java http post上传文件

1.上传接口

@IgnoreToken

 @RequestMapping(value = "/upload/cpicFile", method = RequestMethod.POST)

 public void cpicFile(HttpServletResponse response, HttpServletRequest request){

 ErrorCode errorCode = ErrorCode.FAILED;

 Map<String,Object> reqData = this.getContent(request);

 String path = SysConf.CPIC_WORKBASEDIR; //上传路径

 try {

 String name = (String)reqData.get("name");

 String content = (String)reqData.get("content");

 byte[] bytes = org.apache.commons.codec.binary.Base64.decodeBase64(content);

 //写入文件

 File fileTmp = new File(path + name); //临时文件

 FileOutputStream fop = new FileOutputStream(fileTmp);

 if (!fileTmp.exists()) {

 fileTmp.createNewFile();

 }

 fop.write(bytes);

 fop.flush();

 fop.close();

 System.err.println("Done");

 errorCode = ErrorCode.SUCCESS;

 } catch (Exception e){

 logger.error("上传CPIC图片异常",e);

 errorCode = ErrorCode.SYS_ERROR;

 }

 sendResponseContent(response, reqData, errorCode);

 }

2.测试接口

@Test

 public void testCpicUploadFile(){

 try {

 Map<String,Object> paramMap=new HashMap<>();

 paramMap.put("name", "cpic-160714.xml");

 File f = new File("C:/sftp/cpic-20160713-3.xml");

 InputStream in = new FileInputStream(f);

 byte[] b = new byte[(int)f.length()]; //创建合适文件大小的数组

 in.read(b); //读取文件中的内容到b[]数组

 in.close();

 String s = new String(b);

 System.out.println("s = " + s);

 System.out.println("b1 = " + b); //内存地址

 String ss = org.apache.commons.codec.binary.Base64.encodeBase64String(b); //base64编码

 System.out.println("ss = " + ss);

 System.out.println("b2 = " + Base64.decodeBase64(ss)); //内存地址

 paramMap.put("content", ss);

 //@IgnoreToken

// paramMap.put("token", "54ungzbaach65xypcceq48gd6jwlyros"); //token可以加一个注解。

 System.out.println("paramMap="+paramMap);

 HttpResult httpResult = HttpUtil.post("/cpic/upload/cpicFile",paramMap);

 System.out.println(httpResult);

 } catch (Exception e) {

 e.printStackTrace();

 } 

 }
