无法在 Eclipse Luna 中启动 Tomcat 7.0

Question

我必须开始处理我安装了 Eclipse Luna 和 Tomcat 7.0 的网络应用程序项目。该环境也有 JRE 8。但是每当我启动服务器时，它就会超时！

在控制台中我得到：

nov. 20, 2014 11:08:20 PM org.apache.catalina.core.AprLifecycleListener init

我已经尝试过此论坛上其他问题中提出的解决方案，例如延长超时期限、更改端口号、卸载和重新安装 Tomcat、更改服务器的“发布”选项，但似乎没有任何效果。

任何帮助将不胜感激。

超时意味着 Tomcat 没有进入您的应用程序已完成启动的阶段。否则，它将向 Eclipse 发出成功或失败的信号。由于最后一行是关于 Spring 初始化许多 bean，我的第一个想法是你有一些构造后初始化程序（@PostConstruct，InitializingBean.afterPropertiesSet）挂在无限循环或死锁上。

检查您自己的 bean（studentController、studentDaoImpl、studentServiceImpl）是否有挂起的初始化程序。也许创建一些初始化程序（使用@PostConstruct，它更简单）并添加一些日志输出以确保您的 bean 实际被初始化。如果您可能不得不将超时设置为 20-30 分钟或更长时间，请获取您正在使用的版本的 Spring 源代码，并实际逐步执行 Spring 的初始化代码。看起来它甚至没有进入 sessionFactory（我假设它是用于 Hibernate）。
