java - tomcat 服务器 webapp 启动时的无限负载

Question

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 启动时无限加载。

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。

这里是关于该问题的控制台日志。

Answer 1

如果您认为您的代码/配置没有错误，您是否尝试过检查 server.xml 和 web.xml 的正确配置？

此外，在您的 server.xml 中，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。
