如何仅在春季返回特定字段

Question

在下面的代码中，当我使用投影时，它返回了我的整个对象组，但我只想得到roleName类Group 我该怎么做？

投影：UserWithProfile

@Projection(name="UserWithProfile",types=User.class) 
public interface UserWithProfile extends UserGetters { 
    UserPhoto getProfilePhoto(); 
} 

UserGetters

public interface UserGetters{ 

    Long getId(); 
    String getName(); 
    String getLogonEmail(); 
    boolean isEmailVerified(); 
    Group getGroup(); 
} 

User.class

@Entity 
public class User implements Serializable, UserGetters { 
    private static final long serialVersionUID = 1L; 

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

    @ManyToMany(cascade = CascadeType.REMOVE, fetch = FetchType.EAGER, targetEntity = Property.class) 
    private Set<Property> favouriteProperty; 

    @OneToOne 
    private AcceptanceLetter acceptanceLetter; 

    @Column(unique=true) 
    private String logonEmail; 


    private String name; 

    @JsonProperty(access = Access.WRITE_ONLY) 
    @Column(updatable=false) 
    private String password; 


    private boolean emailVerified; 

    @ManyToOne 
    private Group group; 

    @OneToOne 
    private Business business; 

    private String address; 

    private String postcode; 

    private String phoneNo; 

    private String passportNo; 


    @Column(length=1000) 
    private String description; 


    @JsonIgnore 
    private float meanRating; 


    @OneToOne(mappedBy="user",targetEntity=UserPhoto.class) 
    private UserPhoto profilePhoto; 

    @ManyToOne 
    private Country country; 
    Getter and setters... }

首先我试过@RestResource(exported = false)它没有工作，但后来我试图 @JsonIgnore它终于工作：'D
