Struts2国际化

资源文件命名规范
baseName_language_country.properties//全局范围的命名规则
Hello_en_US.properties
Hello_zh_CN.properties

package_language_country.properties//包内的命名规则
package_en_US.properties
package_zh_CN.properties

ActionClassName_language_country.properties//只对Action有效的的命名规则
HelloWordAction_en_US.properties
HelloWordAction_zh_CN.properties

系统查找顺序为 ActionClassName_language_country.properties——》package_language_country.properties——》baseName_language_country.properties
        即从 Action——》包内的——》全局范围的
如果当前包内没有，则往上层包寻找
