2014-7-13 17:36:57 org.apache.jasper.compiler.TldLocationsCache tldScanJar 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. 2014-7-13 17:36:59 org.apache.struts2.dispatcher.Dispatcher error 严重: Exception occurred during processing request: Unable to instantiate Action, com.you.user.action.StudentAction, defined for 'findStudent' in namespace '/action/student'Error creating bean with name 'com.you.user.action.StudentAction': Injection of resource dependencies failed;

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>
