docker安装fastdfs与java客户端测试

一、docker 安装FastDFS

1、拉取镜像

docker pull morunchang/fastdfs

2、创建并启动tracker容器

docker run -d --name=tracker -v /home/fastdfs_docker/fdfs/tracker:/data/fast_data --privileged=true --net=host morunchang/fastdfs sh tracker.sh

 

3、创建并启动storage容器、此处只做单机版测试

     注意：由于tracker容器使用host网络模式、与宿主公用network namespace, 因此tracker容器ip与宿主机ip一致

docker run -d --name=storage -v /home/fastdfs_docker/fdfs/storage_data:/data/fast_data --privileged=rue --net=host -e TRACKER_IP=[宿主机ip]:22122 -e GROUP_NAME=group1 morunchang/fastdfs sh storage.sh

 

 

二、java客户端测试

1、创建maven测试工程

pom.xml

xml version="1.0" encoding="UTF-8"?>
<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">
    <parent>
        <artifactId>xc-framework-parentartifactId>
        <groupId>com.dehighergroupId>
        <version>1.0-SNAPSHOTversion>
        <relativePath>../xc-framework-parent/pom.xmlrelativePath>
    parent>
    <modelVersion>4.0.0modelVersion>

    <artifactId>test-fastdfsartifactId>
    <dependencies>
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>
        dependency>
        
        <dependency>
            <groupId>net.oschina.zcx7878groupId>
            <artifactId>fastdfs-client-javaartifactId>
        dependency>
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-testartifactId>
            <scope>testscope>
        dependency>
        <dependency>
            <groupId>org.apache.commonsgroupId>
            <artifactId>commons-ioartifactId>
        dependency>
    dependencies>

project>

 

 

2、在classpath:config下创建fastdfs-client.properties文件

fastdfs-client.properties

fastdfs.connect_timeout_in_seconds = 5  #http连接超时时间
fastdfs.network_timeout_in_seconds = 60 #tracker 与 storage 通信连接超时时间
fastdfs.charset = UTF-8 #字符编码
fastdfs.tracker_servers = [tracker_server_ip]:22122 #tracker_server_ip

 

3、上传文件测试

    /**
     * 上传文件
     * @throws Exception
     */
    @Test
    public void testUpload() throws Exception{
        
        ClientGlobal.initByProperties("config/fastdfs-client.properties");
        System.out.println("network_timeout=" + ClientGlobal.g_network_timeout + "ms");
        System.out.println("charset=" + ClientGlobal.g_charset);
        //创建客户端
        TrackerClient tc = new TrackerClient();
        //连接tracker Server
        TrackerServer ts = tc.getConnection();
        if (ts == null) {
        System.out.println("getConnection return null");
        return;
        } 
        //获取一个storage server
        StorageServer ss = tc.getStoreStorage(ts);
        if (ss == null) {
        System.out.println("getStoreStorage return null");
        } 
        //创建一个storage存储客户端
        StorageClient1 sc1 = new StorageClient1(ts, ss);
        NameValuePair[] meta_list = null; //new NameValuePair[0];
        String item = "C:\\Users\\degao\\Pictures\\111.png";
        String fileid;
        fileid = sc1.upload_file1(item, "png", meta_list);
        System.out.println("Upload local file " + item + " ok, fileid=" + fileid);
    }

 

 

4、查询文件信息测试

    /**
     * 查询文件
     * @throws Exception
     */
    @Test
    public void testQueryFile() throws Exception{
        ClientGlobal.initByProperties("config/fastdfs-client.properties");
        TrackerClient tracker = new TrackerClient();
        TrackerServer trackerServer = tracker.getConnection();
        StorageServer storageServer = null;
        StorageClient storageClient = new StorageClient(trackerServer,
        storageServer);
        FileInfo fileInfo = storageClient.query_file_info("group1",
                "M00/00/00/rBsAAlwM58eAcFPfAAFs5SjEXRM444.png");
        System.out.println(fileInfo);
    }

 

 

5、下载文件测试

    /**
     * 下载文件
     */
    @Test
    public void testDownloadFile() throws Exception {
    ClientGlobal.initByProperties("config/fastdfs-client.properties");
    TrackerClient tracker = new TrackerClient();
    TrackerServer trackerServer = tracker.getConnection();
    StorageServer storageServer = null;
    StorageClient1 storageClient1 = new StorageClient1(trackerServer,
    storageServer);
    byte[] result = storageClient1.download_file1("group1/M00/00/00/rBsAAlwM58eAcFPfAAFs5SjEXRM444.png");
    File file = new File("d:/1.png");
    FileOutputStream fileOutputStream = new FileOutputStream(file);
    fileOutputStream.write(result);
    fileOutputStream.close();
    }
