休眠查詢例外：無法在擁有實體上創建批評

Question

我無法訪問嵌入類中的值。

Criteria cr = this.getHibernateTemplate().getSessionFactory().openSession().createCriteria(DuaVO.class,"Dua"); 

if (duaSearchVO.getContractNum()!=null && !duaSearchVO.getContractNum().isEmpty()) { 
    cr.createCriteria("Dua.contractFundingDetails", "contractFundingDetails"); 
    cr.add(Restrictions.eq("contractFundingDetails.contractNumber", duaSearchVO.getContractNum())); 
    flag = true; 
} 

JUnit測試

@Test 
public void testsearchDua() { 
    DuaSearchVO duaSearchVO = new DuaSearchVO(); 

    //ContractFundingDetailsVO - contractNumber 
    duaSearchVO.setContractNum("HHS12132423"); 


    List<Object[]> result = duaSearchDaoImpl.searchDua(duaSearchVO); 


    Assert.assertNotNull(result); 
} 

我得到這個例外。

org.hibernate.QueryException: Criteria objects cannot be created directly on components. Create a criteria on owning entity and use a dotted property to access component property: contractFundingDetails

主類（DuaVO）

@Embedded 
private ContractFundingDetailsVO contractFundingDetails; 

嵌入類

@Embeddable 
    public class ContractFundingDetailsVO implements Serializable 
    { 
     @Column(name="CNTRCT_NUM") 
     private String contractNumber; 
     }

解決。

因爲沒有連接，所以我不必創建createCriteria（）方法。

cr.add(Restrictions.eq 
("Dua.contractFundingDetails.contractNumber", duaSearchVO.getContractNum())); 

       flag = true; 
      }
