从多对多spring jpa关系中获取正确的查询以获取学生课程

@Entity
public class Student {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    private String name;
    
    @ManyToMany(cascade = CascadeType.ALL)
    @JoinTable(name = "student_course",
               joinColumns = @JoinColumn(name = "student_id"),
               inverseJoinColumns = @JoinColumn(name = "course_id"))
    private Set<Course> courses = new HashSet<>();
    
    // 省略构造方法、getter和setter
}

@Entity
public class Course {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    private String name;
    
    @ManyToMany(mappedBy = "courses")
    private Set<Student> students = new HashSet<>();
    
    // 省略构造方法、getter和setter
}

public interface StudentRepository extends JpaRepository<Student, Long> {
    Set<Course> findCoursesById(Long studentId);
}

@Service

    @Autowired
    private StudentRepository studentRepository;
    
    public Set<Course> getCoursesByStudentId(Long studentId) {
        return studentRepository.findCoursesById(studentId);
    }
}
