这是在运行mvn依赖项：tree之后得到的， 我检查了我对cglib的依赖，但我不确定版本是否兼容，请检查让我知道哪些兼容我的项目。

3 个答案:

答案 0 :(得分：1)

对于cglib，你可能会错过一个jar。

这是什么时候发生的（unitTest，已部署）？ 你如何建立你的项目（Maven，ant）？哪个版本的Hibernate？没有一些信息很难帮助你。

编辑：尝试运行mvn dependency:tree并在此处发布结果，我们应该看看有什么问题

编辑：你有2个版本的cglib。你不应该手动包含cglib，因为它已经被hibernate包含为传递依赖。

答案 1 :(得分：0)

只需检查项目中有多少cglib JAR。尝试确保对于您的项目+框架版本，您有所需的cglib JAR而不是一些额外的JAR浮动。

答案 2 :(得分：0)

你在课程路径上错过了什么。这就是它显示“MappableContainerException”的原因。此异常与数据库管理器有关。那么请你停止服务器，清理并重新部署它。感谢。
