- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我的账户中有:
@OneToMany(mappedBy = "accountId", fetch = FetchType.EAGER, cascade = {CascadeType.REMOVE, CascadeType.PERSIST})
private Set<AuthAccountMail> authAccountMails;
在 AuthAccountMail 中我有:
@Id
@ManyToOne(fetch = FetchType.EAGER, targetEntity = Account.class, optional = false)
@JoinColumn(name="ACCOUNT_ACCOUNT_ID")
private Account account;
当我尝试进行查找时,出现了 stackoverflow 错误,因为它们开始相互加载。
有问题的查询如下:
@Query("SELECT a FROM Account a INNER JOIN FETCH a.authAccountMails aam INNER JOIN FETCH aam.mail m INNER JOIN FETCH aam.authIsle i WHERE a.cancelled = false and m.email = :mail and i.code = :isleCode")
Account findAccountByMailAndIsleCode(@Param("mail") String mail, @Param("isleCode") String isleCode);
这个在 stackoverflow 中。你认为有办法解决这个问题吗?我们尝试将两者之一设置为 LAZY,但由于我们没有找到 @Transactional,如果我们尝试调用 authAccountMails,我们会收到错误,因为我们试图在事务之外延迟加载它。
现在我们解决了在 Account 内的 authAccountMail 上放置一个 LAZY 并在 AuthAccountMail 内的帐户上放置一个 EAGER,通过设置 find @Transactional 但绝对不喜欢它。
我们正在使用 Hibernate 4.3.5
你能给我一些建议吗?

最佳答案
在您的实体中,您必须排除与您有关系的实体的 toString、hascode 和 equals 方法,因为如果没有,他们将开始尝试创建 toString 并使用与您有关系的实体,而这个将对你做同样的事情然后......不定式循环和堆栈溢出。
在Spring中我使用注解
@ToString(exclude = {"B"})
@EqualsAndHashCode(exclude = {"B"})
class A{}
@ToString(exclude = {"A"})
@EqualsAndHashCode(exclude = {"A"})
class B{}
