一、項目結構

二、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'> <modelVersion>4.0.0</modelVersion> <groupId>org.example</groupId> <artifactId>A01fastdfs</artifactId> <version>1.0-SNAPSHOT</version> <dependencies> <!-- https://mvnrepository.com/artifact/net.oschina.zcx7878/fastdfs-client-java --> <dependency> <groupId>net.oschina.zcx7878</groupId> <artifactId>fastdfs-client-java</artifactId> <version>1.27.0.0</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.13</version> <scope>test</scope> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.commons/commons-io --> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-io</artifactId> <version>1.3.2</version> </dependency> </dependencies> <build> <plugins> <plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><configuration> <source>1.9</source> <target>1.9</target></configuration> </plugin> </plugins> </build></project>

三、fastdfs-client.properties

#http連接超時時間fastdfs.connect_timeout_in_seconds=5#tracker和storage網絡通信超時時間fastdfs.network_timeout_in_seconds=30#字符編碼fastdfs.charset=utf-8#tracker服務器地址，多個地址中間用英文逗號分隔fastdfs.tracker_servers=192.168.2.105:22122

四、測試

package com.wuxi.test;import org.csource.fastdfs.*;import org.junit.Test;import java.io.File;import java.io.FileOutputStream;public class MyTest { //上傳文件 @Test public void testUpload() { try { //加載fastdfs-client.properties配置文件 ClientGlobal.initByProperties('config/fastdfs-client.properties'); //定義TrackerClient，用于請求TrackerServer TrackerClient trackerClient = new TrackerClient(); //連接tracker TrackerServer trackerServer = trackerClient.getConnection(); //獲取storage StorageServer storeStorage = trackerClient.getStoreStorage(trackerServer); //創建storageClient StorageClient1 storageClient1 = new StorageClient1(trackerServer, storeStorage); //向storage服務器上傳文件 //本地文件的路徑 String path = 'F:/java/resource/data.txt'; //上傳成功后拿到文件Id String fileId = storageClient1.upload_file1(path, 'txt', null); System.out.println(fileId);//group1/M00/00/00/wKgCaV9vaSaARBTKAAAAGjJpL2g017.txt } catch (Exception e) { e.printStackTrace(); } } //下載文件 @Test public void testDownload() { try { //加載fastdfs-client.properties配置文件 ClientGlobal.initByProperties('config/fastdfs-client.properties'); //定義TrackerClient，用于請求TrackerServer TrackerClient trackerClient = new TrackerClient(); //連接tracker TrackerServer trackerServer = trackerClient.getConnection(); //獲取storage StorageServer storeStorage = trackerClient.getStoreStorage(trackerServer); //創建storageClient StorageClient1 storageClient1 = new StorageClient1(trackerServer, storeStorage); //下載文件 //文件id String fileId = 'group1/M00/00/00/wKgCaV9vaSaARBTKAAAAGjJpL2g017.txt'; byte[] bytes = storageClient1.download_file1(fileId); //使用輸出流保存文件 FileOutputStream fileOutputStream = new FileOutputStream(new File('F:/data.txt')); fileOutputStream.write(bytes); } catch (Exception e) { e.printStackTrace(); } }}
