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
这样的问题是你的页面中含有<!---->的代码,由于tomcat是需要解析tld的,所以可能会抛出异常警告,但不会影响程序启动!
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。
