這里直接貼出的是我封裝好的doPostFile方法,httpclient 的版本是3.1。

public static String doPostFile(String url, Part[] parts){String response = null;PostMethod postMethod = new PostMethod(url);try{ //設置請求實體postMethod.setRequestEntity(new MultipartRequestEntity(parts,postMethod.getParams()));HttpClient client = new HttpClient();//設置連接超時限度client.getHttpConnectionManager().getParams().setConnectionTimeout(5000);client.executeMethod(postMethod);if(postMethod.getStatusCode() == HttpStatus.SC_OK){response = new String(postMethod.getResponseBodyAsString().getBytes("utf-8"));}} catch(Exception e){LOGGER.error("HttpServiceSender.doPostFile()",e.getMessage());} finally {postMethod.releaseConnection();}return response;}

調用此方法的代碼，注意參數(shù)的傳遞方式

public String uploadImage(File file,String id,String name){String result = null;try{ //文件part,new FilePart添加的是File類型的文件，后面StringPart則為字符串參數(shù)Part[] parts = { new FilePart("file", file),new StringPart("id", id), new StringPart("id",name)};result = HttpServiceSender.doPostFile(SERVER+"service/resource/upload",parts);}catch(Exception e){Logger.error("ImageService.uploadImage()", e.getMessage()); } return result;}
