报错:
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.
检查自己的EL表达式是否书写正确 ， 大小写的错误有时还会很难看出来， 如果是服务器代码没问题 大多数都是EL表达式的错误运用 或者自己写的不规范， 一定要仔细检查EL 是否书写正确， 对象名称有没有拼错 ，因为EL书写错误他是不报具体的错的 就是报上面那一堆。。。。
