我正在尝试更新一对多关系，但要获得
插入sw_standard_standard（sw_standard_id，standard_id）值 （？，？）[23505-192]];嵌套异常是 org.hibernate.exception.ConstraintViolationException
这是我的代码： SwStandard
@Entity
public class SwStandard implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
private Long id;
@OneToOne
private DeviceType deviceType;
@ElementCollection
@OneToMany
private List<Image> standard;
@ElementCollection
@OneToMany
private List<Image> limited;
@ElementCollection
@OneToMany
private List<Image> exception;
public SwStandard() {}
public SwStandard(DeviceType deviceType, List<Image> standard, List<Image> limited, List<Image> exception) {
this.deviceType = deviceType;
this.standard = standard;
this.limited = limited;
this.exception = exception;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public DeviceType getDeviceType() {
return deviceType;
}
public void setDeviceType(DeviceType deviceType) {
this.deviceType = deviceType;
}
public List<Image> getStandard() {
return standard;
}
public void setStandard(List<Image> standard) {
this.standard = standard;
}
public List<Image> getLimited() {
return limited;
}
public void setLimited(List<Image> limited) {
this.limited = limited;
}
public List<Image> getException() {
return exception;
}
public void setException(List<Image> exception) {
this.exception = exception;
}
}
图像
@Entity
public class Image implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
private Long id;
private String name;
public Image() {}
public Image(String name) {
this.name = name;
}
public Image(Long id, String name) {
this.id = id;
this.name = name;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
更新代码：
@RequestMapping(value = "/swstandard/update", method = RequestMethod.POST)
public SwStandard updateSwStandard(@RequestBody SwStandard request) {
return swService.save(request);
}
SwService：
@Autowired
private SwStandardRepository swService;
SwStandardRepository：
public interface SwStandardRepository extends CrudRepository<SwStandard, Long> {
SwStandard findByDeviceTypeId(Long id);
}
首先我用一个标准项保存SwStandard。然后我保存想用其他东西替换标准项目。当我这样做时，它返回上面的错误。
修改
Alan Hay帮助部分帮助。
现在我无法在SwStandard中保存相同的image，例如这里是一个SwStandard I＆＃39; ll save：
{
"id": 1,
"deviceType": { "id": 1 },
"standard": [{"id": 1}],
"limited": [],
"exception": []
}
这是另一个SwStandard I＆＃39; ll保存，但会因上述错误而失败：
{
"id": 2,
"deviceType": { "id": 2 },
"standard": [{"id": 1}],
"limited": [],
"exception": []
}
正如您所看到的，两个SwStandards都有相同的标准项目。
这是日志输出：
