WEB-INF/classes目錄下新建一個文件叫logging.properties
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
我們再啟動tomcat時，就會在logs目錄下生成一個更詳細的日志error-debug.xxx.log
查看運行日志
、先切換到：cd tomcat/logs 2、tail -f catalina.out 3、這樣運行時就可以實時查看運行日志了
