- 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?
一些遗留代码表现出奇怪的行为。我有一个 Hibernate 标准:
Session session = em.unwrap(Session.class);
Criteria crit = session.createCriteria(Db.ZIPCODE_REF.CLASS);
crit.add(Restrictions.eq(Db.ZIPCODE_REF.ZIP_MIN, zipRef.getZipMin()));
crit.add(Restrictions.eq(Db.ZIPCODE_REF.ZIP_MAX, zipRef.getZipMax()));
crit.add(Restrictions.eq(Db.ZIPCODE_REF.REFERENTIEL, zipRef.getReferentiel()));
List<ZipcodeRef> list = crit.list();
list() 方法因以下异常而结束:

查看 Hibernate 日志,它似乎在以下查询上崩溃:
update ZIPCODE_REF set BU_ID=?, COMMUNE=?, DESCRIPTION=?, PAYS_ID=?, REFERENTIEL_ID=?, ZIP_MAX=?, ZIP_MIN=?, PARENT_ID=? where ID=?
这对我来说完全没有意义。我正在尝试根据条件获取对象列表,而不是更新任何内容。有什么想法吗?
编辑:这似乎是在选择之前进行的一些缓存刷新。很难找到错误更新的位置。如果有人至少可以解释我如何查看更新的参数值,那将是一个很大的帮助。
最佳答案
在执行 Criteria 查询之前,必须执行一条更新语句(但尚未提交到数据库)。如果查看 stackstrace,您可以看到查询导致刷新
at org.hibernate.internal.SessionImpl.autoFlushIfRequired(SessionImpl.java:1099)
at org.hibernate.internal.SessionImpl.list(SessionImpl.java:1528)
刷新然后会导致 hibernate 将更新实际写入数据库。此时数据库会提示某个值对于列而言太大。
因此,您必须在执行 Criteria 查询之前检查正在运行的代码。
