的Tomcat Web应用程序的启动过程中挂起

问题描述：

我web项目被正常使用，它包括：spring3和Hibernate3的。由日食重构的帮助日食重命名一些包后，tomcat的便无法启动了。它挂在下面这些日志：的Tomcat Web应用程序的启动过程中挂起

它挂在这里，当Tomcat的 “启动超时” 达到tomcat的停止。我增加了超时为100秒，但它是无用的，其中应用仍挂在最长的时间！最奇怪的是，没有任何错误，它只是挂起。我尝试了很多次清理/删除服务器和清理/构建项目，但没有结果。

我可以得出以下结论：

它总是相同春天的HashMap在单模式试图获取一个bean并不能找到这个原因线程是锁定 ...非常非常奇怪！不得有对一个例外或超时抛？奇怪的春天架构！

不显示只是INFO日志，但错误 – Xorty 2012-02-29 09:59:13

30或60秒后会超时吗？它可以连接到数据库？ – mindandmedia 2012-02-29 09:59:17

从工作区中删除该tomcat并添加一个新的，然后再试一次:) – 2012-02-29 10:00:31

答

OK我解决了这个：日食重构没有改变春 <context:component-scan base-package="package_name" />块，因此春天找不到任何有线部件来对待。我通过添加Spring Tools -> add java nature并检入发现此问题。弹簧浏览器选项卡context:component-scan块为空。

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

那么......自动装配失败了，因为它正在扫描错误的软件包？ – 2012-03-01 13:47:46

@DonalFellows它正在扫描不存在的软件包。 – GingerHead 2012-03-01 13:54:51

_Spring_中存在一个错误，它不检查'context：component-scan'块中的包名是否存在。在运行时，它不会抛出任何异常，并继续在它的hashmaps中搜索不存在的软件包！ – GingerHead 2012-03-01 14:04:20

答

你可以尝试以下方法：

启用调试日志记录 - 这会给你一个更好地了解服务器正在做什么。
检查数据库中的打开连接以查看连接是否建立。
当进程处于此状态时，创建线程转储。有关如何执行线程转储的详细信息，请参阅here或here。

Tomcat的服务器窗口具有焦点我按CTRL +休息，它打印出线程转储，现在我试图分析输出... – GingerHead 2012-02-29 12:38:36

转到tomcat /日志，看一看catalina.log，localhost.log ，stdout.log，stderr.log。 – AlexR 2012-02-29 12:48:19

检查长堆栈轨迹（比少数几行更长），可能还包含对Spring，数据库驱动程序或网络/套接字类的一些引用。这些是这类阻滞剂的常见来源。这可能是一个网络超时问题或数据库问题... – nwinkler 2012-02-29 12:52:39
