解决方法：server 端使用 V6.11，fastdfs-clint-java需要使用最新的 V1.31。进入官网fastdfs-client-java-1.31下载最新的程序，然后安装至本地maven仓库
安装方法：

1. 指定一个路径解压下载的zip压缩包
2. 进入解压后的fastdfs-client-java-1.31文件夹，并在此路径打开cmd命令行窗口，随后执行

mvn clean install

3. 显示build success表明已经安装成功
4. 在maven项目pom.xml中添加依赖

<dependency>
    <groupId>org.csource</groupId>
    <artifactId>fastdfs-client-java</artifactId>
    <version>1.31-SNAPSHOT</version>
