解决方法一:

<filter-name>struts2</filter-name>

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

<init-param>

<param-name>config</param-name>

<param-value>struts-default.xml,struts-plugin.xml,struts2/struts-*.xml</param-value>

</init-param>

</filter>
即设置初始化参数时加载以下文件：struts-default.xml(必须),struts-plugin.xml(可选)二个额外的配置文件.
原因:
struts-default.xml是默认配置文件,一些必须的框架参数都默认设置在此配置文件中.

解决方法二：

直接将自己的配置文件struts.xml的名称改为struts-default.xml，然后再将struts源文件中的struts-default.xml引入进自己的配置文件中

用<include file="struts-default.xml"/>，如果你的配置文件中需要返回json数据，那么要将json-default依赖的文件“struts-plugin.xml”也引入进去。

解决方法三（最终解决方法）：

其实这个错误的意思是找不到“com.opensymphony.xwork2.LocaleProvider”的配置文件映射，只所以会报这个错是因为在实现进度条时重写的JakartaMultiPartRequest类中保留了：

@Inject
public void setLocaleProvider(LocaleProvider provider) {
defaultLocale = provider.getLocale();
}

这段代码要求struts的配置文件中要有LocaleProvaider的映射提供，如果strut2.xml中没有配置该文件就会报这个错......

解决方法：在自己重写的JakartaMultiPartRequest文件中将上面的那段代码删除就可以了、、、（解决方法一、二都可以不用做了！）
