liferay 如何 用 国际化

1 首先写三个language.properties文件如下图

2 传入参数判断 为哪一种语言

  String editon = request.getParameter("editon") == null ? "e" : request.getParameter("editon");
     String separator=File.separator;
     String path="en_US";
     if(editon.equals("e"))
     {
        path="en_US";
     }
     else if(editon.equals("s"))
     {
        path="zh_CN";
     }else if(editon.equals("t")){
       path="zh_tw";
     }

3 初始化配置取出相应的值得

 String paths =  this.getServletContext().getRealPath("/") +"language" + separator + path + separator +"language.properties";
     System.out.println( " add_user_alert_rulers.jsp paths = " + paths);
     VtcMessage msg = new VtcMessage(paths);
     InternationalUtil international=new InternationalUtil();
