1、导入坐标
<dependency>
<groupId>org.csource.fastdfs</groupId>
<artifactId>fastdfs</artifactId>
<version>1.2</version>
</dependency>
2、配置fdfs_client.conf配置文件
# connect timeout in seconds
# default value is 30s
connect_timeout=30
# network timeout in seconds
# default value is 30s
network_timeout=60
# the base path to store log files
# FastDFS安装位置
base_path=/home/fastdfs
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
# Tracker Server服务器IP地址和端口号(默认端口号:22122)
tracker_server=192.168.25.133:22122
#standard log level as syslog, case insensitive, value list:
### emerg for emergency
### alert
### crit for critical
### error
### warn for warning
### notice
### info
### debug
log_level=info
# if use connection pool
# default value is false
# since V4.05
use_connection_pool = false
# connections whose the idle time exceeds this time will be closed
# unit: second
# default value is 3600
# since V4.05
connection_pool_max_idle_time = 3600
# if load FastDFS parameters from tracker server
# since V4.05
# default value is false
load_fdfs_parameters_from_tracker=false
# if use storage ID instead of IP address
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# default value is false
# since V4.05
use_storage_id = false
# specify storage ids filename, can use relative or absolute path
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# since V4.05
storage_ids_filename = storage_ids.conf
#HTTP settings
http.tracker_server_port=80
#use "#include" directive to include HTTP other settiongs
##include http.conf
3、Java代码
package cn.itcast.test;
import org.csource.fastdfs.*;
import sun.applet.Main;
public class FastDFSTest {
public static void main(String[] args) throws Exception {
// 1、 加载配置文件
// ClientGlobal.init():fastdfs中专门用来加载配置文件
ClientGlobal.init("C:\\itcast68\\fastDFSDemo\\src\\main\\resources\\fdfs_client.conf");
// 2、 创建一个 TrackerClient 对象。 直接 new 一个。
TrackerClient client = new TrackerClient();
// 3、 使用 TrackerClient 对象创建连接, 获得一个 TrackerServer 对象。
TrackerServer server = client.getConnection();
// 4、 创建一个 StorageServer 的引用, 值为 null
StorageServer storageServer = null;
// 5、 创建一个 StorageClient 对象, 需要两个参数 TrackerServer 对象、 StorageServ
// er的引用
StorageClient storageClient = new StorageClient(server, storageServer);
// 6、 使用 StorageClient 对象上传图片。
// 参数1: 需要上传的文件的绝对路径。
// 参数2:需要上传的文件的类型(用来区分文件上传到那个StorageServer组中,实际中需要动态获取)
// 参数3:文件的详细信息
String[] strings = storageClient.upload_file("D:\\desktop\\image\\02.jpg", "jpg", null);
// 7、 返回数组。 包含组名和图片的路径。
// strings[0]:组名
// strings[1]: 路径
for (String string : strings) {
System.out.println(string);
}
}
}
2、Fast DFS工具类
1、工具类代码
package util;
import org.csource.common.NameValuePair;
import org.csource.fastdfs.ClientGlobal;
import org.csource.fastdfs.StorageClient1;
import org.csource.fastdfs.StorageServer;
import org.csource.fastdfs.TrackerClient;
import org.csource.fastdfs.TrackerServer;
public class FastDFSClient {
private TrackerClient trackerClient = null;
private TrackerServer trackerServer = null;
private StorageServer storageServer = null;
private StorageClient1 storageClient = null;
// 构造函数,创建时需要指定fdfs_client.conf配置文件的位置,与TrackerServer建立连接
public FastDFSClient(String conf) throws Exception {
if (conf.contains("classpath:")) {
conf = conf.replace("classpath:", this.getClass().getResource("/").getPath());
}
ClientGlobal.init(conf);
trackerClient = new TrackerClient();
trackerServer = trackerClient.getConnection();
storageServer = null;
storageClient = new StorageClient1(trackerServer, storageServer);
}
/**
* 上传文件方法
* <p>Title: uploadFile</p>
* <p>Description: </p>
* @param fileName 文件全路径
* @param extName 文件扩展名,不包含(.)
* @param metas 文件扩展信息
* @return
* @throws Exception
*/
public String uploadFile(String fileName, String extName, NameValuePair[] metas) throws Exception {
String result = storageClient.upload_file1(fileName, extName, metas);
return result;
}
public String uploadFile(String fileName) throws Exception {
return uploadFile(fileName, null, null);
}
public String uploadFile(String fileName, String extName) throws Exception {
return uploadFile(fileName, extName, null);
}
/**
* 上传文件方法
* <p>Title: uploadFile</p>
* <p>Description: </p>
* @param fileContent 文件的内容,字节数组
* @param extName 文件扩展名
* @param metas 文件扩展信息
* @return
* @throws Exception
*/
public String uploadFile(byte[] fileContent, String extName, NameValuePair[] metas) throws Exception {
String result = storageClient.upload_file1(fileContent, extName, metas);
return result;
}
public String uploadFile(byte[] fileContent) throws Exception {
return uploadFile(fileContent, null, null);
}
public String uploadFile(byte[] fileContent, String extName) throws Exception {
return uploadFile(fileContent, extName, null);
}
}
2、实现文件上传
applaction.properties配置文件
# TrackerServer服务器IP地址
FILE_SERVER_URL=http://192.168.25.133/
java代码
package com.pinyougou.shop.controller;
import com.pinyougou.sellergoods.service.GoodsDescService;
import entity.Result;
import jdk.nashorn.internal.ir.annotations.Reference;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import util.FastDFSClient;
/**
* @author Hxc@hongxiancheng.com
* @date 2018/11/24 11:04
*/
@RestController
@RequestMapping("/fastDFS")
public class UploadController {
@Value("${FILE_SERVER_URL}")
private String file_url; // TrackerServer服务器IP地址
// 文件上传
@RequestMapping("/upload")
public Result upload(MultipartFile file) {
try {
// 获取文件名称
String fileName = file.getOriginalFilename();
// 获取文件类型
String type = fileName.substring(fileName.lastIndexOf(".") + 1);
// 获取FasdDFS工具类对象
FastDFSClient fastDFSClient = new FastDFSClient("classpath:config/fdfs_client.conf");
// 上传文件,返回file_id
// 参数1:需要上传的文件,使用二进制形式(网络传输)
// 参数2:文件类型,扩展名
String fileId = fastDFSClient.uploadFile(file.getBytes(), type);// 上传文件
// 返回trackerServer服务器IP地址和file_id,或者保存到本地数据库
return new Result(true, FILE_SERVER_URL + fileId);
} catch (Exception e) {
e.printStackTrace();
return new Result(false, "上传失败");
}
}
}
