SpringMVC使用JsonView针对统一实体返回不同信息

public class UserDTO {
    //不显示地址
    public interface CommonView {}
    //显示地址
    public interface AdminView extends commonView {}
    @JsonView(value = CommonView.class)
    private String username;
    @JsonView(value = AdminView.class )
    private String address;
    //Getter Setter ...
}

    CommonView --> username

    AdminView |--> password
              |--> CommonView --> username

@RestController
@RequestMapping(value = "/user")
public class UserController {
    /**
     * 返回普通视图，不带地址
     * @return
     */
    @GetMapping(value = "/common")
    @JsonView(value = UserDTO.CommonView.class)
    public UserDTO getCommonView() {
        return new UserDTO("kingboy", "北京");
    }
    /**
     * 返回管理员视图，显示地址
     * @return
     */
    @GetMapping(value = "/admin")
    @JsonView(value = UserDTO.AdminView.class)
    public UserDTO getAdminView() {
        return new UserDTO("kingboy", "北京");
    }
}

{
"username": "kingboy"
}

{
"username": "kingboy",
"address": "北京"
}
