		使用jakarta commons-upload。 
          升級(jí)到2.2.2后發(fā)現(xiàn)上傳中文會(huì)亂碼。 
          經(jīng)過(guò)跟蹤發(fā)現(xiàn)在com.opensymphony.webwork.dispatcher.DispatcherUtils的prepare(HttpServletRequest request, HttpServletResponse response)方法。 
          2.2.1->2.2.2時(shí)這個(gè)方法發(fā)生了非常的的變化。 
          2.2.1時(shí)：?
          public?void?prepare(HttpServletRequest?request,?HttpServletResponse?response)?{?
          ????????          if?(encoding?!=?null)?{?
          ????????????          try?{?
          ????????????????request.setCharacterEncoding(encoding);?
          ????????????}?          catch?(Exception?e)?{?
          ????????????????LOG.error(          "Error?setting?character?encoding?to?'"?+?encoding?+?"'?-?ignoring.",?e);?
          ????????????}?
          ????????}?

          ????????          if?(locale?!=?null)?{?
          ????????????response.setLocale(locale);?
          ????????}?

          ????????          if?(paramsWorkaroundEnabled)?{?
          ????????????request.getParameter(          "foo");?//?simply?read?any?parameter?(existing?or?not)?to?"prime"?the?request?
          ????????}?
          ????}
          
		
				
          2.2.2時(shí)： 
          public?void?prepare(HttpServletRequest?request,?HttpServletResponse?response)?{?
          ????????String?encoding?          =?null;?
          ????????          if?(Configuration.isSet(WebWorkConstants.WEBWORK_I18N_ENCODING))?{?
          ????????????encoding?          =?Configuration.getString(WebWorkConstants.WEBWORK_I18N_ENCODING);?
          ????????}?

          ????????Locale?locale?          =?null;?
          ????????          if?(Configuration.isSet(WebWorkConstants.WEBWORK_LOCALE))?{?
          ????????????locale?          =?LocalizedTextUtil.localeFromString(Configuration.getString(WebWorkConstants.WEBWORK_LOCALE),?request.getLocale());?
          ????????}?

          ????????          if?(encoding?!=?null?&&?!MultiPartRequest.isMultiPart(request))?{?
          ????????????          try?{?
          ????????????????request.setCharacterEncoding(encoding);?
          ????????????}?          catch?(Exception?e)?{?
          ????????????????LOG.error(          "Error?setting?character?encoding?to?'"?+?encoding?+?"'?-?ignoring.",?e);?
          ????????????}?
          ????????}?

          ????????          if?(locale?!=?null)?{?
          ????????????response.setLocale(locale);?
          ????????}?

          ????????          if?(paramsWorkaroundEnabled)?{?
          ????????????request.getParameter(          "foo");?//?simply?read?any?parameter?(existing?or?not)?to?"prime"?the?request?

          我看了jira沒(méi)有發(fā)現(xiàn)encoding != null && !MultiPartRequest.isMultiPart(request)這個(gè)判斷的意義。但是它會(huì)造成對(duì)multiPartRequest的encoding判斷失敗，中文就會(huì)亂碼。 
          所以臨時(shí)的解決方案是將判斷改成： 
          if (encoding != null) 

          聽(tīng)說(shuō)WW的Jira已經(jīng)不接受新issue了，不知是否真的？ Crying or Very sad

						用了一個(gè)比較苯的辦法

          自己寫了個(gè)FileUploadInterceptor

          加了個(gè)方法：

          	private Map reEncode(Map parameters) throws IOException{

              	String keys = "";

              	byte [] temp_t = new byte[]{};

              	Set entries = parameters.keySet();

              	Iterator it = entries.iterator();

              	while (it.hasNext()){

              		keys = (String)it.next();    

              		if (parameters.get(keys)!=null && parameters.get(keys) instanceof java.lang.String[]){

              			temp_t = ((String[])parameters.get(keys))[0].getBytes("ISO8859_1");

              			parameters.put(keys, new String(temp_t,"GBK"));

              		}

              	}

              	return parameters;

              }

          然后在下面這個(gè)地方用一下：

						呵呵，其實(shí)我覺(jué)得不如上面說(shuō)的那個(gè)解決徹底。因?yàn)閱?wèn)題就出在上面描述的位置，我去Webwork論壇問(wèn)了，他們也說(shuō)問(wèn)題就在這里，現(xiàn)在只需if (encoding != null) 然后每次都request.setCharacterEncoding(encoding);就可以了，不需要手工轉(zhuǎn)碼。  回復(fù)  更多評(píng)論
