1、創建SpringBoot項目
項目名fastdfs-springboot
githun地址：
導入 fastdfs-client 依賴，記得導入web依賴
<dependency>
<groupId>com.github.tobato</groupId>
<artifactId>fastdfs-client</artifactId>
<version>1.26.7</version>
</dependency>
修改application.yml
IP地址記得修改爲自己的。
fdfs:
so-timeout: 2500 # 讀取時間
connect-timeout: 600 # 連接超時時間
thumb-image: # 縮略圖
width: 100
height: 100
tracker-list: # tracker服務配置地址列表
- 192.168.202.128:22122
upload:
base-url: http://192.168.202.128/
#配置允許的文件的類型
allow-types:
- image/jpeg
- image/png
- image/bmp
注：
- 服務器地址，記得修改
- 查看文件的類型，

2、創建前端頁面 static/index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>FastDFS 測試</title>
</head>
<body>
<form action="/upload/doUpload" method="post" enctype="multipart/form-data">
<input type="file" name="mf"/>
<input type="submit" value="上傳"/>
</form>
</body>
</html>
3、創建配置類
@Component
@ConfigurationProperties(prefix = "upload")
@Data
public class UploadProperties {
private String baseUrl;
private List<String> allowTypes;
}
4，創建服務類
注入FastFileStorageClient後，可以直接調用其uploadFile()。
比上一種方法省去了手動設置配置信息，也不需要自己建立tracker連接、獲取storage、再獲得storageClient這些準備工作。
@Service
@EnableConfigurationProperties(UploadProperties.class)
public class UploadService {
private Log log= LogFactory.getLog(UploadService.class);
@Autowired
private FastFileStorageClient storageClient;
@Autowired
private UploadProperties prop;
public String uploadImage(MultipartFile file) {
// 1、校驗文件類型
String contentType = file.getContentType();
if (!prop.getAllowTypes().contains(contentType)) {
throw new RuntimeException("文件類型不支持");
}
// 2、校驗文件內容
try {
BufferedImage image = ImageIO.read(file.getInputStream());
if (image == null || image.getWidth() == 0 || image.getHeight() == 0) {
throw new RuntimeException("上傳文件有問題");
}
} catch (IOException e) {
log.error("校驗文件內容失敗....{}", e);
throw new RuntimeException("校驗文件內容失敗"+e.getMessage());
}
try {
// 3、上傳到FastDFS
// 3.1、獲取擴展名
String extension = StringUtils.substringAfterLast(file.getOriginalFilename(), ".");
// 3.2、上傳
StorePath storePath = storageClient.uploadFile(file.getInputStream(), file.getSize(), extension, null);
// 返回路徑
return prop.getBaseUrl() + storePath.getFullPath();
} catch (IOException e) {
log.error("【文件上傳】上傳文件失敗！....{}", e);
throw new RuntimeException("【文件上傳】上傳文件失敗！"+e.getMessage());
}
}
}
5，創建UploadController
@RestController
@RequestMapping("upload")
public class UploadController {
@Autowired
private UploadService uploadService;
@RequestMapping("doUpload")
@ResponseBody
public Map<String,Object> doUpload(MultipartFile mf){
System.out.println(mf.getOriginalFilename());
Map<String, Object> upload =new HashMap<>();
String filePath= this.uploadService.uploadImage(mf);
upload.put("path",filePath);
return upload;
}
}
