tomcat 服务器 webapp 启动无限负载
Infinite load on tomcat server webapp startup
我从 ToolTwist 8.1 升级到 ToolTwist 8.5 时遇到了一个奇怪的错误。
错误是 tomcat 服务器 webapp 启动时的无限负载。
我认为加载配置没有错误，因为我在控制台上看到 Tooltwist Startup Commencing，这意味着 tooltwist 库已经启动。
这里是关于这个问题的控制台日志。

TIA
如果您认为 code/configuration 没有错误，您是否尝试检查 server.xml 和 web.xml 的正确配置？
另外，在您的 server.xml 上，请检查 Context 标签上的 reloadable 是否设置为 false。这将阻止 catalina 持续检查更改并防止它再次重新加载 webapps。我认为问题出在这里。
