JPA / Hibernate：使用輸入和輸出參數調用存儲過程

Question

我在用JPA調用Java中的排序過程時遇到問題

這是Java代碼：

    StoredProcedureQuery storedProcedureQuery = getEntityManager().createNamedStoredProcedureQuery("RECPOCH");

storedProcedureQuery.setParameter(Pochette.SP_RECPOCH_PARAM_STRSTARTSIM, pochetteCriteria.getDebutNumPochette());
storedProcedureQuery.setParameter(Pochette.SP_RECPOCH_PARAM_STRLASTSIM, pochetteCriteria.getFinNumPochette());
storedProcedureQuery.setParameter(Pochette.SP_RECPOCH_PARAM_NACTELID, pochetteCriteria.getActelId());

storedProcedureQuery.execute();
Integer result = (Integer) storedProcedureQuery.getOutputParameterValue(Pochette.SP_RECPOCH_PARAM_NRESULT);

return Long.valueOf(result);

這是代碼Oracle：

"RECPOCH" ( NACTELID IN NUMBER, STRSTARTSIM IN VARCHAR, STRLASTSIM IN VARCHAR, NRESULT OUT INTEGER )

跟蹤異常：

實體中的命名排序過程定義：

    @NamedStoredProcedureQueries({
            @NamedStoredProcedureQuery(name = Pochette.SP_RECPOCH_NAME, procedureName = "RECPOCH", parameters = {
                    @StoredProcedureParameter(name = Pochette.SP_RECPOCH_PARAM_NRESULT, mode = ParameterMode.OUT, type = Long.class),
                    @StoredProcedureParameter(name = Pochette.SP_RECPOCH_PARAM_STRSTARTSIM, mode = ParameterMode.IN, type = String.class),
                    @StoredProcedureParameter(name = Pochette.SP_RECPOCH_PARAM_STRLASTSIM, mode = ParameterMode.IN, type = String.class),
                    @StoredProcedureParameter(name = Pochette.SP_RECPOCH_PARAM_NACTELID, mode = ParameterMode.IN, type = Long.class)
            })
    })

請問您有什么主意嗎？

您還需要注冊存儲過程的參數，因此您的代碼應如下所示：

StoredProcedureQuery storedProcedureQuery = getEntityManager().createNamedStoredProcedureQuery("RECPOCH");

storedProcedureQuery.registerStoredProcedureParameter(Pochette.SP_RECPOCH_PARAM_STRSTARTSIM, String.class, ParameterMode.IN);
storedProcedureQuery.setParameter(Pochette.SP_RECPOCH_PARAM_STRSTARTSIM, pochetteCriteria.getDebutNumPochette());

storedProcedureQuery.registerStoredProcedureParameter(Pochette.SP_RECPOCH_PARAM_STRLASTSIM, String.class, ParameterMode.IN);
storedProcedureQuery.setParameter(Pochette.SP_RECPOCH_PARAM_STRLASTSIM, pochetteCriteria.getFinNumPochette());

storedProcedureQuery.registerStoredProcedureParameter(Pochette.SP_RECPOCH_PARAM_NACTELID, Integer.class, ParameterMode.IN);
storedProcedureQuery.setParameter(Pochette.SP_RECPOCH_PARAM_NACTELID, pochetteCriteria.getActelId());

storedProcedureQuery.registerStoredProcedureParameter(Pochette.SP_RECPOCH_PARAM_NRESULT, Integer.class, ParameterMode.OUT);

storedProcedureQuery.execute();

Integer result = (Integer) storedProcedureQuery.getOutputParameterValue(Pochette.SP_RECPOCH_PARAM_NRESULT);

return Long.valueOf(result);

編輯：這對OP的問題沒有幫助，因為使用了createNamedStoredProcedureQuery ，它會自動聲明並注冊參數。 為了完整起見，我將其保留在此處。
