ios代码：
-(void)sendImg:img:(UIImage *)image{
//请求地址
NSMutableString *url = [[NSMutableString alloc] init];
[url appendString:[UtilTool getHostURL]];
[url appendString:@"savePic"];
NSString *TWITTERFON_FORM_BOUNDARY = @"AaB03x";
//分界线 --AaB03x
NSString *MPboundary=[[NSString alloc]initWithFormat:@"--%@",TWITTERFON_FORM_BOUNDARY];
//结束符 AaB03x--
NSString *endMPboundary=[[NSString alloc]initWithFormat:@"%@--",MPboundary];
NSMutableString *body = [[NSMutableString alloc] init];
[body appendFormat:@"%@\r\n",MPboundary];
//请求参数
[body appendFormat:@"Content-Disposition: form-data;name=\"%@\"\r\n\r\n",@"token"];
//参数值
[body appendFormat:@"%@\r\n", [UtilTool getToken]];
NSData *imageData = UIImagePNGRepresentation([UtilTool changeImg:image max:1136]);
//声明myRequestData，用来放入http body
NSMutableData *myRequestData;
//将body字符串转化为UTF8格式的二进制
myRequestData=[NSMutableData data];
//上传文件
[body appendFormat:@"%@\r\n",MPboundary];
[body appendFormat:@"Content-Disposition: form-data; name=\"uploadFile\"; filename=\"%@\"\r\n",@"temp.png"];
[body appendFormat:@"Content-Type: image/png\r\n\r\n"];
[myRequestData appendData:[body dataUsingEncoding:NSUTF8StringEncoding]];
[myRequestData appendData:imageData];
//声明结束符：--AaB03x--
NSString *end=[[NSString alloc]initWithFormat:@"\r\n%@",endMPboundary];
//加入结束符--AaB03x--
[myRequestData appendData:[end dataUsingEncoding:NSUTF8StringEncoding]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:url]];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
// [request setTimeoutInterval:[DataStore getHttpTimeout]];
[request setHTTPMethod:@"POST"];
//设置HTTPHeader中Content-Type的值
NSString *cttype=[[NSString alloc]initWithFormat:@"multipart/form-data; boundary=%@",TWITTERFON_FORM_BOUNDARY];
//设置HTTPHeader
[request setValue:cttype forHTTPHeaderField:@"Content-Type"];
//设置Content-Length
[request setValue:[NSString stringWithFormat:@"%ld", [myRequestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:myRequestData];
[NSURLConnection sendSynchronousRequest:request returningResponse:nil error: nil];
}
后台代码：
@RequestMapping(value = {"/savePic"}, method = RequestMethod.POST, produces= { "application/json" })
@ResponseBody
public String savePic(MultipartFile uploadFile, HttpServletRequest request) throws IOException, JSONException{

if(uploadFile != null){ //上传文件

//修改文件名字，格式取当前时间
toFile = new File(path, DateVaildator.simpleDateFormat(new Date(), "yyyyMMddHHmmss") + fileType);
targetFile.renameTo(toFile);
if (!toFile.exists()) {
toFile.mkdirs();
}
//保存至我们服务器
uploadFile.transferTo(toFile);
