求各位大佬帮帮忙，帮我解决这个bug
把代码贴出来看看，异常也得根据代码来发现问题。

使用debug判断哪一行出现错误，然后贴出出错地方的整块代码
1、看看你的网络怎么样
2、看看你上传的文件怎么样
3、如果你web服务器是用nginx的话，看看nginx配置里面的上传包大小限制项
4、最后还是有问题的话请贴代码
图片上传的代码 用的是nginx代理服务器
public String uploadImage(MultipartFile uploadFile){
String oldName = uploadFile.getOriginalFilename();
String extName = oldName.substring(oldName.lastIndexOf(".")+1);//图片后缀名
Map hashmap = new HashMap();
try {
String url = client.uploadFile(uploadFile.getBytes(),extName);
hashmap.put("error", 0);
hashmap.put("url",IMAGE_URL+url);
return JsonUtils.objectToJson(hashmap);
} catch (Exception e) {
// TODO: handle exception
hashmap.put("error", 1);
hashmap.put("message", "图片上传失败");
e.printStackTrace();
return JsonUtils.objectToJson(hashmap);
}
}
