spring-data-rest @ManyToMany

Question

I am working on a spring-data-rest module, but there is a problem in the query process: I defined the roles attribute in the User class, added @ManyToMany annotation, and printed relevant sql about the Role during execution, but there was no relevant information about the Role in response. How should I query my role information as well?

Here is my code: user class:

@Entity(name = "user")
public class User implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @ManyToMany(targetEntity = Role.class,cascade = CascadeType.MERGE,fetch = FetchType.EAGER)
    @JoinTable(name = "user_role",
            joinColumns = {@JoinColumn(name = "user_id", referencedColumnName = "id")},
            inverseJoinColumns = {@JoinColumn(name = "role_id", referencedColumnName = "id")}
    )
   private Set<Role> roles = new HashSet<>();
}

role class:

@Entity(name = "role")
public class Role implements Serializable {
    @Id
    private Long id;

    @ManyToMany(mappedBy = "roles",cascade = CascadeType.MERGE)
    private Set<User> users = new HashSet<>();

UserRepository class:

@RepositoryRestController
public interface UserRepository extends JpaRepository<User,Long>, JpaSpecificationExecutor<User> {
    @RequestMapping(value = "findByUsername",method = RequestMethod.GET)
    User findByUsername(@RequestParam String username);
}

this is my response in postman: enter image description here

so,why can't I get the role information in user?
