部署期間JBoss休眠異常

Question

我有幾個實體的應用程序。在JBoss AS7部署期間，我發生下面列出的異常：

使用想法11.1.3; Ubuntu 12.04; maven 3.0.3，如果需要，我可以顯示項目的pom文件。

這裏是我的類代碼（不含進口）：

@Entity 
@Table(name = "KLADR_SETTINGS",schema ="KLADR") 
public class KladrSettings extends RQObject implements Serializable{ 
    private static final long serialVersionUID = -8557672721736414960L; 
    private String id; 
    private String url; 
    private String pathName; 
    private String namePackage; 
    private int sizeArchive; 
    private Long version; 

    @Id 
    @Column(name = "KLADR_SETTINGS_ID") 
    public String getId() { 
     return id; 
    } 
    public void setId(String id) { 
     this.id = id; 
    } 

    @Column(name = "KLADR_SETTINGS_URL") 
    public String getUrl() { 
     return url; 
    } 
    public void setUrl(String url) { 
     this.url = url; 
    } 

    @Column(name = "KLADR_SETTINGS_PATHNAME") 
    public String getPathName() { 
     return pathName; 
    } 
    public void setPathName(String pathName) { 
     this.pathName = pathName; 
    } 

    @Column(name = "KLADR_SETTINGS_NAMEPACKAGE") 
    public String getNamePackage() { 
     return namePackage; 
    } 
    public void setNamePackage(String namePackage) { 
     this.namePackage = namePackage; 
    } 
    @Column(name = "KLADR_SETTINGS_SIZE_ARCHIVE") 
    public int getSizeArchive() { 
     return sizeArchive; 
    } 
    public void setSizeArchive(int sizeArchive) { 
     this.sizeArchive = sizeArchive; 
    } 

    @Column(name = "KLADR_SETTINGS_VERSION") 
    public Long getVersion() { 
     return version; 
    } 
    public void setVersion(Long version) { 
     this.version = version; 
    } 


    @Override public PortableEntity toPortableEntity(boolean loadCollections, boolean loadNested) { 

     PKladrSettings pentity = new PKladrSettings(getId(), getName(), getVersion(), 
       getDeleted()); 

     pentity.setId(getId()); 
     pentity.setNamePackage(getNamePackage()); 
     pentity.setPathName(getPathName()); 
     pentity.setSizeArchive(getSizeArchive()); 
     pentity.setUrl(getUrl()); 
     pentity.setVersion(getVersion()); 

     return pentity; 

    } 

    @Override public void fromPortable(PortableEntity pentity) { 
     PKladrSettings input = null; 
     if (pentity instanceof PKladrSettings){ 
      input = (PKladrSettings) pentity; 
     } 
     if(input!=null){ 
      this.setId(input.getId()); 
      this.setName(input.getDisplayName()); 
      this.setVersion(input.getVersion()); 
      this.setDeleted(input.isDeleted()); 

      this.setNamePackage(input.getNamePackage()); 
      this.setPathName(input.getPathName()); 
      this.setSizeArchive(input.getSizeArchive()); 
      this.setUrl(input.getUrl()); 

     } 
    } 

    @Override public void loadLazyCollections() { 

    } 
} 

是什麼意思duplicate property mapping？

Answer 1

它看起來像屬性private Long version;定義在超類和擴展類。將其從其中一箇中刪除，它應該可以工作。
