org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

严重: Exception starting filter struts2
java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

 

struts2中StrutsPrepareAndExecuteFilter 异常如果是2.1.3之前的版本用org.apache.struts2.dispatcher.FilterDispatcher，否则用org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter。  

因为从Struts2.1.3开始，将废弃ActionContextCleanUp过滤器，而在StrutsPrepareAndExecuteFilter过滤器中包含相应的功能。在web.xml中做修改红色字体部分    
    
<filter>  
    <filter-name>struts2</filter-name>  
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
找不到类，在你的JAVA程序中类或方法内部写StrutsPrepareAndExecuteFilter
然后alt+/快捷键，导入这个类，再看你的import里面与之有关的代码，把它复制到你的web.xml中
