由于我有三个具有相似结构的数据库表,我创建了一个Embeddable类作为其id重用:
@Embeddable
public class AcceptanceCriteriaId implements Serializable{
private String requestValue;
private String bpvValue;
private Long customerId;
@Column(name="requestValue")
public String getRequestValue() {
return requestValue;
}
public void setRequestValue(String requestValue) {
this.requestValue = requestValue;
}
@Column(name="bpvValue")
public String getBpvValue() {
return bpvValue;
}
public void setBpvValue(String bpvValue) {
this.bpvValue = bpvValue;
}
@Column(name="customerId")
public Long getCustomerId() {
return customerId;
}
public void setCustomerId(Long customerId) {
this.customerId = customerId;
}
}
然后,表的三个实体类将覆盖列的名称:
@Entity
@Table(name = "RSK_XML_TYPE_AC_TBL")
public class TypeAcceptanceCriteria{
private AcceptanceCriteriaId acceptanceCriteriaId;
private ResponseValue response;
@EmbeddedId
@AttributeOverrides(
{
@AttributeOverride(name = "requestValue", column = @Column(name = "REQUEST_TYPE")),
@AttributeOverride(name = "bpvValue", column = @Column(name = "bpv_type")),
@AttributeOverride(name = "customerId", column = @Column(name = "customer_uid"))
}
)
public AcceptanceCriteriaId getAcceptanceCriteriaId() {
return acceptanceCriteriaId;
}
public void setAcceptanceCriteriaId(AcceptanceCriteriaId acceptanceCriteriaId) {
this.acceptanceCriteriaId = acceptanceCriteriaId;
}
@Column(name="response_uid")
@Type(type="com.modules.avm.riskxmlservice.response.utils.ResponseValueEnumType")
public ResponseValue getResponse() {
return response;
}
public void setResponse(ResponseValue response) {
this.response = response;
}
}
所以,如果这里没有错误,我期待这两种方法中的一种工作:
@Repository
public class HibernateTypeAcceptanceCriteriaDAO extends AbstractAvmAppHibernateDAO<TypeAcceptanceCriteria> implements TypeAcceptanceCriteriaDAO {
protected HibernateTypeAcceptanceCriteriaDAO() {
super(TypeAcceptanceCriteria.class);
}
public TypeAcceptanceCriteria getTypeAcceptanceCriteria_v1(String requestValue, String bpvValue, Long customerId) {
return (TypeAcceptanceCriteria) createCriteria()
.add(Restrictions.eq("acceptanceCriteriaId.requestValue", requestValue))
.add(Restrictions.eq("acceptanceCriteriaId.bpvValue", bpvValue))
.add(Restrictions.in("acceptanceCriteriaId.customerId", new Long[]{0L, customerId}))
.add(Restrictions.sqlRestriction(" ROWNUM = 1 "))
.addOrder(Order.desc("acceptanceCriteriaId.customerId"))
.uniqueResult();
}
@Override
public TypeAcceptanceCriteria getTypeAcceptanceCriteria(String requestValue, String bpvValue, Long customerId) {
return (TypeAcceptanceCriteria) getSession().createSQLQuery("select * from RSK_XML_type_AC_TBL where request_type = :requestValue and bpv_type= :bpvValue and customer_uid in (0, :customerId) and rownum = 1 order by customer_uid desc")
.setResultTransformer(new AliasToBeanResultTransformer(TypeAcceptanceCriteria.class))
.setString("requestValue", requestValue)
.setString("bpvValue", bpvValue)
.setLong("customerId", customerId).uniqueResult();
}
}
但是我收到以下错误:java.lang.RuntimeException:java.lang.NoSuchFieldException:REQUEST_TYPE
如果有人能解释我的错误,我真的很感激... 谢谢!
