注意点：

//构造一个带指定Zone对象的配置类 Configuration cfg = new Configuration(Zone.zone0());//Zone.zone0() 指华东 Configuration cfg = new Configuration(Zone.zone1());//华北 Configuration cfg = new Configuration(Zone.zone2());//华南

上传本地文件并且生成外链：

private String path = "C:\\Users\\ASUS\\Desktop\\课表.jpg";    @Test    public void haha() {
           //构造一个带指定 Region 对象的配置类        Configuration cfg = new Configuration(Region.region2());//...其他参数参考类注释        UploadManager uploadManager = new UploadManager(cfg);//...生成上传凭证，然后准备上传        String accessKey = "yours key";        String secretKey = "yours key";        String bucket = "ywf";//默认不指定key的情况下，以文件内容的hash值作为文件名        String key = null;        try {
                          Auth auth = Auth.create(accessKey, secretKey);            String upToken = auth.uploadToken(bucket);            try {
                   Response response = uploadManager.put(path, key, upToken);                //解析上传成功的结果                DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);                System.out.println(putRet.key);                System.out.println(putRet.hash);            } catch (QiniuException ex) {

图片服务器 会给你一个域名，将 域名+ ret.hash

@Override    public String saveImageWithPath(MultipartFile file) {
           if(!checkSize(file)) {
               return "ERROR";        }        Configuration cfg = new Configuration(Region.region0());//华东的仓库//...其他参数参考类注释        UploadManager uploadManager = new UploadManager(cfg);        String key = null;        Auth auth = Auth.create(accessKey, secretKey);        String upToken = auth.uploadToken(buckName);        String result=null;        try {
               Response response = uploadManager.put(file.getBytes(), key, upToken);            //解析上传成功的结果            DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);            // System.out.println(putRet.key);            // System.out.println(putRet.hash);            log.info(putRet.key);            result = putRet.hash;        } catch (QiniuException ex) {
               Response r = ex.response;            log.error(r.toString());            try {
                   log.error(r.bodyString());            } catch (QiniuException ex2) {
                   //ignore                log.error(String.valueOf(ex2));            }        } catch (IOException e) {
               log.error(e.getMessage());        }        //图片路径： 域名+'/'+ 具体的hash值        return prefix+'/'+result;    }
