問題描述
在tomcat啟動時打印出一句error日志,內容為:
24-Jul-2017 11:28:33.486 信息 [RMI TCP Connection(4)-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.
問題原因
這樣的問題是你的頁面中含有<!---->的代碼,由於tomcat是需要解析tld的,所以可能會拋出異常警告,但不會影響程序啟動!
解決方案
第一種：嚴格遵守java規范，修改對象的屬性名稱，要求不包含java關鍵字;
第二種：修改EL表達式，例如"${owner.new}"可以修改為"${owner['new']}";
第三種：修改tomcat屬性，忽略對EL表達式的關鍵字檢查。修改$CATALINA_BASE/conf/catalina.properties文件，添加org.apache.el.parser.SKIP_IDENTIFIER_CHECK=true選項。
