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.

    由于配置applicationContext.xml时，未将其配置到web.xml中

3、解决办法

    在web.xml中添加一段xml代码：

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