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
