Question

我使用cfg文件和错误日志发布我的hbm文件。我发现基于类似问题的问题也尝试了他们的解决方案，但我的错误仍然没有消失。

Answer 1

在long startTime = System.currentTimeMillis(); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(startTime); calendar.add(Calendar.MINUTE, 90); System.out.println(calendar.getTime());中，您没有关闭生成器代码。替换

Employee.hbm.xml

由此

<generator class="native">

Answer 2

通过查看堆栈跟踪，您没有正确结束生成器标记。

请更改您的employee.hbm.xml文件以正确结束<generator>元素。

对于Ex：它应该是<generator class="native"/>

hibernate.hbm.xml中的映射异常无效
