fastdfs-client-java操作fastdfs5.0.5

上一篇我们安装好了环境，这一次我们使用Java进行文件操作

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">
  <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 #没什么屌用
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
