fastdfs-client-java操作fastdfs

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38

< 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" >    < modelVersion >4.0.0</ modelVersion >      < groupId >com.leech</ groupId >    < artifactId >fastdfs-demo</ artifactId >    < version >0.0.1-SNAPSHOT</ version >    < packaging >jar</ packaging >      < name >fastdfs-demo</ name >    < url >http://maven.apache.org</ url >      < properties >      < project.build.sourceEncoding >UTF-8</ project.build.sourceEncoding >    </ properties >      < dependencies >      < dependency >        < groupId >junit</ groupId >        < artifactId >junit</ artifactId >        < version >4.11</ version >        < scope >test</ scope >      </ dependency >            < dependency >        < groupId >org.csource</ groupId >        < artifactId >fastdfs-client-java</ artifactId >        < version >5.0.4</ version >      </ dependency >            < dependency >          < groupId >commons-io</ groupId >          < artifactId >commons-io</ artifactId >          < version >2.4</ version >      </ dependency >          </ dependencies > </ project >

 

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

执行testUpload方法如下
