1.查詢結果爲各個表各個字段（切記要查出primary key,以防後面要更新該數據）
@SuppressWarnings("unchecked")
@Override
public List<TPMSFine> getAlertFailFines(AlertFinishStatus failAlert) {
String selectFields = "tf.id,tf.txnno,tpmsts.certno,tf.finePayDate,tf.operator,"
+ "tf.amount,tf.indictmentNo,tf.indictmentSendDate,tf.penaltyNoticeNo,tf.penaltyNoticeDate,"
+ "tf.penaltyNoticeNoSec,tf.penaltyNoticeDateSec";
String sql = "SELECT " + selectFields + " FROM " + table(TPMSFine.class) + " tf"
+ " inner join tpmstransaction tpmsts on tpmsts.TRANSACTIONDETAILS_TXNNO = tf.txnno"
+ " where tf.ALERTFINISHSTATUS is not null and tf.ALERTFINISHSTATUS = :alertFinishStatus";
Query query = em.createNativeQuery(sql);
query.setParameter("alertFinishStatus", failAlert.ordinal());枚舉類
List<TPMSFine> tpmsFineList = new ArrayList<TPMSFine>();
List<Object[]> resultList = query.getResultList();
for (Object[] objects : resultList) {
TPMSFine tpmsFine = new TPMSFine();
tpmsFine.setId(Long.valueOf(objects[0].toString())); 結果映射，類似JDBC
tpmsFine.setUniqueryCode((String)objects[1]);
tpmsFine.setCertNo(Long.valueOf(objects[2].toString()));
tpmsFine.setFinePayDate((java.util.Date)objects[3]);
tpmsFine.setOperator((String)objects[4]);
tpmsFine.setAmount(Double.valueOf(objects[5].toString()));
tpmsFine.setIndictmentNo((String)objects[6]);
tpmsFine.setIndictmentSendDate((java.util.Date)objects[7]);
tpmsFine.setPenaltyNoticeNo((String)objects[8]);
tpmsFine.setPenaltyNoticeDate((java.util.Date)objects[9]);
tpmsFine.setPenaltyNoticeNoSec((String)objects[10]);
tpmsFine.setPenaltyNoticeDateSec((java.util.Date)objects[11]);
tpmsFineList.add(tpmsFine);
}
return tpmsFineList;
}
2.在類上結合@SqlResultSetMapping()註解映射
@SuppressWarnings("unchecked")
@Override
public List<Transaction> getTransactionsDepositable(SearchTransactionParam param, long first, long count) {
List<Integer> status = new ArrayList<Integer>();
for (WorkflowStatus workflowStatus : param.getWorkflowStatus()) {
status.add(workflowStatus.ordinal());
}
String selectFields = "distinct t.*," + getTxnContentSelectFields();
String sql = "select " + selectFields + " from " + table(Transaction.class) + " t " + "inner join "
+ table(ServiceOperation.class) + " so on so.id = t.serviceoperation_id " + "inner join "
+ table(Service.class) + " s on s.id = so.service_id " + "inner join " + table(Payment.class)
+ " p on p.id = t.payment_id " + "inner join " + table(Zone.class) + " z on z.id = t.zone_id "
+ " left join " + table(TransactionContent.class) + " tc on t.txnno = tc.txnno "
+ " where t.createUid = :createUid and t.workflowStatus in (:workflowStatus) and p.paymentDate = :paymentDate and z.code = :zoneCode ";
if (param.getDepositBatch() != null) {
sql += " and t.depositBatch = :depositBatch ";
}
sql += " ORDER BY t.createTime desc";
Query query = em.createNativeQuery(sql, "FullTransaction");
query.setParameter("createUid", param.getOwnerId());
query.setParameter("paymentDate", param.getPaymentDate() == null ? new Date() : param.getPaymentDate());
query.setParameter("zoneCode", param.getZoneCode());
query.setParameter("workflowStatus", status);
if (param.getDepositBatch() != null) {
query.setParameter("depositBatch", param.getDepositBatch());
}
List<Transaction> transactions = new ArrayList<Transaction>();
List<Object[]> resultList = query.getResultList();
for (Object[] objects : resultList) {
Transaction transaction = (Transaction) objects[0];
transaction.setTransactionContent((TransactionContent) objects[1]);
transactions.add(transaction);
}
return transactions;
// return searchTransactions(param, first, count, "t.createTime desc");
}
------------------------:>java類
查詢的結果不同於列映射名稱的情況下，@FieldResult註解將列的別名映射到實體的字段上
@SuppressWarnings("rawtypes")

@EntityResult(entityClass = TransactionContent.class, fields = {
