我从服务器下载文件的代码存在问题。它看起来像这样：

    response.reset();
    response.setContentType("audio/vnd.wave");
    File file = new File(filename);
    FileInputStream stream = new FileInputStream(file);
    long toWrite = file.length();
    filename = filename.substring(filename.lastIndexOf(File.separator) + 1, filename.length());
    response.setHeader("Content-disposition", "attachment; filename=\"" + filename + "\"");
    //response.setHeader("Content-Length", String.valueOf(toWrite));
    response.setContentLength((int)toWrite);
    response.getOutputStream().flush();
    response.flushBuffer();
    //Files.copy(file.toPath(), response.getOutputStream());
    byte data[] = new byte[1024*1024];
    int len;
    while ((len = stream.read(data)) > 0) {
        response.getOutputStream().write(data, 0, len);
        response.getOutputStream().flush();
        response.flushBuffer();
        toWrite -= len;
        System.out.println("left="+toWrite+" "+w.getBufferSize()+" "+w.getBytes().length);
    }
    stream.close();
    response.getOutputStream().flush();
    response.getOutputStream().close();
    context.responseComplete();

对于超过1GB的文件，它以OOME结尾（这个文件大约有1.4GB）：

服务器为域修复了4GB内存，NewRatio设置为2（默认值） 如你所见，我到目前为止已尝试过：
1.玻璃鱼的更多记忆
2.更小/更大的缓冲阵列
3.每次写入后刷新响应和输出流 4.将ContentLength设置为文件大小
5.直接复制流（FileStream - ＆gt; OutputStream）
6.将Content-Length直接设置为标题
没有运气。输出应该流式化但不是。

还有什么我应该尝试的吗？

目前无法将GF升级到4，我很害怕。

最后，它按预期工作：

FacesContext context = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse) context.getExternalContext().getResponse();
ExtensionsResponseWrapper responseWrapper = (ExtensionsResponseWrapper)response;
HttpServletResponse delegateResponse = responseWrapper.getDelegate();

try {
    response.reset();
    response.setContentType("audio/vnd.wave");
    File file = new File(filename);
    long toWrite = file.length();
    filename = filename.substring(filename.lastIndexOf(File.separator) + 1, filename.length());
    response.setHeader("Content-disposition", "attachment; filename=\"" + filename + "\"");
    response.setHeader("Content-Length", String.valueOf(toWrite));
    response.setContentLength((int)toWrite);
    ServletOutputStream out = delegateResponse.getOutputStream();
    out.flush();
    response.flushBuffer();
    Files.copy(file.toPath(), out);
    response.getOutputStream().flush();
    response.getOutputStream().close();
    context.responseComplete();
} catch (IOException ex) {
    log.log(Level.SEVERE, ex.getMessage(), ex);
}

1 个答案:

答案 0 :(得分：0)

原因是类ExtensionsResponseWrapper将输出写入ByteArrayOutputStream，请参阅代码here。

我不知道这是否是标准的MyFaces响应，或者是因为您的app / GlassFish中的某些配置而使用它。查看创建/接收response对象的代码。
