springboot2.0結合fastdfs實現文件分佈式上傳

1. 引入依賴

在父工程中，咱們已經管理了依賴，版本爲：

<fastDFS.client.version>1.26.7</fastDFS.client.version>

所以，這裏咱們直接在工程的pom.xml中引入座標便可：

<dependency>
    <groupId>com.github.tobato</groupId>
    <artifactId>fastdfs-client</artifactId>
</dependency>

@Configuration
@Import(FdfsClientConfig.class)
// 解決jmx重複註冊bean的問題
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
public class FastClientImporter {
    
}

2. 在application.yml文件中編寫FastDFS屬性

fdfs:
  so-timeout: 1501 # 超時時間
  connect-timeout: 601 # 鏈接超時時間
  thumb-image: # 縮略圖
    width: 60
    height: 60
  tracker-list: # tracker地址：你的虛擬機服務器地址+端口（默認是22122）
    - 192.168.0.22:22122

3. 測試

package com.leyou.upload.test;

import com.github.tobato.fastdfs.domain.fdfs.StorePath;
import com.github.tobato.fastdfs.domain.fdfs.ThumbImageConfig;
import com.github.tobato.fastdfs.service.FastFileStorageClient;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
