how to query the relation in spring boot?

I want to get students for a teacher where the student's age is larger than 18.

I used to work with Laravel framework, where I was able to do this by:

$AdultStudents = $teacher->students->where('age'>18);

Is there a way to do this in Spring Boot without using the mysql query? I mean using a single method from JPA Repository. Let us say something like this:

teacher.getStudents().whereAgeGreaterThan(18);

Yes, supposing you have your JPA Spring Data Repo you can construct the query by naming method as per the Spring Data query method rules passing the value as a method parameter.

In your example inside the Studends DAO supposing the Student has an age attribute a method named:

findByAgeGreaterThan(Integer age)
