Find parent element by searching child / Spring boot JPA + PostgresSQL

I am trying to figure out how to find and return all Books that are associated with a specific author name.
{
"bookId": 5,
"bookName": "test2",
"publishYear": 2022,
"publisher": "test2",
"authors": [
{
"id": 5,
"name": "Heny",
"surname": "Blakc"
},
{
"id": 6,
"name": "Garyy",
"surname": "Harrys"
}
]
}
I want to return all books where Garyy is the author.
I am using Spring Boot + Postgres SQL OneToMany annotation.
Would appreciate any suggestions.

public interface BookRepository extends JpaRepository<BookEntity, Integer> {
public List<BookEntity> findByBookName(String bookName);
public List<BookEntity> findByPublishYear(Integer year);
public List<BookEntity> findByPublisher(String publisher);
}

There are multiple way to do so , one approach is to use forEach and filter in java itself like
List<BookeEntity> books = getBooks();
books.forEach(e->{
List<AuthorEntity> al= e.getAuthors().stream().filter(ee->ee.getName().equals("Garyy")).collect(Collectors.toList());
e.setAuthors(al);
});

Your database design was wrong. Reality:
1 author wrote one or many books,
1 book wrote by one or many authors.
Therefore, you need an table author-book to convert relationship many-many to 2 relationships: one-many, many-one.
You can see https://www.stat.auckland.ac.nz/~paul/ItDT/HTML/node42.html section 5.6.3.2 Relationships

Missing bean in repository

You have in you Report class #Table(name="User"). is this a typo?

any clue ?

could not resolve property Query Exception

I get following exception when I try to display data from EmergencyContact. SurveyData and EmergencyData are related by OneToMany. I'm able to persist the data but not able to retrieve it back.
I want to give a SurveyID as input and get back emergency contacts of that survey. I verified all my setter and getter methods and they look okay. I'm unable to trace where I made mistake. Any help is appreciated.
16:53:42,029 ERROR [stderr] (http-localhost-127.0.0.1-8080-1) Caused by: org.hibernate.QueryException: could not resolve property: survey_id of: masonsurveyejb.businesslogic.EmergencyContact [SELECT emc FROM masonsurveyejb.businesslogic.EmergencyContact emc WHERE emc.survey_id = 11]

Following is the method from which I make query
#Override
public ArrayList<EmergencyContact> GetEmergencyContacts(String survey_id) {
try {
if (survey_id == null || survey_id.length() == 0) {
System.out.println("Received a null or empty survey ID.");
return null;
}
System.out.println("Getting emergency contacts for " + survey_id);
String queryStr = "SELECT emc FROM EmergencyContact emc WHERE emc.survey_id = "
+ survey_id;
Query query = entityManager.createQuery(queryStr);
List resultList = query.getResultList();
if (resultList != null && resultList.size() > 0) {
ArrayList<EmergencyContact> emList = new ArrayList<EmergencyContact>();
for (Object result : resultList) {
EmergencyContact emc = new EmergencyContact();
emc = (EmergencyContact) result;
emList.add(emc);
}
return emList;
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}

You receiving the exception because entity 'EmergencyContact' has no property named 'survey_id'.
Your query should be:
String queryStr = "SELECT emc FROM EmergencyContact emc WHERE emc.surveyData.survey_id = :id";
Query query = entityManager.createQuery(queryStr).setParameter("id", survey_id);
List resultList = query.getResultList();
Please consider 2 things:
Use property names in JPQL query (surveyData.survey_id)
It's better to set query parameters with special method, "setParameter"
