Query method to find from a list - spring-boot

Question

I want to get the object from communication table that has Integer x in appointment_type_ids. Can I write a finder method for that?
Communication.java
#Getter
#Setter
#Entity
#Table(name = "communication")
public class Communication{
#Column("id")
private Long id;
#Column("name")
private String name;
#Column("appointment_type_ids")
private ArrayList<Integer> appointmentTypeIds;
}
I tried putting List<Communication> findByAppointmentTypeIdsContaining(Integer integer); in the repository, as suggested by #João Dias.
Following is the error log I get
Caused by: org.springframework.data.repository.query.QueryCreationException: Could not create query for public abstract java.util.List com.CommunicationRepository.findByAppointmentTypeIdsContaining(java.lang.Integer)! Reason: Failed to create query for method public abstract java.util.List com.CommunicationRepository.findByAppointmentTypeIdsContaining(java.lang.Integer)! unknown collection expression type [org.hibernate.query.criteria.internal.path.SingularAttributePath]; nested exception is java.lang.IllegalArgumentException: Failed to create query for method public abstract java.util.List com.CommunicationRepository.findByAppointmentTypeIdsContaining(java.lang.Integer)! unknown collection expression type [org.hibernate.query.criteria.internal.path.SingularAttributePath]

Answer 1

In your repository for Communication try adding the following method:
List<Communication> findByAppointmentTypeIdsContaining(Integer appointmentTypeId);
