Javassist Enhancement失败了

Question

我使用Jboss IDE作为IDE。我创建了一个Hibernate项目。部署我的.har（Hibernate项目）时出现此错误：

Answer 1

堆栈跟踪非常复杂，您最好在JBoss邮件列表/论坛上向JBoss开发人员询问，或者打开错误报告（假设存在java.lang.NullPointerException，这肯定是一个错误）。

无论如何，鉴于错误报告在：

org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:623)

在课程加载过程中遇到问题，同时寻找一些课程。 您可以查看org.jboss.mx.loading.RepositoryClassLoader（第623行）的来源，看看您是否找到了有用的内容，或直接在其他地方寻求支持。

Answer 2

当你得到堆栈跟踪时：

java.lang.NullPointerException
 at org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:623)

这通常意味着JBoss的类加载器已进入不可恢复状态，并且某些核心类的加载失败，这偶尔会在大量热部署之后发生。

根据我的经验，它通常由JBoss重启来修复。

Answer 3

您应该在hibernate.cfg.xml

中使用此属性

<property name="hibernate.bytecode.use_reflection_optimizer">false</property>

如果没有理由使用javaassit.jar，应该从项目构建路径中删除该jar文件，所有这些都可以轻松解决，因为我已经解决了这个问题。
