Tomcat:一个或多个听众未能启动

Question

我有一个应用程序,在我添加/升级​​一些依赖项后没有启动.它记录错误说

SEVERE: One or more listeners failed to start. Full details will be found in the appropriate container log file

我看到了所有日志文件和catalina.,localhost.,application.*,但它们似乎都没有堆栈跟踪,因为启动正在破坏.

这是tomcat8,java8.

如何检查日志以及日志在正常tomcat文件夹之外的位置.

Catalina日志:

Answer 1

找到了一种识别问题的简单方法.

1. 在WEB-INF/classes应用程序的目录中,创建一个新文件:logging.properties.

2. 在该文件中添加以下内容:

org.apache.catalina.core.ContainerBase.[Catalina].level=INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers=java.util.logging.ConsoleHandler

3. 重启tomcat.

现在,您将拥有完整的堆栈跟踪并从那里调试问题.

Answer 2

添加logging.properties文件对我没有任何作用。而是在tomcat/logs/localhost.[YYYY-MM-DD].log.
