Question

发送POST后

curl localhost：8888 / bills / addbill -H＆＃34; Content-Type：application / json＆＃34; -X POST -d＆＃39; {＆＃34; number＆＃34;：＆＃34; 111A111＆＃34;，＆＃34; customer＆＃34;：＆＃34; Customer Cuustomer Rrrr＆＃34;，＆＃ 34;电话＆＃34;：＆＃34; 1 800 5551212＆＃34;，＆＃34;经理＆＃34;：＆＃34;经理经理＆＃34;，＆＃34;日期＆＃34;：＆＃34 ; 2012-09-17＆＃34;，＆＃34; curId＆＃34;：{＆＃34; id＆＃34;：＆＃34; 1＆＃34;}，＆＃34;付款＆＃34;：[{ ＆＃34; id＆＃34;：＆＃34; 1＆＃34;，＆＃34; name＆＃34;：＆＃34; pomyit stekla＆＃34;，＆＃34; price＆＃34;：＆＃34; 1000.0＆＃34;}]}＆＃39;

我明白了：

我的实体中有多对多的关系＆＃34;比尔＆＃34;，这里是引发错误的字段。

付款实体：

    @ManyToMany
    @JoinTable(name="BILL_PAYMENTS",
        joinColumns=
        @JoinColumn(name="payments_id", referencedColumnName="id"),
        inverseJoinColumns=
        @JoinColumn(name="bills_id", referencedColumnName="id")
)
private List<Payment> payments = new ArrayList<>(0);

这是我的BillService文件：

@ManyToMany(mappedBy = "payments", cascade = {CascadeType.ALL}, fetch = FetchType.LAZY)
private List<Bill> bills = new ArrayList<>(0);

不知道发生了什么，我已经检查过stackoverflow上的类似问题，但它没有任何帮助。谢谢c：

Answer 1

您正在尝试保留与瞬态对象相关的对象，但您的付款未受管理，因此当您尝试保存帐单时，您将获得此例外。

解决方案1：您需要保存每笔付款并添加托管对象（从保存方法返回的对象）。

解决方案2：您可以将付款级联，以便在帐单持续存在时付款也会保留
