问题描述
我有两个实体类StreetAddress，另一个是sourceStreetAddress，它们通过OnetoOne映射关联，如下所示。
街道地址
@Entity
@Table(name = "T_STREET_ADDRESS")
@discriminatorValue(value = "STRT")
@PrimaryKeyJoinColumn(name = "STREET_ADDRESS_ID")
public class StreetAddress extends Address implements AuditableLevelTwo,Serializable {
private static final long serialVersionUID = 409694762467210951L;
@Column(name = "ADDRESS_LINE_1_TXT",length = 240)
private String addressLine1Text;
@Column(name = "ADDRESS_LINE_2_TXT",length = 240)
private String addressLine2Text;
@Transient
private String addressLine3Text;
@Column(name = "CARRIER_ROUTE_TXT")
private String carrierRouteText;
@Column(name = "CITY_NM",length = 100)
private String cityName;
@Column(name = "CLEAN_ADDRESS_IND",nullable = true,length = 1)
private String cleanAddressIndicator;
@Column(name = "COUNTRY_CD",length = 3)
private String countryCode;
@Column(name = "DATA_SOURCE_TYPE_CD")
private String dataSourceType;
@Column(name = "FULL_POSTAL_CODE_TXT",length = 20,unique = false)
private String fullPostalCodeText;
@Embedded
private Audit levelTwoAudit;
@OnetoOne(fetch = FetchType.EAGER,mappedBy = "streetAddress",cascade = CascadeType.ALL)
private ServiceAddress serviceAddress;
@Column(name = "SERVICE_ADDRESS_FLAG",length = 1)
private String serviceAddressFlag;
@OnetoOne(fetch = FetchType.EAGER,cascade = CascadeType.ALL)
private SourceStreetAddress sourceStreetAddress;
@OnetoMany(fetch = FetchType.EAGER,cascade = CascadeType.ALL,mappedBy = "streetAddress")
@Fetch(FetchMode.SELECT)
private Set<StreetAddressServicability> streetAddressServicability = new HashSet<StreetAddressServicability>();
@Column(name = "TERRITORY_CD",length = 2)
private String territoryCode;
@Column(name = "VALID_ADDRESS_IND",length = 1)
private String validAddressIndicator;
@Column(name = "ZIP4",insertable = false,updatable = false)
private String ZIP4;
@Column(name = "ZIP5",updatable = false)
private String ZIP5;
public StreetAddress() {
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (getClass() != obj.getClass())
return false;
StreetAddress other = (StreetAddress) obj;
if (addressLine1Text == null) {
if (other.addressLine1Text != null)
return false;
} else if (!addressLine1Text.equals(other.addressLine1Text))
return false;
if (addressLine2Text == null) {
if (other.addressLine2Text != null)
return false;
} else if (!addressLine2Text.equals(other.addressLine2Text))
return false;
if (cityName == null) {
if (other.cityName != null)
return false;
} else if (!cityName.equals(other.cityName))
return false;
if (fullPostalCodeText == null || fullPostalCodeText.trim().equals("") || fullPostalCodeText.trim().length() < 5) {
if (other.fullPostalCodeText != null)
return false;
} else if (!fullPostalCodeText.replace("-","").substring(0,5)
.equals(other.fullPostalCodeText != null && other.fullPostalCodeText.replace("-","").length() >= 5 ? other.fullPostalCodeText.replace("-",5) : ""))
return false;
if (territoryCode == null) {
if (other.territoryCode != null)
return false;
} else if (!territoryCode.equals(other.territoryCode))
return false;
return true;
}
// getter and setter
}
SourceStreetAddress
@Entity
@Table(name = "T_SOURCE_STREET_ADDRESS")
public class SourceStreetAddress extends AbstractSequencedModelObject<Long> {
private static final long serialVersionUID = 409694762467210951L;
@Column(name = "ADDRESS_LINE_1_TXT",length = 240)
private String addressLine2Text;
@Embedded
private Audit audit;
@Column(name = "CITY_NM",length = 100)
private String cityName;
@Column(name = "COUNTRY_CD",length = 100)
private String countryCode;
@Column(name = "POSTAL_CODE_TXT",length = 100)
private String fullPostalCodeText;
@Id
@Column(name = "SOURCE_STREET_ADDRESS_ID",length = 19,nullable = false)
private Long id;
@MapsId
@OnetoOne(fetch = FetchType.EAGER,optional = true)
@JoinColumn(name = "SOURCE_STREET_ADDRESS_ID",referencedColumnName = "STREET_ADDRESS_ID",nullable = false,unique = false,insertable = true,updatable = true)
private StreetAddress streetAddress;
@Column(name = "TERRITORY_CD",length = 100)
private String territoryCode;
// getter and setter
}
所以当我第一次测试它时，我在下面遇到了异常
A different object with the same identifier value was already associated with the session : [com.charter.enterprise.domain.sourceStreetAddress#80023962]A different object with the same identifier value was already associated with the session : [com.charter.enterprise.domain.sourceStreetAddress#80023962]
但是我读过某处，这个异常表明Hibernate试图插入一个已经存在的实体（SourceStreetAddress实体）。可能是因为
Cascade.ALL代表StreetAddress内的SourceStreetAddress属性。
因此我将其更改为CascadeType.MERGE，希望它会首先检查SourceStreetAddress实体是否存在，然后尝试插入，否则它将只进行更新。
@OnetoOne(fetch = FetchType.EAGER,cascade = CascadeType.MERGE)
private SourceStreetAddress sourceStreetAddress;
但是现在我在下面遇到了异常：
org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.TransientPropertyValueException: object references an unsaved transient instance - save the transient instance before flushing : com.charter.enterprise.domain.StreetAddress.sourceStreetAddress -> com.charter.enterprise.domain.sourceStreetAddress;
我已经面对这个问题已经有一段时间了。 请任何人帮助我如何解决它以及这里出了什么问题。
要保存对象并引发异常的代码部分

}
if (!CollectionUtils.isEmpty(reqAddressMemos)) {
