在选择客户请求时休眠无限循环

Question

这是我的模型类，当我使用此代码时，它将开始无限循环

Set<Request> requests = Clients.getRequest();

Answer 1

可能这个问题是因为@OneToMany 关系而发生的

在类Request的clients属性中添加注解@JsonIgnore：

@ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "clientid", nullable = false)
    @EqualsAndHashCode.Exclude
    @ToString.Exclude
@JsonIgnore
    private Client client;
