[英]java.nio.charset.MalformedInputException: Input length
[英]java.nio.charset.MalformedInputException: Input length = 1
我有一個zip文件,我需要允許用戶使用支持UTF-8的Java 1.6從部署在Tomcat 6上的JSF應用程序下載。以下是我的jsp頁面上的代碼:
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());
}
它曾經在不支持UTF-8時起作用。 現在,我不斷收到以下異常。 為什么輸出流ByteArrayWebOutputStream需要使用解碼器? 我能找到的大多數建議是處理InputStream的編碼,而不是異常指示的OutputStream。 我怎樣才能解決這個問題?

我確實將CharsetFilter用作管道的一部分,但是似乎沒有任何影響,因為我從過濾器目標中刪除了URL,結果仍然相同。
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);
}
