Java fastdfs客户端实现上传下载文件
作者:一路繁花似锦绣前程
这篇文章主要介绍了Java fastdfs客户端实现上传下载文件,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
一、项目结构
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连接超时时间
fastdfs.connect_timeout_in_seconds=5
#tracker和storage网络通信超时时间
fastdfs.network_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(); } } }
