Question

我对多对多关系有疑问。

在这里我将粘贴代码

User.kt

@Entity
@Getter
@Setter
@Builder
@Inheritance(strategy = InheritanceType.JOINED)
@NoArgsConstructor
@AllArgsConstructor
@Table(name = "USER", schema = "public")
 data class User(
    @JsonView(Views.Base::class)
    var username: String,
    @JsonView(Views.UserExtended::class)
    @OneToMany(mappedBy = "user", cascade = [CascadeType.ALL], orphanRemoval = true)
    @JsonManagedReference
    var projects: List<UserProject>? = mutableListOf()

UserProject.kt

@Entity
@Getter
@Setter
@Builder
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "USER_PROJECT", schema = "public")
data class UserProject(
    @JsonView(Views.ProjectExtended::class)
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "user_id")
    val user: User?,
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "project_id")
    val project: Project?,
    @JsonView(Views.ProjectExtended::class)
    val projectRole: String
) : BaseEntity() {}

Project.kt

@Entity
@Getter
@Setter
@Builder
@NoArgsConstructor
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "PROJECT", schema = "public")
data class Project (
    @JsonView(Views.Base::class)
    val name: String?,
    @OneToMany(mappedBy = "project", cascade = [CascadeType.ALL], orphanRemoval = true)
    @JsonView(Views.ProjectExtended::class)
    var users: List<UserProject>?
) : BaseEntity() {}

我正在经历无限循环。我所做的只是简单地执行Views来解决问题。但是我也在@RepositoryRestResource上使用QueryDSL，这给了我关于URL的自动谓词问题是，我不能简单地将 @Jsonview 添加到RepositoryRestResource接口。

我尝试过进行投影，但是它给了我无限循环的结果，因为 @JsonView 在投影和界面上不起作用

有人建议我如何解决这个问题？
