Tomcat报的错太含糊了,什么错都没报出来,只提示了Error listenerStart。为了调试,我们要获得更详细的日志。可以在WEB-INF/classes目录下新建一个文件叫logging.properties,内容如下
- handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
- ############################################################
- # Handler specific properties.
- # Describes specific configuration info for Handlers.
- ############################################################
- org.apache.juli.FileHandler.level = FINE
- org.apache.juli.FileHandler.directory = ${catalina.base}/logs
- org.apache.juli.FileHandler.prefix = error-debug.
- java.util.logging.ConsoleHandler.level = FINE
- java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
这样,我们再启动tomcat时,就会在logs目录下生成一个更详细的日志
