FetchMode只有主鍵列工作

我改變了代碼，但問題仍然存在FetchMode只有主鍵列工作

CandidateResumeInfo candidateResumeInfo = new CandidateResumeInfo(); 
    ArrayList<CandidateResumeInfo> allCandidateResumeInfo= new ArrayList<CandidateResumeInfo>(); 

    Session session = sessionFactory.openSession(); 
    String city1 ="Anniston"; 

    Criteria crit = session.createCriteria(CandidateResumeInfo.class); 
    crit.createAlias("candidate", "candidateinfo"); 

    //crit.setFetchMode("candidateinfo", FetchMode.JOIN); 
    crit.add(Restrictions.eq("candidateinfo.city", city1)); 
    List list = crit.list();

這裏是實體類.. 公共類CandidateResumeInfo實現Serializable { ...

 @OneToMany  
     CandidateInfo candidate; 

     .... 
     } 
     public class CandidateInfo implements Serializable{ 
     ....... 

    @Column(name="city") 
    private String city; 
     ....... 
     }

這裏是堆棧跟蹤的頂部幾行這是一些RPC.class（它在這一行說Throwable cause = e.getCause（）;而在正確的變量端（在調試模式下）有寫java.lang.reflect.InvocationTargetException，但在堆棧跟蹤

public final class RPC { 
    ....... 
    public static String invokeAndEncodeResponse(Object target, 
    Method serviceMethod, Object[] args, 
    SerializationPolicy serializationPolicy, int flags) 
    throws SerializationException { 
if (serviceMethod == null) { 
    throw new NullPointerException("serviceMethod"); 
} 

if (serializationPolicy == null) { 
    throw new NullPointerException("serializationPolicy"); 
} 

String responsePayload; 
try { 
    Object result = serviceMethod.invoke(target, args); 

    responsePayload = encodeResponseForSuccess(serviceMethod, result, 
     serializationPolicy, flags); 
} catch (IllegalAccessException e) { 
    SecurityException securityException = new SecurityException(
     formatIllegalAccessErrorMessage(target, serviceMethod)); 
    securityException.initCause(e); 
    throw securityException; 
} catch (IllegalArgumentException e) { 
    SecurityException securityException = new SecurityException(
     formatIllegalArgumentErrorMessage(target, serviceMethod, args)); 
    securityException.initCause(e); 
    throw securityException; 
} catch (InvocationTargetException e) { 
    // Try to encode the caught exception 
    // 
    **Throwable cause = e.getCause();** // THIS IS THE LINE WHERE IT BRINGS ME .. 

    responsePayload = encodeResponseForFailure(serviceMethod, cause, 
     serializationPolicy, flags); 
}

crit.createAlias("Class2", "c2").add(Restrictions.eq("c2.zip", 123)

應該去做什麼java.lang.reflect.InvocationTargetException ...

如果單純使用 '拉鍊' hibernate將在類Class1中查找屬性zip;它與該物業是PK還是沒有關係。

謝謝，我已經改變了代碼，因爲你說，仍然沒有解決，請審查上面的代碼（我粘貼了實際的代碼），並讓我知道如果我做了一些事情錯了謝謝 – junaidp 2011-05-30 09:01:59

'crit.createAlias 「CandidateInfo」...）;'如果你的財產被稱爲候選人，這應該是'crit.createAlias（「候選人」，...' – 2011-05-30 09:14:59

改變了它，也在上面編輯，問題仍然存在，任何建議。謝謝 – junaidp 2011-05-30 09:49:37
