Exception Thrown by CrudRepository save method - exception

Question

I am using CrudRepository save method to persist Profile Object in my Spring boot project as below:
MyService2.java:
public Profile getProfile(String profileId, String email){
Profile profile = null;
MyClass myObj=new MyClass();
Profile profile = new Profile(profileId, email);
return myRepository.save(profile);;
}
MyService1.java:
public Profile getProfile(String profileId, String email){
try{
return myService2.getProfile(profileId,email);
}
catch(Exception e){
{
throw new MyCustomException(errorMessage, errorCode);
}
}
MyRepository.java
public interface MyRepository extends PagingAndSortingRepository<Profile, String> {
........
}
Profile.java:
#Entity
public class Profile extends BaseDomain {
#Id
private String id;
private String username;
public Profile() {
//this is no argument constructor
}
public Profile(final String id,final String email) {
this.id = id;
this.username= email;
}
//Getter and Setter
}
In Profile object profileId is primaryKey and unique constraint is applied email field in Database table.
getProfile method is getting called from another Service MyService1 class and that service class method is being called from controller.
Now Issue what i am facing is even if i am passing a emailId in the method which is already available in the Database, profile object is being created and no exception is being caught in MyService1. Constraint violation Exception is only being caught in Controller where we are using created profile object further.
Exception message in controller is as follows:
org.springframework.dao.DataIntegrityViolationException: could not execute statement; SQL [n/a]; constraint [null]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement

When i pass profileId as null in getProfile method, then Exception is successfully being caught in MyService1 catch block.
Can anybody please explain me this behavior of CrudRepository Save method.
Thanks
