public class Test {
    public static void main(String[] args) {
        ResourceBundle res = ResourceBundle.getBundle("app", Locale.CHINA);
        System.out.println(res.getString("welcome.msg" ));
    }
}

//app_en_US.properties
welcome.msg=hello,sir

//app.zh_CHINA.properties
welcome.msg=u6b22u8fceu4f60uff01

2.Struts的资源文件

a)         Action – Package – App级

b)         一般只用APP

<constant name="struts.custom.i18n.resources" value="bbs2009"></constant>

c)         PropertiesEditor插件

                         i.              解压             

　　　　             ii.              features plugin 覆盖到myeclipse中的eclipse目录里

　　d)         动态语言切换

                         i.              request_locale=en_US

<form action="admin/Login-login" method="post">
      <s:property value="getText('login.username')"/> <input name="username" />
      <s:property value="getText('login.password')"/><input name="password" type="password" />
      <input type="submit" value="<s:property value="getText('login.login')"/>" /> 
  </form>
  <s:debug></s:debug>
  <a href="admin/lang?request_locale=en_US">en</a>
