带hibernate登录的ASM（<；init>；（Z））

我在项目中使用hibernate作为数据库。它工作得很好，但现在我得到了这个例外

这是我在.xml文件中的hibernate配置：

导致此异常的原因是什么？如何停止它？

运行时环境中的asm.jar版本似乎与您的开发环境不匹配。比如说,

顺便说一句，我忍不住要发表评论——从JSP页面访问hibernate是一个非常糟糕的主意。您可能想看看如何使用一个像样的MVC框架，比如Spring MVC。

这里似乎有一些不兼容的JAR。你的项目中有哪些Hibernate和asm JAR？我同意。我确实认为，在视图中看到这一点是不好的做法。许多web开发人员不愿意遵循MVC模式。
