我有一个名为RoomDetailDto的DTO课程,如下所示
public class RoomDetailDto {
String ID;
@NotEmpty
String cd;
@NotEmpty
String name;
String dscp;
RoomCategoryDto roomCategoryDto;
//setter and getter
roomCategoryDto 引用另一个名为RoomCategoryDto的DTO,如下所示:
public class RoomCategoryDto {
String ID;
@NotEmpty
@Length(min = 0, max = 5)
String cd;
@NotEmpty
String name;
@NotEmpty
@NumberValue
String cost;
String dscp;
//setter and getter
我发送给服务器的这个JSON
{ “CD”: “dfs23” “名”:“df223” “DSCP”: “sfdsfs” “roomCategoryDto”:{ “CD”: “KLS2” “名字”:“Kelas 2”, “成本”: “200000”, “DSCP”:空, “ID”: “7f554d7a-3c5d-4c15-921d-fa4b4c629e6c” } }
发送到服务器后,该记录已成功插入,但 roomCategoryDto 'NULL'
任何人都可以建议吗? 请找到我的控制器如下:{ “cd”:“dfs23”, “名字”:“df223”, “dscp”:“sfdsfs”, “roomCategoryDto”:null, “id”:“ed22b38d-2bc3-4c80-b035-8936318c90c7” }
@RequestMapping(value = "/updateAction", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public RoomDetailDto update(@Validated @RequestBody RoomDetailDto data) throws ParseException, RecordNotFoundException, java.text.ParseException {
logger.info("add");
RoomDetailEntity add = roomDetailService.updateRoomDetail(convertToEntity(data));
return convertToDto(add);
}
和我的实体如下
@Entity(name = "RoomCategoryEntity") @Table(name = "t_room_category") public class RoomCategoryEntity implements Serializable {
public static final long serialVersionUID = 1L;
@Id
@GeneratedValue(generator = "uuid")
@GenericGenerator(name = "uuid", strategy = "uuid2")
@Column(name = "ID", unique = true)
private String ID;
@Column(name = "cd")
private String cd;
@Column(name = "name")
private String name;
@Column(name = "cost")
private String cost;
@Column(name = "dscp")
private String dscp;
@Column(name = "createDate")
private Date createDate;
@Column(name = "updateDate")
private Date updateDate;
@Column(name = "isDel")
private Date isDel; //setter and getter}
=============================================== ===================
@Entity(name = "RoomDetailEntity") @Table(name = "t_room_details") public class RoomDetailEntity implements Serializable {
public static final long serialVersionUID = 1L;
@Id
@GeneratedValue(generator = "uuid")
@GenericGenerator(name = "uuid", strategy = "uuid2")
@Column(name = "ID", unique = true)
private String ID;
@Column(name = "cd")
private String cd;
@Column(name = "name")
private String name;
@Column(name = "dscp")
private String dscp;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "room_category_id", referencedColumnName = "ID")
private RoomCategoryEntity roomCategoryEntity;
@Column(name = "createDate")
private Date createDate;
@Column(name = "updateDate")
private Date updateDate;
@Column(name = "isDel")
private Date isDel;
答案 0 :(得分:0)
我只是尝试将引用表更改为实体,并成功插入
public class RoomDetailDto {
String ID;
@NotEmpty
String cd;
@NotEmpty
String name;
String dscp;
// I change below line
RoomCategoryEntity roomCategoryEntity;
[ { “cd”:“df23”, “名字”:“df23”, “dscp”:“sfdsfs”, “roomCategoryEntity”:{ “cd”:“KLS2”, “名字”:“Kelas 2”, “费用”:“200000”, “dscp”:null, “createDate”:1497535268000, “updateDate”:null, “isDel”:null, “id”:“7f554d7a-3c5d-4c15-921d-fa4b4c629e6c” }, “id”:“02c28356-9783-46a7-8ac5-9e00497d9be2” } ]
