eclipse启动tomcat，不能够加载项目，并且控制台有如下信息输出：
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.
大致原因是某个地方的EL表达式写的不正确，有很多处理方法。
我采用比较快速的解决方法，就是忽略这种检查。
找到catalina.properties文件
添加最后一行
org.apache.el.parser.SKIP_IDENTIFIER_CHECK=true
，重启tomcat。
