接上一篇，[docker搭建FastDFS文件系统。][docker_FastDFS]

这一篇实现SpringBoot2.0整合Fastdfs。

1.引入FastDfs依赖

<dependency>
       <groupId>com.github.tobato</groupId>
       <artifactId>fastdfs-client</artifactId>
       <version>1.26.2</version>
    </dependency>

2.application.yml配置文件

fdfs:
      connect-timeout: 600
      so-timeout: 1500
      trackerList: 127.0.0.1:22122 
      thumb-image:  
        width: 150
        height: 150
      pool:
        max-total: 200

3.在启动类添加如下配置

@Configuration
    @SpringBootApplication
    @MapperScan("com.gbq.boot.web.mapper")
    @EnableMBeanExport(registration= RegistrationPolicy.IGNORE_EXISTING)
    @Import(FdfsClientConfig.class)
    @EnableAsync
    public class BootApplication {
        public static void main(String[] args) {
            SpringApplication.run(BootApplication.class, args);
        }
    }

4.controller 接口编写

package com.gbq.boot.web.controller;
    
    
    import com.github.tobato.fastdfs.domain.StorePath;
    import com.github.tobato.fastdfs.proto.storage.DownloadByteArray;
    import com.github.tobato.fastdfs.service.FastFileStorageClient;
    import org.apache.velocity.shaded.commons.io.FilenameUtils;
    import org.springframework.web.bind.annotation.*;
    import org.springframework.web.multipart.MultipartFile;
    
    import javax.annotation.Resource;
    import javax.servlet.ServletOutputStream;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    import java.net.URLEncoder;
    import java.util.HashMap;
    
    @RestController
    @RequestMapping("/file")
    public class FileController {
    
        @Resource
        private FastFileStorageClient fastFileStorageClient;
    
        /**
         * 文件上传
         * @return result
         */
        @ResponseBody
        @PostMapping("/upload")
        public HashMap<String, Object> uploadImageByCover(MultipartFile attach){
            HashMap<String,Object> result = new HashMap<>();
            try {
                //上传
                StorePath path = fastFileStorageClient.
                                uploadFile(attach.getInputStream(),attach.getSize(),
                                FilenameUtils.getExtension(attach.getOriginalFilename()),null);
                //获取路径加名称
                String picName = path.getFullPath();
                result.put("msg",picName);
            } catch (IOException e) {
                e.printStackTrace();
            }
            return result;
        }
    
        /**
         * 文件删除
         * @param path
         * @return
         */
        @DeleteMapping("/delete")
        public HashMap<String, Object> delete(@RequestParam String path) {
            HashMap<String,Object> result = new HashMap<>();
            // 第一种删除：参数：完整地址
            fastFileStorageClient.deleteFile(path);
            result.put("msg","恭喜恭喜，删除成功！");
            // 第二种删除：参数：组名加文件路径
            // fastFileStorageClient.deleteFile(group,path);
    
            return result;
        }
    
    
      /**
         * 文件下载
         * @param url 路径
         * @return
         */
        @GetMapping("/download")
        public void downLoad(@RequestParam String url, HttpServletResponse response) throws IOException {
            String group = url.substring(0, url.indexOf("/"));
            String path = url.substring(url.indexOf("/") + 1);
            //文件后缀
            String substring = url.substring(url.lastIndexOf(".") + 1);
            byte[] bytes = fastFileStorageClient.downloadFile(group, path, new DownloadByteArray());
    
            response.setCharacterEncoding("UTF-8");
            response.setHeader("Content-disposition", "attachment;filename=" + URLEncoder.encode(UUID.randomUUID().toString()+"."+substring, "UTF-8"));
    
            // 写出
            ServletOutputStream outputStream = response.getOutputStream();
            IOUtils.write(bytes, outputStream);
        }
    }

测试一下！！！！

**上传！**

![format_png][]

浏览器访问一下

![format_png 1][]

**删除！把之前的照片删掉！**

**![format_png 2][]**

再通过浏览器访问，应该就是404，记得清除浏览器缓存哦！

![format_png 3][]

**下载！记得再上传一张照片，如果服务器有照片请忽略！**

![format_png 4][]

注意一下上传路径，fastFileStorageClient会加上你的服务器地址+ip，只需要刚刚上传成功路径即可！

ok，全部都大功告成了，拜拜！有啥问题群里联系我！
