Question

我收回了同事的节目。

他做了这个方法（这个程序允许在服务器上传文件）：

protected String uploadFile(File inputFile, String uuidFile) throws IOException,
        ClientProtocolException {
    HttpPost post = new HttpPost(new StringBuilder()
            .append("http://xxxxxxxxxxxxx/FileServlet/").append("/uploadFile")
            .toString());
    post.addHeader("UuidFile", uuidFile);

    MultipartEntityBuilder builder = MultipartEntityBuilder.create();
    builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
    builder.addPart("file", new FileBody(inputFile));
    HttpEntity httpEntity = builder.build();

    post.setEntity(httpEntity);

    CloseableHttpClient client = HttpClients.createDefault();
    HttpResponse response = null;
    try {
        response = client.execute(post);

        if (response.getStatusLine().getStatusCode() == 200) {
            Pattern p = Pattern.compile("File uploaded into (.*)</h2>");
            String messageErreur = IOUtils.toString(response.getEntity().getContent());
            System.out.println(messageErreur);
            Matcher m = p.matcher(messageErreur);
            if (m.find()) {
                return m.group(1);
            }
        } else {
            throw new RuntimeException(response.getStatusLine().getStatusCode() + ": " + new String(IOUtils.toByteArray(response.getEntity().getContent())));
        }
        return null;
    } finally {
        client.close();
    }
}

控制台中的错误是

出现错误：请求因其大小而被拒绝（68142301）超出配置的最大值（52428800）

但是我不知道如何增加上传文件的最大大小......

你有什么想法吗？

谢谢，阿诺

Answer 1

从现在开始解决错误检查web.xml以获取servlet中的以下配置。增加尺寸并检查。

 <multipart-config>   
    <max-file-size>68142301</max-file-size>
    <max-request-size>68142301</max-request-size>
    <file-size-threshold>0</file-size-threshold>
    </multipart-config>

Answer 2

它的功能，另一位同事给了项目方服务，它有

ServletFileUpload upload = new ServletFileUpload(factory);

        // sets maximum size of upload file
        upload.setFileSizeMax(MAX_FILE_SIZE);

        // sets maximum size of request (include file + form data)
        upload.setSizeMax(MAX_REQUEST_SIZE);

改变
