引用fastdfs图片服务器

1. 引入jar包

<dependency>
            <groupId>net.arccode</groupId>
            <artifactId>fastdfs-client-java</artifactId>
            <version>1.27.0</version>

常见错误分析

fastdfs上传报错 recv package size -1 != 10

这错误一般是上传出错但是第二次上传又是正常的一般在反复调用时候出现

文中一个类出现两次就是为了屏蔽该类错误

fastDFSClient = new FastDFSClient(fastdfs.getServiceUrl());

java.net.SocktetException: Broken pipe(write failed)

这是因为图片服务器连接不上建议检查fastdfs与fastdfs服务器之间连接通道
