Need to call StoredProcedure in jave using Hibernate - java

Just want to call Stored procedure of SQL server from java using Hibernate as ORM.
The stored Procedure has so many result set which I am keeping it in Java as DTO's and each one as list in one DTO to send as JSON payload for Front-end integration.
But I am getting exception saying"org.hibernate.MappingException: Unknown entity: com.test.plans.dto.TemplatesDTO"
public ItemDetailsDTO getItemDetails(int no) {
Session session = getSession();
Connection connection = null;
List<ItemDetailsDTO> resultList = new ArrayList<>();
try {
ResultSet rs = null;
SessionImpl sessionImpl = (SessionImpl) session;
connection = sessionImpl.connection();
Query query = session.createSQLQuery("exec usp_GetItemDetails :no")
.addEntity(TemplatesDTO.class)
.setParameter("no", no);
resultList = query.list();
} catch (Exception e) {
System.out.println("error");
e.printStackTrace();
}
return resultList.get(0);
}
DTO :
import java.util.List;
public class ItemDetailsDTO {
private List<TemplatesDTO> templates;
public List<TemplatesDTO> gettemplates() {
return templates;
}
public void settemplates(List<TemplatesDTO> templates) {
this.templates = templates;
}
}
Please find below complete trace of exception

}
private static final org.slf4j.Logger LOG = LoggerFactory.getLogger(ReportingPluginJob.class);
#Override

} catch (ApplicationException e) {
LOG.error("FAILED TO CREATE A REPORT FOR SPACE " + key + " with error: " + System.lineSeparator()

According the stack trace, I've got a problem during the page save (saveContentEntity). It seems, the page save needs to update a space associated with the page too.
And here comes the problem. According to the stack trace, this space exists in the Hibernate session already. evict and clear of the actual session does not work.
Any suggestions, how can I handle this exception, or how can I actually remove the space from Hibernate session?
Apparently, this is what's happening in your code:
Within your SpaceManager, your session finds a Session object with ID 1 (assume that) and returns it.
Your method uses this reference to associate with another object, a Page one.
And finally, your PageManager persist this data in the database.
Probably, your problem is problem that:
From step 1 to 2, when the SpaceManager returns the data, your transaction is ended and your returned object becomes detached.
After that, when you call save, you are trying to persist a detached Session, but it already exists in the database. Then you get an exception.
You could try to use the merge method or remove the cascade from this reference in your entity.
(Please provide your entity code so I can improve my answer if there's anything wrong or which don't work for you.)
We ran into the same problem and what solved it for us was to put the code that creates the page (and loads other objects, like the space or the parent page) all into a transaction:
private void createNewPage(String title, String pageInput, Long parentPageId, String spaceKey) {
transactionTemplate.execute(() -> {
Page page = new Page();
page.setTitle(title);
page.setBodyAsString(pageInput);
Space space = spaceManager.getSpace(spaceKey);
page.setSpace(space);
Page parentPage = pageManager.getPage(parentPageId);
if (parentPage != null) {
page.setParentPage(parentPage);
parentPage.addChild(page);
}
pageManager.saveContentEntity(page, DefaultSaveContext.DEFAULT);
return null;
});
}
com.atlassian.sal.api.transaction.TransactionTemplate can be injected with #ComponentImport

While using SpringBoot with MSSQL server stored proc, when the value is null, Stored proc fails to execute. the value have default as null while calling.
If the parameters are excluded, the proc works. But as these are optional parameters, what are my options to call the stored proc?
When i try to pass null while calling the stored procedure, it is failing with this error.

And this is the method identificaPantalla in the class GestionPantallas, where the conexion method is.
public static int identificaPantalla(ScreenDesc[] pantallas) throws TnDriverException {
int result = -1;
try {
result = session.waitFor(pantallas);
}
catch(TnDriverException e) {
throw e;
}
return result;
}
Any idea about this issue?
