Javafastdfs客户端实现上传下载文件

Javafastdfs客户端实现上传下载⽂件⼀、项⽬结构

⼆、pom.xml

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="/POM/4.0.0"

xmlns:xsi="/2001/XMLSchema-instance"

xsi:schemaLocation="/POM/4.0.0 /xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

<groupId>org.example</groupId>

<artifactId>A01fastdfs</artifactId>

</dependency>

<!-- https:///artifact/mons/commons-io -->

<dependency>

<groupId>mons</groupId>

<artifactId>commons-io</artifactId>

</dependencies>

<build>

<plugins>

<plugin>

<configuration>

<target>1.9</target>

</configuration>

</plugin>

</plugins>

</build>

</project>

三、fastdfs-client.properties

#http连接超时时间

fastdfs.connect_timeout_in_seconds=5

#tracker和storage⽹络通信超时时间

work_timeout_in_seconds=30

#字符编码

fastdfs.charset=utf-8

#tracker服务器地址，多个地址中间⽤英⽂逗号分隔

fastdfs.tracker_servers=192.168.2.105:22122

四、测试

package com.wuxi.test;

import org.csource.fastdfs.*;

import org.junit.Test;

import java.io.File;

import java.io.FileOutputStream;

public class MyTest {

//上传⽂件

@Test

public void testUpload() {

try {

//加载fastdfs-client.properties配置⽂件

ClientGlobal.initByProperties("config/fastdfs-client.properties");

//定义TrackerClient，⽤于请求TrackerServer

TrackerClient trackerClient = new TrackerClient();

//连接tracker

TrackerServer trackerServer = trackerClient.getConnection();

//获取storage

StorageServer storeStorage = trackerClient.getStoreStorage(trackerServer);

//创建storageClient

StorageClient1 storageClient1 = new StorageClient1(trackerServer, storeStorage);

//向storage服务器上传⽂件

//本地⽂件的路径

String path = "F:/java/resource/data.txt";

//上传成功后拿到⽂件Id

String fileId = storageClient1.upload_file1(path, "txt", null);

System.out.println(fileId);//group1/M00/00/00/wKgCaV9vaSaARBTKAAAAGjJpL2g017.txt

} catch (Exception e) {

e.printStackTrace();

}

}

//下载⽂件

@Test

public void testDownload() {

try {

//加载fastdfs-client.properties配置⽂件

ClientGlobal.initByProperties("config/fastdfs-client.properties");

//定义TrackerClient，⽤于请求TrackerServer

TrackerClient trackerClient = new TrackerClient();

//连接tracker

TrackerServer trackerServer = trackerClient.getConnection();

//获取storage

StorageServer storeStorage = trackerClient.getStoreStorage(trackerServer);

//创建storageClient

StorageClient1 storageClient1 = new StorageClient1(trackerServer, storeStorage);

//下载⽂件

//⽂件id

String fileId = "group1/M00/00/00/wKgCaV9vaSaARBTKAAAAGjJpL2g017.txt";

byte[] bytes = storageClient1.download_file1(fileId);

//使⽤输出流保存⽂件

FileOutputStream fileOutputStream = new FileOutputStream(new File("F:/data.txt"));

fileOutputStream.write(bytes);

} catch (Exception e) {

e.printStackTrace();

}

}

}
