HttpClient 通过Post 上传文件。

public class UploadService {/** * 默认的URL */private static final String DEFAULT_HTTP_POST_URL = "http://localhost:8090/uploadfile";private Logger logger = LoggerFactory.getLogger(UploadService.class);private String url = DEFAULT_HTTP_POST_URL;@Autowiredprivate HttpProvider httpProvider;/** *  * 初始化参数信息 */@PostConstructpublic void initConfig() {url = Configuration.getInstance().getValue("url");}/** *  * 上传文件到汇总统计程序 * @param filePath * @throws IOException */public void uploadFile(String filePath) throws IOException {HttpClient client = httpProvider.getHttpClient();client.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);HttpPost post = new HttpPost(url);File file = new File(filePath);MultipartEntity mpEntity = new MultipartEntity();ContentBody cbFile = new FileBody(file);mpEntity.addPart("file", cbFile);post.setEntity(mpEntity);HttpResponse response = client.execute(post);String content = EntityUtils.toString(response.getEntity());logger.debug("filePath :{} ,content :{}", filePath, content);client.getConnectionManager().shutdown();}

带源地址的Httpclient
