fastdfs-client-java操作fastdfs5.0.4

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

< project  xmlns = "http://maven.apache.org/POM/4.0.0"  xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation = "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" >

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
