Question

我正在使用JPA和Hibernate来执行简单的查询。它是从两个表，一个应用程序表和一个Transaction表中提取的连接。我可以看到数据返回，但它无法填充我创建的这个POJO，并且无法进行转换。这是查询：

public interface TransactionRepository extends JpaRepository<Transaction, String>{


@Query(value="SELECT "
+ " TXN.TAX_ID taxId, "
+ " APP.AP_DT  apDt, "
+ " TXN.TXN_ID txnId"
+ "      FROM "
+ " APPLICATION APP "
+ "      JOIN "
+ " TRANSACTION TXN "
+ "      ON "
+ " TXN.TXN_ID = APP.TXN_ID "
+ "     WHERE"
+ " APP.CONFIRMATION_ID = ?1", nativeQuery=true)
AnnuityNetPdfToFims getInfoForPdfToFims(String confirmationId);

这是交易实体

@Entity
@Table(name="\"TRANSACTION\"")
@NamedQuery(name="Transaction.findAll", query="SELECT t FROM Transaction t")

public class Transaction implements Serializable {
    private static final long serialVersionUID = 1L;

@Id
@Column(name="TXN_ID")
private String txnId;

@Column(name="ACCT_NUM")
private String acctNum;

@Column(name="ACCT_TYPE_CODE")
private String acctTypeCode;

@Column(name="AGENT_ID")
private String agentId;

@Column(name="AUTO_SUITABILITY_IND")
private String autoSuitabilityInd;

@Column(name="CARRIER_ID")
private String carrierId;

@Column(name="CHANNEL_NAME")
private String channelName;

@Column(name="COMPANY_NAME")
private String companyName;

@Column(name="DELIVERY_STATE")
private String deliveryState;

@Column(name="FIMS_DOCUMENT_ID")
private String fimsDocumentId;

@Column(name="INTERNAL_CONVERSION_IND")
private String internalConversionInd;

@Column(name="JOINT_OWNER_STATE")
private String jointOwnerState;

@Column(name="OWNER_FIRST_NAME")
private String ownerFirstName;

@Column(name="OWNER_LAST_NAME")
private String ownerLastName;

@Column(name="OWNER_TYPE_CODE")
private String ownerTypeCode;

@Column(name="PERSON_IND")
private String personInd;

@Column(name="PRODUCT_CODE")
private String productCode;

@Column(name="PRODUCT_CUSIP")
private String productCusip;

@Column(name="RESIDENCE_STATE")
private String residenceState;

@Column(name="REVIEWER_ID")
private String reviewerId;

@Column(name="SOLICITATION_STATE")
private String solicitationState;

@Column(name="STATUS_CODE")
private String statusCode;

@Column(name="STEP_ACTION_CODE")
private String stepActionCode;

@Column(name="STEP_NAME")
private String stepName;

@Column(name="TAX_ID")
private String taxId;

@Column(name="TR_BY_ID")
private String trById;

@Column(name="TR_TS")
private Timestamp trTs;

@Column(name="TXN_QUALIFIED_IND")
private String txnQualifiedInd;

@Column(name="TXN_XML")
private String txnXml;

@Column(name="UNIT_ID")
private String unitId;

@Column(name="VENDOR_APP_ID")
private String vendorAppId;

@Column(name="G_NUM")
private String gNum;

@Column(name="XTRAC_WORKITEM_ID")
private String xtracWorkitemId;

public Transaction() {
}
//getters and setters

这是应用程序实体

@Entity
@NamedQuery(name="Application.findAll", query="SELECT a FROM Application a")
public class Application implements Serializable {
    private static final long serialVersionUID = 1L;

@EmbeddedId
private ApplicationPK id;

@Temporal(TemporalType.DATE)
@Column(name="AP_DT")
private Date apDt;

@Column(name="DTCC_APPSUB_XML")
private String dtccAppsubXml;

@Column(name="PROCESSING_CODE")
private String processingCode;

@Column(name="TXN_ID")
private String txnId;

public Application() {
} 
//getters and seters

这是我想要填充查询的POJO。

    public class AnnuityNetPdfToFims
{
    private String confirmationId;
    private String taxId;
    private Date   apDt;
    private long   fimsReturnNum;
    private String txnId;
    //getters and setters

所以我可以看到数据又回来了，但它会以Object []的形式返回。我想我可以用它来填充POJO，但我不认为这是非常可靠的。我听说有一种方法可以使用@SqlResultSetMapping注释，但还没有成功使用它。我也听说过我可以在查询中指定对象的实际名称，如下所示：How to map a native query to POJO class using jpa and hibernate。

然而，我也无法让它发挥作用。有什么建议？提前致谢。

使用Spring JPA Query来填充pojo
