信息: 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.

2、错误原因

    因为配置applicationContext.xml时，未将其配置到web.xml中

3、解决的方法

    在web.xml中加入一段xml代码：

<context-param>
	<param-name>contextConfigLocation</param-name>
	<param-value>
           classpath*:applicationContext*.xml,
           classpath*:applicationContext.xml
    </param-value>
</context-param>
