Call oracle function with MyBatis (Annotation Based)

Question

I need call Oracle Function in MyBatis using Annotations.

My Mapper:

@Select("{ CALL #{outParam, jdbcType=NUMERIC, mode=OUT} := ORA_FUNC( "
    + "#{pNum1, jdbcType=NUMERIC, mode=IN},"
    + "#{pNum2, jdbcType=NUMERIC, mode=IN},"
    + "#{pNum3, jdbcType=NUMERIC, mode=IN} )}")
@Options(statementType = StatementType.CALLABLE)
@ResultType(Integer.class)
public Integer executeFunction(
    @Param("map") Map<String, Object> carteira);

and my call to this signature:

Map<String, Object> mapParameters = new HashMap<String, Object>();
mapParameters.put("pNum1", carteira.getUnimedCarteira());
mapParameters.put("pNum2", carteira.getCodCarteira());
mapParameters.put("pNum3", carteira.getDigitoCarteira());
mapper.obterRedeBeneficiario(mapParameters);
return mapParameters.get("outParam").toString();

The outParam is null and the return of mapper is null too.

Can anyone help-me?

Answer 1

create a domain class SpInOut class

class SpInOut{

    private String outParam;
    private int pNum1;
    private int pNum2;
    private int pNum3;

    //Getters and setters

}

And you can change your maaper as below

@Select("{ #{outParam, jdbcType=NUMERIC, mode=OUT} = CALL ORA_FUNC( "
    + "#{pNum1, jdbcType=NUMERIC, mode=IN},"
    + "#{pNum2, jdbcType=NUMERIC, mode=IN},"
    + "#{pNum3, jdbcType=NUMERIC, mode=IN} )}")
@Options(statementType = StatementType.CALLABLE)
public void executeFunction(
    SpInOut inOut);
