二.application.yml

#fastdfs 配置
fdfs:
so-timeout: 150000
connect-timeout: 150000 #超时时间
thumb-image:
width: 150
height: 150
tracker-list:
- 111.111.111.111:22122 #ip:端口号
spring:
thymeleaf:
prefix: classpath:/templates/
servlet:
multipart:
max-file-size: 50MB #单次单个文件最大大小
max-request-size: 50MB #单次上传所有文件的总大小
　　#注意，这里springboot默认配置的大小是1MB和10MB，可能不够用，具体参考MultipartProperties.java

三.FastUtil.java 前提先将Nginx和FastDFS整合

@Component
public class FastUtil {
 
  private final Logger logger = LoggerFactory.getLogger(FastUtil.class);
 
  @Autowired
  private FastFileStorageClient fastFileStorageClient;
 
  
  public String uploadFile(byte[] bytes, long fileSize, String extension) {
    ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes);
    StorePath storePath = fastFileStorageClient.uploadFile(byteArrayInputStream, fileSize, extension, null);
    return "http://111.111.111.111/"+storePath.getFullPath();
  }
 
  public byte[] downloadFile(String group,String path) throws IOException {
    DownloadByteArray downloadByteArray = new DownloadByteArray();
    byte[] bytes = fastFileStorageClient.downloadFile(group, path, downloadByteArray);
    return bytes;
  }
 
}

四.配置类 FdfsConfig.java

@Configuration
@import(FdfsClientConfig.class)
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
public class FdfsConfig {
}

五.Controller

@RestController
public class FdfsController {
 
  @Autowired
  private FastUtil fastDFSClientWrapper;
 
  private final Logger logger = LoggerFactory.getLogger(FdfsController.class);
 
  @PostMapping("/upload")
  @ResponseBody
  public String upload(MultipartFile file) throws Exception {
    byte[] bytes = new byte[0];
    try {
      bytes = file.getBytes();
    } catch (IOException e) {
      logger.error("获取文件错误");
      e.printStackTrace();
    }
    //获取源文件名称
    String originalFileName = file.getOriginalFilename();
    //获取文件后缀--.doc
    String extension = originalFileName.substring(originalFileName.lastIndexOf(".") + 1);
    String fileName = file.getName();
    //获取文件大小
    long fileSize = file.getSize();
    System.out.println(originalFileName + "==" + fileName + "==" + fileSize + "==" + extension + "==" + bytes.length);
    String string = fastDFSClientWrapper.uploadFile(bytes, fileSize, extension);
    return string;
  }
}

六.前端页面 index.html

  
  


文件上传

七.开始上传

最后在页面上返回一个URL，可以直接访问
