## 1、场景 ##

struts2 照片上传功能后天报错如3

## 2、解决办法 ##

由于struts2升级导致其有些方法不可用了，解决办法是

1、使用2.3.15以后的版本（比如2.3.16）的xwork和struts-core的包

2、web中应用的struts2的filter的类路径改为

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

而不是原先的

<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>

## 3、报错内容 ##
