Tomcat在webapp启动期间挂起

我的网络项目运行正常，它包括： spring3 和 hibernate3 。在 eclipse重构的帮助下重命名 eclipse 中的一些软件包之后， tomcat 就无法启动了。它挂在以下这些日志中：

它挂起，当 tomcat的“启动超时”到达 tomcat 时停止。我将超时时间增加到100秒，但它没用， app 仍然在最长时间内挂起！ 最奇怪的是，没有任何错误，只是挂起。我多次尝试清理/删除服务器并清理/构建项目，但没有结果。

修改

在重构日志之前，如下所示：

我得到了一个带有以下输出的线程转储：

我可以得出以下结论：

在 singleton 模式下，它始终是相同的 spring hashmap，试图获取bean并且由于该原因而无法找到该线程已锁定 ......非常奇怪！ 异常或超时不能有抛出吗？奇怪的 Spring 架构！

好的我解决了这个问题： eclipse重构 没有改变 Spring <context:component-scan base-package="package_name" />阻止因此 spring 无法找到要处理的任何有线组件。我发现这是通过添加Spring Tools -> add java nature并在 Spring Explorer 标签中检查context:component-scan块为空的。

感谢AlexR，mindandmedia，NIVESH SENGAR，Xorty和Donal Fellows的支持，特别感谢nwinkler的建设性指示！

您可以尝试以下方法：

  • 启用DEBUG日志记录 - 这将使您更好地了解服务器正在执行的操作。
  • 检查数据库是否已建立连接，以查看是否已建立连接。
  • 当进程处于此状态时创建线程转储。有关如何进行线程转储的详细信息，请参阅here或here。
