tomcat - 启动Tomcat时出现异常

Question

启动 Tomcat 时出现此异常。

除此之外，Tomcat 似乎运行正常。不过，我不喜欢我的控制台出现异常，我的 Google 搜索也没有找到相关结果，因此非常感谢您的帮助。谢谢

这是我在 logging.properties 文件中得到的内容:

handlers = startup
.handlers = startup, java.util.logging.ConsoleHandler

############################################################
# Handler specific properties.
# Describes specific configuration info for Handlers.
############################################################

startup.level = FINE
startup.directory = ${catalina.base}/logs
startup.prefix = startup.

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

Answer 1

因为它说 Handler error 我感觉你的 tomcat 的 conf/logging.properties 有问题。

特别要查找该文件前两行中的任何杂散条目。默认情况下，这些是

handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler,
 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, 
java.util.logging.ConsoleHandler

.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
