我正在第一次使用MyEclipse For Spring，它支持hibernate。org.hibernate.TypeMismatchException：提供了錯誤類型的ID
繼MySQL數據庫的相關部分：
CREATE TABLE
`delidete`.`DatiGeneraliVistoContabile` (
`DatiGeneraliId` int NOT NULL, <---- P.K., Foreign key to table Datigenerali
`SoggettiCodice` int NOT NULL, <---- P.K., Foreign key to table Soggetti
`DGVCDataInizio` date NOT NULL,
`DGVCDataFine` date) ;
CREATE TABLE
`delidete`.`DatiGeneraliParereTecnico` (
`DatiGeneraliId` int NOT NULL, <---- P.K., Foreign key to above table (DatigeneraliId)
`TecnicoParereCodice` int NOT NULL, <---- P.K., Foreign key to above table (SoggettiCodice)
`DGTPDescrizione` varchar (255) NOT NULL,
`DGTPDataInizio` date NOT NULL,
`DGTPDataFine` date) ;
ALTER TABLE `delidete`.`DatiGeneraliVistoContabile`
ADD PRIMARY KEY (`DatiGeneraliId`, `SoggettiCodice`) ;
ALTER TABLE `delidete`.`DatiGeneraliParereTecnico`
ADD CONSTRAINT `IDatiGeneraliParereTecnico`
FOREIGN KEY (`DatiGeneraliId`, `TecnicoParereCodice`)
REFERENCES `DatiGeneraliVistoContabile` (`DatiGeneraliId`, `SoggettiCodice`) ;
ALTER TABLE `delidete`.`DatiGeneraliVistoContabile`
ADD CONSTRAINT `IDatiGeneraliVistoContabile2`
FOREIGN KEY (`DatiGeneraliId`)
REFERENCES `DatiGenerali` (`DatiGeneraliId`) ;
ALTER TABLE `delidete`.`DatiGeneraliVistoContabile`
ADD CONSTRAINT `IDatiGeneraliVistoContabile1`
FOREIGN KEY (`SoggettiCodice`)
REFERENCES `Soggetti` (`SoggettiCodice`) ;
這是兩個生成的類：
Datigeneralivistocontabile:
@IdClass(delidete.domain.DatigeneralivistocontabilePK.class)
@Entity
@Table(catalog = "delidete", name = "datigeneralivistocontabile")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(namespace = "DeliDete/delidete/domain", name = "Datigeneralivistocontabile")
public class Datigeneralivistocontabile implements Serializable
{
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumns({@JoinColumn(name = "DatiGeneraliId", referencedColumnName = "DatiGeneraliId", nullable = false, insertable = false, updatable = false)})
@XmlTransient
Datigenerali datigenerali;
@Column(name = "DatiGeneraliId", nullable = false)
@Basic(fetch = FetchType.EAGER)
@Id
@XmlElement

----------------------------------------------------------------------
//don't know why MyEclipse put this link into this class
@OneToOne(mappedBy = "datigeneralivistocontabile", fetch = FetchType.LAZY)
@XmlElement(name = "", namespace = "")
Datigeneralipareretecnico datigeneralipareretecnico;
----------------------------------------------------------------------
@Temporal(TemporalType.DATE)
@Column(name = "DGVCDataFine")
@Basic(fetch = FetchType.EAGER)
@XmlElement
Calendar dgvcdataFine;
@Temporal(TemporalType.DATE)
@Column(name = "DGVCDataInizio", nullable = false)
@Basic(fetch = FetchType.EAGER)
@XmlElement

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumns({@JoinColumn(name = "SoggettiCodice", referencedColumnName = "SoggettiCodice", nullable = false, insertable = false, updatable = false)})
@XmlTransient
Soggetti soggetti;
@Column(name = "SoggettiCodice", nullable = false)
@Basic(fetch = FetchType.EAGER)
@Id
@XmlElement
Integer soggettiCodice;
constructors, getters, setters, toString, other stuff
}
其他類
Datigeneralipareretecnico:
@IdClass(delidete.domain.DatigeneralipareretecnicoPK.class)
@Entity
@Table(catalog = "delidete", name = "datigeneralipareretecnico")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(namespace = "DeliDete/delidete/domain", name = "Datigeneralipareretecnico")
public class Datigeneralipareretecnico implements Serializable
{
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumns({@JoinColumn(name = "IDEnte", referencedColumnName = "DatiGeneraliId", nullable = false)})
@XmlTransient
Datigenerali datigenerali;
@Column(name = "DatiGeneraliId", nullable = false)
@Basic(fetch = FetchType.EAGER)
@Id
@XmlElement
Integer datiGeneraliId;
@PrimaryKeyJoinColumn
@OneToOne(fetch = FetchType.LAZY)
@XmlElement(name = "", namespace = "")
Datigeneralivistocontabile datigeneralivistocontabile;
@Temporal(TemporalType.DATE)
@Column(name = "DGTPDataFine")
@Basic(fetch = FetchType.EAGER)
@XmlElement
Calendar dgtpdataFine;
@Temporal(TemporalType.DATE)
@Column(name = "DGTPDataInizio", nullable = false)
@Basic(fetch = FetchType.EAGER)
@XmlElement
Calendar dgtpdataInizio;
@Column(name = "DGTPDescrizione", nullable = false)
@Basic(fetch = FetchType.EAGER)
@XmlElement
String dgtpdescrizione;
@Column(name = "TecnicoParereCodice", nullable = false)
@Basic(fetch = FetchType.EAGER)
@Id
@XmlElement
Integer tecnicoParereCodice;
constructors, getters, setters, toString, other stuff
}
而且，這兩個PK類：
public class DatigeneralivistocontabilePK implements Serializable
{
@Column(name = "DatiGeneraliId", nullable = false)
@Basic(fetch = FetchType.EAGER)
@Id
public Integer datiGeneraliId;
@Column(name = "SoggettiCodice", nullable = false)
@Basic(fetch = FetchType.EAGER)
@Id
public Integer soggettiCodice;
}
public class DatigeneralipareretecnicoPK implements Serializable
{
@Column(name = "DatiGeneraliId", nullable = false)
@Basic(fetch = FetchType.EAGER)
@Id
public Integer datiGeneraliId;
@Column(name = "TecnicoParereCodice", nullable = false)
@Basic(fetch = FetchType.EAGER)
@Id
public Integer tecnicoParereCodice;
}
現在，當我嘗試保存Datigeneralivistocontabile實體這一切都OK，但是當我嘗試打開一個jsp表明實體獲取：
GRAVE: Servlet.service() for servlet [DeliDete Servlet] in context with path [/DeliDete] threw exception [Request processing failed; nested exception is java.lang.IllegalArgumentException: org.hibernate.TypeMismatchException: Provided id of the wrong type for class delidete.domain.Datigeneralipareretecnico.

我的課都位於包「delidete」 。 拋出此異常的方法是：
@Transactional
public Set<Datigeneralivistocontabile> findAllDatigeneralivistocontabiles(
int startResult, int maxRows) throws DataAccessException
{
Query query = createNamedQuery("findAllDatigeneralivistocontabiles",
startResult, maxRows);
return new LinkedHashSet<Datigeneralivistocontabile>(
query.getResultList()); <---- this line throws the exception
}
和它調用了namedquery是：
@NamedQuery(name = "findAllDatigeneralivistocontabiles", query = "select myDatigeneralivistocontabile from Datigeneralivistocontabile myDatigeneralivistocontabile")
查詢 「從datigeneralivistocontabile選擇*;」在MySQL提示的罰款：
mysql> select * from datigeneralivistocontabile;
+----------------+----------------+----------------+--------------+
| DatiGeneraliId | SoggettiCodice | DGVCDataInizio | DGVCDataFine |
+----------------+----------------+----------------+--------------+
| 1 | 1 | 2011-11-02 | 2011-11-03 |
+----------------+----------------+----------------+--------------+
1 row in set (0.00 sec)
mysql>
我不知道該怎麼辦，因爲我設法幾十喜歡這兩個實體的沒有問題。我注意到的是這是我第一次得到@OneToOne註釋。 也許這是這是造成異常...
在此先感謝大家
編輯：試圖改變列名TecnicoParereCodice到SoggettiCodice也列在第一個表匹配的名字，但沒有發生任何變化：我重新搭建的一切，運行相同的測試，並得到了同樣的錯誤
