Вызов процедуры SQL-сервера с ошибкой Spring boot jpa: «Невозможно извлечь значение параметра OUT / INOUT»

Question

Мы пытаемся вызвать вызов процедуры SQL-сервера (3 параметра):

ALTER PROCEDURE [mvm].[CHECK_USER]
   @IN_USER char(40),
   @IN_PASS char(40),
   @OUT_OK  int output
AS
BEGIN TRY ...
...
SET @OUT_OK = 0
...
RETURN @OUT_OK (Yes! It has a return)

В приложении Java Spring Boot мы добавляем их в pom.xml

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

Имы сделали два подхода в репозитории:

Aproach 1 (Аннотации):

@Entity
@NamedStoredProcedureQueries({
    @NamedStoredProcedureQuery(
        name = "CheckUser",
        procedureName = "mvm.CHECK_USER",
        parameters = {
          @StoredProcedureParameter(mode = ParameterMode.IN, /*name = "@IN_USER",*/ type = String.class),
          @StoredProcedureParameter(mode = ParameterMode.IN, /*name = "@IN_PASS",*/ type = String.class),
          @StoredProcedureParameter(mode = ParameterMode.INOUT /*name = "@OUT_OK",*/, type = Long.class  )
        })
})
public class User implements Serializable {

    @Id //To avoid build fail
    private int id; 
}

А затем:

public interface TableCheckUser extends CrudRepository<User, Long> {

    @Procedure(name = "CheckUser")
    Long checkUser(String user, String password, Long value);

}

В этом случае мы имеем ошибку:

org.springframework.dao.InvalidDataAccessApiUsageException: Could not locate parameter registered using that position [4]; nested exception is java.lang.IllegalArgumentException: Could not locate parameter registered using that position [4]

Aproach 2 (Writed):

@Repository
public class ProcedureInvoker {

    private final EntityManager entityManager;

    @Autowired
    public ProcedureInvoker(final EntityManager entityManager) {
        this.entityManager = entityManager;
    }
public long getCheckUserValue(String user, String password) {

        StoredProcedureQuery storedProcedureQuery = entityManager.createStoredProcedureQuery("mvm.CHECK_USER");


        storedProcedureQuery.registerStoredProcedureParameter(1, String.class, ParameterMode.IN);
        storedProcedureQuery.registerStoredProcedureParameter(2, String.class, ParameterMode.IN);
        storedProcedureQuery.registerStoredProcedureParameter(3, Long.class, ParameterMode.INOUT);


        storedProcedureQuery.setParameter(1, user);
        storedProcedureQuery.setParameter(2, password);
        storedProcedureQuery.setParameter(3, new Long(3));

        storedProcedureQuery.execute();

//Another try (with fail) Call to stored procedure [mvm.checkUser] returned no results
        //Object myobj = storedProcedureQuery.getSingleResult();
        //final Long otherlong = (Long) myobj;

        final Long outputValue2 = (Long) storedProcedureQuery.getOutputParameterValue(3);

        return outputValue2; 
    }

И мы получаем:

2018-09-28 09:36:15.697 TRACE -- [nio-8080-exec-4] o.h.t.d.s.BasicBinder                    : binding parameter [1] as [VARCHAR] - [myuser]

Мы попробовали несколько подходов (добавить параметр, удалить выходной параметр), но сошибка.

Спасибо!

Answer 1

Решено !!

Мне не нужна строка execute ().Работает только с этим:

   StoredProcedureQuery storedProcedureQuery = entityManager.createStoredProcedureQuery("mvm.CHECK_USER");


        storedProcedureQuery.registerStoredProcedureParameter(1, String.class, ParameterMode.IN);
        storedProcedureQuery.registerStoredProcedureParameter(2, String.class, ParameterMode.IN);
        storedProcedureQuery.registerStoredProcedureParameter(3, Long.class, ParameterMode.INOUT);


        storedProcedureQuery.setParameter(1, user);
        storedProcedureQuery.setParameter(2, password);
        storedProcedureQuery.setParameter(3, new Long(3));

        Long outputValue2 = (Long) storedProcedureQuery.getOutputParameterValue(3);
