Tomcat を起動すると、この例外が発生します。

それ以外は、Tomcat は正常に動作しているようです。それでも、コンソールで例外が発生するのは好きではなく、Google 検索でも関連する結果が得られなかったので、助けていただければ幸いです。ありがとう

それ以来、Handler error私はあなたの tomcat に問題があると感じていますconf/logging.properties。

特に、そのファイルの最初の 2 行で不要なエントリを探します。デフォルトでは、これらは

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
