Docker 搭建FastDFS+SpringBoot整合FastDFS

环境搭建

1. 搭建 Tracker

docker run -d --network=host --name tracker -v /var/fdfs/tracker:/var/fdfs delron/fastdfs tracker

2. 搭建 Storage （注意修改TRACKER_SERVER IP）

docker run -d --network=host --name storage -e TRACKER_SERVER=192.168.0.102:22122 -v /var/fdfs/storage:/var/fdfs -e GROUP_NAME=group1 delron/fastdfs storage

3. 配置修改 进入Stroage 容器 /etc/fdfs/storage.conf 把 http.server_port=8888改为任意端口（我这里使用80端口）
4. 修改nginx配置 路径/usr/local/nginx/conf nginx.conf 改为和server_port端口一样 然后保存重启容器

server {
        listen       80;
        server_name  localhost;
        location ~/group[0-9]/ {
            ngx_fastdfs_module;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root html;
        }
    }

5. 测试：往宿主机/var/fdfs/storage/a.jpg 放一张照片 然后进入stroage 容器/var/fdfs/storage/目录下，运行下面命令 生成图片路径(访问，检查是否放开80端口)

/usr/bin/fdfs_upload_file /etc/fdfs/client.conf a.jpg

Spring Boot整个FastDFS

1. 引入依赖

  
         <dependency>
            <groupId>com.github.tobatogroupId>
            <artifactId>fastdfs-clientartifactId>
            <version>1.26.5version>
        dependency>

2. 添加配置信息（请检查端口是否开放）

fdfs:
  soTimeout: 15000 #socket连接超时时长
  connectTimeout: 15000 #连接tracker服务器超时时长
  reqHost: 192.168.0.102   #nginx访问地址
  reqPort: 80              #nginx访问端口
  thumbImage: #缩略图生成参数，可选
    width: 150
    height: 150
  trackerList: #TrackerList参数,支持多个，我这里只有一个，如果有多个在下方加- x.x.x.x:port
    - 192.168.0.102:22122

3. 创建FastDFS客户端配置类

package com.pig4cloud.pig.client.util;

import com.github.tobato.fastdfs.domain.fdfs.StorePath;
import com.github.tobato.fastdfs.domain.fdfs.ThumbImageConfig;
import com.github.tobato.fastdfs.domain.proto.storage.DownloadCallback;
import com.github.tobato.fastdfs.service.FastFileStorageClient;
import org.apache.commons.io.FilenameUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;

import java.io.IOException;
import java.io.InputStream;
 
 
@Component
public class FastDFSClientUtil {
 
	@Value("${fdfs.reqHost}")
    private String reqHost;
 
    @Value("${fdfs.reqPort}")
    private String reqPort;
	
    @Autowired
    private FastFileStorageClient storageClient;
    
    @Autowired
    private ThumbImageConfig thumbImageConfig; //创建缩略图   ， 缩略图访问有问题，暂未解决
 
     
   public String uploadFile(MultipartFile file) throws IOException {
       StorePath storePath = storageClient.uploadFile((InputStream)file.getInputStream(),file.getSize(), FilenameUtils.getExtension(file.getOriginalFilename()),null);
       
       String path = thumbImageConfig.getThumbImagePath(storePath.getPath()) ;
       System.out.println("thumbImage :" + path);  //   缩略图访问有问题，暂未解决
       
       return getResAccessUrl(storePath);
   }
 
   public void delFile(String filePath) { 
	   storageClient.deleteFile(filePath);
	   
   }
 
   
   public InputStream download(String groupName, String path ) {
	   InputStream ins =  storageClient.downloadFile(groupName, path, new DownloadCallback<InputStream>(){
		@Override
		public InputStream recv(InputStream ins) throws IOException {
			// 将此ins返回给上面的ins 
			return ins;
		}}) ;
	   return ins ;
   }
   
    /**
      * 封装文件完整URL地址
     * @param storePath
     * @return
     */
   private String getResAccessUrl(StorePath storePath) {
       String fileUrl = "http://" + reqHost + ":" + reqPort + "/" + storePath.getFullPath();
       return fileUrl;
   }
}

4. 在启动类上面导入配置注解

@Import(FdfsClientConfig.class) // 导入FastDFS-Client组件

5. 创建Controller代码

package com.pig4cloud.pig.client.controller.common;

import com.google.common.collect.Maps;
import com.pig4cloud.pig.client.util.FastDFSClientUtil;
import com.pig4cloud.pig.common.core.util.R;
import com.pig4cloud.pig.common.security.annotation.Inner;
import org.apache.commons.io.IOUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;

@RestController
    @RequestMapping("/common")
@Inner(value = false)
public class UploadController {

    @Autowired
    private FastDFSClientUtil dfsClient;


    @PostMapping("/upload")
    public R<?> fdfsUpload(@RequestParam("file") MultipartFile file, HttpServletRequest request) {
        try {
            HashMap<String, String> objectObjectHashMap = Maps.newHashMap();
            String fileUrl = dfsClient.uploadFile(file);
            objectObjectHashMap.put("url", fileUrl);
            return R.ok(objectObjectHashMap);

        } catch (IOException e) {
            e.printStackTrace();
            return R.failed("上传异常");
        }
    }


    @RequestMapping("/download")
    public void download(String filePath, HttpServletRequest request, HttpServletResponse response) throws IOException {
        String[] paths = filePath.split("/");
        String groupName = null;
        for (String item : paths) {
            if (item.indexOf("group") != -1) {
                groupName = item;
                break;
            }
        }
        String path = filePath.substring(filePath.indexOf(groupName) + groupName.length() + 1, filePath.length());
        InputStream input = dfsClient.download(groupName, path);

        //根据文件名获取 MIME 类型
        String fileName = paths[paths.length - 1];
        System.out.println("fileName :" + fileName); // wKgIZVzZEF2ATP08ABC9j8AnNSs744.jpg
        String contentType = request.getServletContext().getMimeType(fileName);
        String contentDisposition = "attachment;filename=" + fileName;

        // 设置头
        response.setHeader("Content-Type", contentType);
        response.setHeader("Content-Disposition", contentDisposition);

        // 获取绑定了客户端的流
        ServletOutputStream output = response.getOutputStream();

        // 把输入流中的数据写入到输出流中
        IOUtils.copy(input, output);
        input.close();

    }

    /**
     * @param fileName group1/M00/00/00/wKgIZVzZaRiAZemtAARpYjHP9j4930.jpg
     * @param request
     * @param response
     * @return
     */
    @RequestMapping("/deleteFile")
    public R<?> delFile(String filePath, HttpServletRequest request, HttpServletResponse response) {
        try {
            dfsClient.delFile(filePath);
            return R.ok("删除成功");
        } catch (Exception e) {
            return R.failed("删除异常");
        }
    }


}
