java - Tomcat7:WAITING WAR 文件的多线程部署完成时出错

Question

Tomcat 7.0.30 启动失败(无法启动)，出现以下异常:

SEVERE: Error waiting for multi-thread deployment of WAR files to complete

以下是异常的完整堆栈跟踪:

注意cfwd.war是webapps目录下唯一的war文件(除了通常的默认内容，如examples， 经理等)。

对此的可能原因有什么想法吗？

Answer 1

这通常是由应用程序类层次结构问题引起的。我见过的一个例子是过时的类引入了循环继承。

如果升级到 7.0.47，您将收到有关问题所在的更多信息性错误消息。或者，您的应用程序的干净构建可能足以清理一切。
