ps:我的文件服务器搭建在云端,每次次日访问,第一次上传就会出现这种问题,后面一整天都不会出事.后面看了下,前端是传递的数据是正常的,只是第一次访问文件服务器报异常.不知道为什么会这样,但既然第一次存储不行,那报异常的话就存储第二次吧

我的解决办法:

/**
 * 上传
 *
 * @param local_filename
 * @param file_ext_name
 * @return
 * @throws IOException
 * @throws MyException
 */
@OperLog(operType = "头像上传", operTable = "文件服务器")
public String uploadFile(byte[] local_filename, String file_ext_name) throws Exception {
    try {
        // 上传文件
        // 第一个参数可以为本地的图片路径C:\Users\Administrator\Desktop\RealWill.png,此处为图片的字节数组,第二个参数为图片的后缀png,第三个为文件的信息可以设置为null
        String[] fileInfos = null;
        try{
            fileInfos = storageClient.upload_file(local_filename, file_ext_name, null); // 这里第一次访问时fileInfos返回值为null
        }catch(Exception e){
            e.printStackTrace();
            fileInfos = storageClient.upload_file(local_filename, file_ext_name, null);
        }

        // 获取存储服务器信息
        if (fileInfos != null && fileInfos.length > 1) {
            // 第一个值是组名,第二个是相对路径;两个字符串拼接后是完整图片路径
       /* for (String fileInfo : fileInfos) {
            //group1
            //M00/00/00/rBD8vlqxsxiAdixQAABVq--SqTg455.png
            System.out.println(fileInfo);
        }*/

            // 第一个参数为追踪服务器,第二个参数为组名,第三个参数为文件相对路径
            ServerInfo[] fetchStorage = trackerClient.getFetchStorages(trackerServer, fileInfos[0], fileInfos[1]);
        /*for (ServerInfo serverInfo : fetchStorage) {
            System.out.println("ipAddr=" + serverInfo.getIpAddr()+";port=" + serverInfo.getPort());//ipAddr=120.78.169.220;port=23000
        }*/

            // 拼接完整可访问的路径;存储服务器的组对应的服务器没有组内集群的时候一般只有一个.
            // 而存储服务器上使用了nginx,使用80端口访问具体图片
            String url = "http://" + fetchStorage[0].getIpAddr() + "/" + fileInfos[0] + "/" + fileInfos[1];
            /* System.out.println(url);*/

            return url;
        }

    } catch (Exception e) {
        e.printStackTrace();
        throw new Exception("上传头像失败!原因:" + e.getMessage());
    }

    return null;
}

为了方便小白测试,我把整个方法复制了出来.最后,希望有人能告知我为什么会出现这种异常.
