下载fastdfs-client-java源码添加到项目工程里面，添加配置文件：fdfs_client.conf
这个jar包在中央仓库是没有的，我们可以将源码下载下来，使用maven install安装到本地仓库。
一、在https://github.com/happyfish100/fastdfs-client-java 下载客户端，解压后并执行ant命令，在E:\tools\libs\fastdfs\fastdfs-client-java-master\src\build下会生成fastdfs_client.jar如图示
二、mvn安装fastdfs_client.jar，在cmd中执行命令
mvn install:install-file -DgroupId=org.csource -DartifactId=fastdfs-client-java -Dversion=5.0.4 -Dpackaging=jar -Dfile=D:\fastdfs_client.jar
三、在eclipse中新建maven项目fastdfs-demo，在pom.xml中加入依赖如下

在src/main/resources中新建fdfs_client.conf文件，内容如下
connect_timeout = 2
network_timeout = 30
charset = UTF-8
http.tracker_http_port = 80
http.anti_steal_token = no
http.secret_key = FastDFS1234567890
tracker_server = 192.168.17.112:22122
#tracker_server = 192.168.0.119:22122
在src/main/java中创建TestFastDfs.java如下
