How to catch the SqlExceptionHelper in spring boot? - spring-boot

Question

I could not capture that error that comes from the stored procedure that I created.
create procedure sp_users
#option int = 0,
#nom_user varchar(50) = null,
#ema_user varchar(50) = null
as
begin
set nocount on
begin try
if #option = 2
begin
if not exists (select * from tb_users where ema_user = #ema_user)
begin
insert into tb_users values (#nom_user,#ema_user)
end
else
begin
raiserror('The email already exists',16,1)
end
end
end try
begin catch
declare #errorMessage varchar(100), #errorSeverity int, #errorState int
set #errorMessage = error_message()
set #errorSeverity = error_severity()
set #errorState = error_state()
raiserror(#errorMessage,#errorSeverity,#errorState)
end catch
end
when I enter an email that already exists, it shows me the message.
Msg 50000, Level 16, State 1, Procedure sp_users, Line 71 [Batch Start Line 81]
The email already exists
this is the code that I made in spring boot
#Service
public class CrudUserService implements CrudUserDAO{
#PersistenceContext
private EntityManager em;
#SuppressWarnings({ "unchecked" })
#Override
public ValidateApiResponse MntUser(Integer op, String nom, String ema) {
ValidateApiResponse vapi = new ValidateApiResponse();
Session session = em.unwrap(Session.class);
try {
ProcedureCall call = session.createStoredProcedureCall("sp_users");
call.registerParameter(1, Integer.class, ParameterMode.IN);
call.registerParameter(2, String.class, ParameterMode.IN).enablePassingNulls(true);
call.registerParameter(3, String.class, ParameterMode.IN).enablePassingNulls(true);
call.setParameter(1, op);
call.setParameter(2, nom);
call.setParameter(3, ema);
call.execute();
vapi.dTable = call.getResultList();
vapi.Attr = "OK";
} catch (Exception e) {
//vapi.Attr = "";
//vapi.Error = e.getMessage();
System.out.println(e.getMessage());
} finally {
session.close();
}
return vapi;
}
}
when I try to capture the error in spring boot I get this in the console. it shows me the message, but I can't capture that message from SqlExceptionHelper.

I have already solved it, but creating an output parameter.
procedure
create proc sp_users
#option int = 0,
#nom_user varchar(50) = null,
#ema_user varchar(50) = null,
#message_error varchar(50) = null output
as
begin
set nocount on
begin try
if #option = 2
begin
if not exists(select * from tb_users where ema_user = #ema_user)
begin
insert into tb_users values(#nom_user,#ema_user)
end
else
begin
set #message_error = 'The email already exists'
raiserror(#message,16,1)
end
end
end try
begin catch
print error_message()
end catch
end
spring boot
#Service
public class CrudUserService implements CrudUserDAO {
#PersistenceContext
private EntityManager em;
#SuppressWarnings({ "unchecked" })
#Override
public ValidateApiResponse MntUser(Integer op, String nom, String ema) {
ValidateApiResponse vapi = new ValidateApiResponse();
Session session = em.unwrap(Session.class);
ProcedureCall call = session.createStoredProcedureCall("sp_users");
call.registerParameter(1, Integer.class, ParameterMode.IN);
call.registerParameter(2, String.class, ParameterMode.IN).enablePassingNulls(true);
call.registerParameter(3, String.class, ParameterMode.IN).enablePassingNulls(true);
call.registerParameter(4, String.class, ParameterMode.OUT).enablePassingNulls(true);
call.setParameter(1, op);
call.setParameter(2, nom);
call.setParameter(3, ema);
call.execute();
String message = (String) call.getOutputParameterValue(4);
if (message == "" || message == null) {
vapi.dTable = call.getResultList();
vapi.Attr = "OK";
} else {
vapi.Attr = "";
vapi.Error = message;
}
return vapi;
}
}
This is the message I get when I enter an email that already exists.
"Msj": "Internal Server Error",
"MsjDetail": "The email already exists",
"dtCollection": [],
