问题描述

　　在tomcat启动时打印出一句error日志,内容为:

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.

问题原因

解决方案

　　第一种：严格遵守java规范，修改对象的属性名称，要求不包含java关键字; 
　　第二种：修改EL表达式，例如"${owner.new}"可以修改为"${owner[‘new‘]}"; 
　　第三种：修改tomcat属性，忽略对EL表达式的关键字检查。修改$CATALINA_BASE/conf/catalina.properties文件，添加org.apache.el.parser.SKIP_IDENTIFIER_CHECK=true选项。
