fastdfs-client-java操做fastdfs5.0.4

1、在https://github.com/happyfish100/fastdfs-client-java 下載客戶端，解壓後並執行ant命令，在E:\tools\libs\fastdfs\fastdfs-client-java-master\src\build下會生成fastdfs_client.jar如圖示

2、mvn安裝fastdfs_client.jar，在cmd中執行命令

mvn install:install-file -DgroupId=org.csource -DartifactId=fastdfs-client-java -Dversion=5.0.4 -Dpackaging=jar -Dfile=D:\fastdfs_client.jar 

3、在eclipse中新建maven項目fastdfs-demo，在pom.xml中加入依賴以下

<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">

	</dependency>
    
  </dependencies>
</project>

在src/main/resources中新建fdfs_client.conf文件，內容以下

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中建立TestFastDfs.java以下
