Question

当我调用Session.persist传递一个具有多个问号的String属性的实体对象时，我得到如下所示的异常。

异常似乎发生是因为hibernate在预准备语句中使用问号作为值占位符。

有人知道这个问题的解决方法吗？

这里是触发异常的对象的字符串表示：

WcmsPart [mpn = 04EAC2 ??? 16-001，cpn = null，description = PRIMER POLYURETHANE PAINT，数量= 1，......]

以下是例外情况。感谢您的建议

问号应该是Hibernate / SQL中的参数。因此，在保存数据之前，您需要将其转义

字符串字段包含问号
