IDEA發布應用時發布到lib下面的包不全,Tomcate啟動時就報: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
此時可能是包沒有全部發布到lib目錄引起的。具體看打下Project Structure->Artifacts點擊相應的項目點開lib文件夾看下面的jar包是不是紅色的，紅色的就是有問題的，把紅包的jar包添加到Output Root即可。
