Struts中像这种全局错误能否进行封装？
例如像以下代码：
public   ActionForward   execute(ActionMapping   mapping,
    ActionForm         form,
    HttpServletRequest   request,
    HttpServletResponse   response){
    String   action   =   request.getParameter( "action ");
    if( "111 ".equals(action))
    {
              ActionMessages   messages   =   new   ActionMessages();
              ActionMessage   message   =   new   ActionMessage( "error1 ");
              messages.add(ActionMessages.GLOBAL_MESSAGE,message);
              saveMessages(request,messages);
              return   mapping.findForward( "error1 ");
    }
    else   if( "222 ".equals(action))
    {
              ActionMessages   messages   =   new   ActionMessages();
              ActionMessage   message   =   new   ActionMessage( "error2 ");
              messages.add(ActionMessages.GLOBAL_MESSAGE,message);
              saveMessages(request,messages);
              return   mapping.findForward( "error2 ");
    }
    return   mapping.findForward( "ok ");
}

如果这种判断很多，那代码就会显得很长，也很乱，能不能把
              ActionMessages   messages   =   new   ActionMessages();
              ActionMessage   message   =   new   ActionMessage( "error1 ");
              messages.add(ActionMessages.GLOBAL_MESSAGE,message);
              saveMessages(request,messages);
              return   mapping.findForward( "error1 ");
的代码块封装起来，然后再调用？

可以呀，把这段代码写到一个函数中，参数ActionMapping mapping, HttpServletRequest request,
为参数
