Question

假设我在Hibernate的批处理操作中插入100行，类似于：

beginTx with flush mode manual;

insert 100 rows;
do 100 times {
    insert row
    commit;
}
flush;
clear;

理想情况下，这应该转换为批处理操作（因为批量大小的参数，由Hibernate设置的键等）。但是假设批处理中的一个插入在FK约束上失败，或者其他什么。已提交单个行，但仅在刷新期间出现问题（约束违规）。

这种情况可能吗？（我100％肯定这是到现在为止发生的事情）如果是这样，我应该担心它，还是JDBC或Hibernate负责业务？处理此问题的最佳方法是什么？

感谢。
