Tomcat 8.5.29啓動報TldScanner.scanJars錯誤問題解決辦法

Tomcat 8.5.29啓動過程當中的錯誤信息：

16-Mar-2018 09:28:45.505 信息 [RMI TCP Connection(3)-127.0.0.1] org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

網上不少人都遇到，當時沒有什麼從根本上解決的辦法。這裏解決也僅僅是經過調整tocmat日誌級別來控制日誌輸出信息。

在apache-tomcat-8.5.29\conf目錄下找到logging.properties文件，對文件進行編輯，在最後一行加入：

org.apache.jasper.servlet.TldScanner.level = FINE

這樣就再也不顯示錯誤信息了。
