Column
	String district_name_cn;
	@Column
	short district_level;
	@Column
	String parent_district_code;
	@Column
	String district_code_path;
	@Column
	String district_name_path;
	@Column
	String zipcode;
}

下面是log
