JPA could not locate parameter while working with Stored procedure using Postgres - postgresql

Question

Any efforts in following problem would be highly appreciable.
I am trying to invoke stored procedure using #NamedStoredProcedureQueries
Here is the code snippet of my entity class
#Entity
#Table(name = "tx_oppertunity")
#NamedStoredProcedureQueries({ //
#NamedStoredProcedureQuery(name = "oppertunity.pastOppertunities", procedureName = "pastOppertunities",resultSetMappings="myMapping")})
#SqlResultSetMappings({
#SqlResultSetMapping(
name = "myMapping",
classes = #ConstructorResult(targetClass = DataHolder.class, columns = { #ColumnResult(name = "oppertunityid") }))
})
public class Oppertunity {
/** The oppertunity id. */
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "GEN_TX_OPPERTUNITY_SEQ")
#SequenceGenerator(allocationSize = 1, name = "GEN_TX_OPPERTUNITY_SEQ", sequenceName = "tx_oppertunity_seq")
#Column(name = "oppertunity_id", nullable = false, unique = true)
private Long oppertunity_id;
// other fields to follow
}
My stored procedure is written in postgres and looks like this.
CREATE OR REPLACE FUNCTION pastOppertunities()
RETURNS TABLE(oppertunityid integer) AS
$BODY$
BEGIN
RETURN QUERY select cast((opp.oppertunity_id) as integer) from tx_oppertunity opp where (opp.end_date)< (NOW() - INTERVAL '2 days');
END;
$BODY$
LANGUAGE plpgsql
Since I am using SQL Resultset mapping to map my result from stored procedure I have defined target class to hold those values as DataHolder.class which looks like this.
public class DataHolder implements Serializable{
private Integer oppertunityid;
/**
* #return the oppertunityid
*/
public Integer getOppertunityid() {
return oppertunityid;
}
/**
* #param oppertunityid the oppertunityid to set
*/
public void setOppertunityid(Integer oppertunityid) {
this.oppertunityid = oppertunityid;
}
public DataHolder(Integer oppertunityid) {
this.oppertunityid = oppertunityid;
}
}
However If I try to run the procedure using, JPA repository
#Procedure(name = "oppertunity.pastOppertunities")
public List<DataHolder> findPastOppertunities();
It gives me following exception,
11:51:07.200 [http-nio-8000-exec-7] ERROR o.a.c.c.C.[.[.[.[dispatcherServlet] - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Could not locate parameter registered using that position [1]; nested exception is java.lang.IllegalArgumentException: Could not locate parameter registered using that position [1]] with root cause

I am not sure what exactly I am missing here all parameters are specified correctly in #SQLREsultSetMapping and I added explicit typecast in procedure to compulsory return Integer value.
There was some post which was suggesting to use Entity manager to call stored procedure, after a long fight I made call using entity manager and it worked like a charm
public List<DataHolder> findPastOppertunities() {
// TODO Auto-generated method stub
StoredProcedureQuery spq = em.createStoredProcedureQuery("pastOppertunities");
List<DataHolder> resultList = spq.getResultList();
return resultList;
//return oppRepo.findPastOppertunities();
}
However I want to understand if its bug with JPA repositories, Why JPA is not able to map result from strored procedure using #SqlResultSetMapping.
Thanks,
Dipesh
