当我尝试配置hibernate和java app（如何使用Jira服务）时，我有这个错误：

当我尝试为db启动SessionFactory时出现此错误：

ourSessionFactory = new AnnotationConfiguration().configure("hibernate.cfg.xml").addAnnotatedClass(Navision.class).buildSessionFactory();

Answer 1

包括其他版本的xerxesImpl通常是一个痛苦的方法。从您的应用中删除任何xercesImpl或xml-apis jar。

Answer 2

问题解决了。我找到了一些以前没见过的因素。这些是包含在自定义lib中的解析器，hibernate.core，dom4j等等。
