我有一個zip文件,我需要允許用戶從使用支持UTF-8的Java 1.6的Tomcat 6上部署的JSF應用程序進行下載。以下是我的jsp頁面:java.nio.charset.MalformedInputException:輸入長度= 1
File downloadFile = new File(filePath+ "/" +zipfileName)
try {
response.setContentType("APPLICATION/OCTET-STREAM");
response.setHeader("Content-Disposition","attachment; filename=\""+ +zipfileName;+ "\"");
//stream out file
FileInputStream fInputStream =new FileInputStream(downloadFile);
ServletOutputStream fOutputStream = response.getOutputStream();
int i;
while ((i=fInputStream.read()) != -1) {
fOutputStream.write(i);
}
fInputStream.close();
fOutputStream.close();
} catch (Exception exp){
System.out.println("Exception: "+exp.getMessage());
}
它在UTF-8不支持時用於工作。現在我不斷收到以下異常。爲什麼輸出流ByteArrayWebOutputStream需要使用解碼器?我能找到的大部分建議是處理InputStream的編碼,但不處理異常所示的OutputStream。我怎樣才能解決這個問題?

我使用一個CharsetFilter作爲管道的一部分,但似乎因爲我移除了過濾器的目標,結果還是一樣的URL是對形勢沒有任何影響。
public void doFilter(ServletRequest request, ServletResponse response, FilterChain next)
throws IOException, ServletException
{
// Respect the client-specified character encoding
// (see HTTP specification section 3.4.1)
if(null == request.getCharacterEncoding())
request.setCharacterEncoding(encoding);
/**
* Set the default response content type and encoding
*/
response.setContentType("text/html; charset=UTF-8");
response.setCharacterEncoding("UTF-8");
next.doFilter(request, response);
}
你使用任何特定的字符集? – Rehman
不,我有幾個xls和txt文件壓縮在一起作爲測試。但我的網站啓用了UTF-8,即每個頁面支持utf-8,Web應用程序的所有方面都可以處理utf-8等。我確實有一個Charset過濾器。 – jCoder
