Tomcat在启动时突然抛出了一个ClassFormatError

Question

我的项目有问题,经过一些测试后我认为它与源无关.即使回到以前工作的版本,当我尝试部署到Tomcat时仍然会出错.

该错误是org.springframework.beans.factory.BeanDefinitionStoreException由java.lang.ClassFormatError消息Truncated类文件引起的.

我已经开始通过从等式中删除Eclipse来缩小问题,但即使使用maven命令行构建并直接部署到我的tomcat实例,我仍然会遇到同样的问题.人们建议清除tomcat工作和临时目录,谷歌搜索错误,我没有运气.

我知道这不是很多信息,但假设问题不在我的代码中,对我的系统进行哪些更改可能会导致此问题突然显现？

看起来其中一个类文件已损坏,但问题是找到哪一个.

调试此方法的一种方法是在异常功能上使用eclipse的break.启动tomcat以便它等待调试器在运行之前附加,然后在抛出的java.lang.ClassFormatError上中断,并查看eclipse中的局部变量和堆栈以查看哪个类无法加载.
