JPA stackoverflow error when fetching data

I have 2 entities namely Teacher and Club, I need to retrieve the teacher data along with its related club and/or sports.
I a bit new to JPA so am having trouble debugging the stack overflow error I get when I use the findAll method on the Teacher repository.
I had tried adding #JsonIgnore annotation to my one-to-many annotation to deal with the recursion problem as suggested in some similar questions but was still getting problems and am not sure how exactly it's supposed to solve the problem.

this.id = id;

Hibernate search is not working

I am developping a java/jee application in which i am using spring boot and hibernate as frameworks i used hibernate search for full text searching but unfortunately i always got an empty list as result.I am using hibernate version 5.1 and hibernate search orm version 5.5.3.Final.Here is my code :
public void search() {
FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(this.em);
try {
fullTextEntityManager.createIndexer().startAndWait();
// create native Lucene query unsing the query DSL
// alternatively you can write the Lucene query using the Lucene
// query parser
// or the Lucene programmatic API. The Hibernate Search DSL is
// recommended though
QueryBuilder queryBuilder = fullTextEntityManager.getSearchFactory()
.buildQueryBuilder()
.forEntity(Application.class)
.get();
org.apache.lucene.search.Query luceneQuery = queryBuilder.keyword().wildcard().onField("reference").matching("di*")
.createQuery();
// wrap Lucene query in a javax.persistence.Query
javax.persistence.Query jpaQuery = fullTextEntityManager.createFullTextQuery(luceneQuery,
Application.class);
// execute search
List<Application> result = jpaQuery.getResultList();
System.out.println("your result list is "+result);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

I have solved my problem.It was because of subclasses which were not indexed.

Did you make sure your entities are indexed before searching?
If you are using a pre-existing database, or if you initialized your database without using Hibernate ORM APIs (by using SQL directly, or by restoring a dump), your entities are probably not indexed yet.
You should have a look at the mass indexer, which makes it easy to index a lot of entities: https://docs.jboss.org/hibernate/search/5.5/reference/en-US/html_single/#search-batchindex-massindexer

Spring Boot JpaRepository save call doesn't seem to be doing anything

I'm writing a Spring Boot application that uses JpaRepository interfaces. In a service method where I'm attempting to write some objects, calls to two repositories' save() methods don't appear to be doing anything, but are also not throwing any exceptions.
I'm using mysql, with ISAM tables, with MySQL5Dialect.

According to what I've read on the subject, methods annotated with #Transactional should commit once the method returns. When I execute the method, it does in fact print to the log that it's saving. However, I have sql debugging turned on, and it does not print any sql statements when it saves. (it does print sql statements on selects.)
The method has no problems doing the selects above, only the saves in the latter part. No exceptions are thrown, but the data doesn't appear in the tables that the entities are using. The only line that gets printed in the log for each save looks like this:
o.s.t.i.TransactionInterceptor : Completing transaction for [org.springframework.data.jpa.repository.support.SimpleJpaRepository.save]
I'm not sure if this is relevant, but this call is made by the listener class for a jms queue.
My question is, am I missing anything to enable persisting data in this way? From what I've read, #Transactional automatically has readOnly set to true, and my IDE confirms this. Did I miss something important?

For anyone reading this in the future, the root cause of the issue was that the service method call was coming from a message queue receiver class. I'm not sure why. When I moved the call directly to the web service instead of the queue receiver, the insert happened with no issues.

Mapping issue on Hibernate

I am in the middle of developing a JHipster project and I've come to a halt due to what I believe to be mapping issues
My Database has several tables, but the two that affect me here are Study and Publication, where they have a Many to Many relationship.
I need to retrieve the collection of Publications where a study can be published, hence Study is the owner of the relationship, but for some reason, Hibernate don't recognise the attributes I map the relation with.
All of this started trying to solve a lazy connection issue, yes I have been through most posts relating this and I have tried everything that made sense to me.
Here the code of Study:
#Audited
#Entity
#Table(name = "Study")
#Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
#Document(indexName = "study")
public class Study implements Serializable {

So, if anyone could throw some light on to this, it would be very helpful!
I Edit to add the main exception it throws:
Caused by: org.hibernate.QueryException: could not resolve property: publications of: org.wwarn.vivax.manager.domain.Study

You have a typo in your entity definition: "publicationss" instead of "publications". Since Hibernate uses JavaBeans properties for data access, it complains about getPublications() loss in your definition.
Metamodel preserves you from such typos, consider using it.

issue with a Criteria when querying a many to many association

I have an issue with how hibernate implemented a many to many relationship.
Hibernate created the 2 following classes to map the tables relationship:

I apologize for the fields naes in French.
Now, when I try to catch all of the entities:
List l = session.createCriteria(CategoriesDuSpectacle.class).list();
This works fine.
But when I try to add a criteria:
l = session.createCriteria(CategoriesDuSpectacle.class).add(Restrictions.ilike("commentaire", "a")).list();
I get the following error:
org.hibernate.QueryException: could not resolve property: commentaire of: entities.CategoriesDuSpectacle
This sounds strange to me as the concerned field is mentionned in CategoriesDuSpectacle class:
#EmbeddedId
#AttributeOverrides({
{...}
#AttributeOverride(name = "commentaire", column = #Column(name = "Commentaire")),
{...}
})
Any idea about what I missed?
Thx in advance.

a good night made me figure it out.
I used the parameter on the wrong object:
l = session.createCriteria(CategoriesDuSpectacle.class).add(Restrictions.ilike("commentaire", "a")).list();
While it should have been this way:
l = session.createCriteria(CategoriesDuSpectacle.class).add(Restrictions.ilike("id.commentaire", "a")).list();
Hope it will help someone else.
