1、首先新建一個SpringBoot Maven 項目
pom 依賴如下
<!-- https://mvnrepository.com/artifact/com.github.tobato/fastdfs-client -->
<dependency>
<groupId>com.github.tobato</groupId>
<artifactId>fastdfs-client</artifactId>
<version>1.26.7</version>
</dependency>
2、配置相關規則
/**
* @ConfigurationProperties:用於讀取yml文件或properties文件的值
* 其他類可以通過@EnableConfigurationProperties直接加載
*
* @author wcong
* @version 1.0
* @date 2020-05-06 13:53
*/
@Data
@ConfigurationProperties(prefix = "upload")
@Component
public class UploadProperties {
private String baseUrl;
private List<String> allowTypes;
}
3、yml 文件
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 服務地址，可配置多個
- 391.106.941.239:22122
upload:
base-url: http://391.106.941.239:900/
allow-types: # miniTypes參考：https://www.w3school.com.cn/media/media_mimeref.asp
- image/jpeg
- image/png
- image/bmp
- image/gif
4、UploadService
/**
* @author wcong
* @version 1.0
* @date 2020-05-06 14:15
*/
@Service
@Slf4j
@EnableConfigurationProperties(UploadProperties.class)
public class UploadService {
@Autowired
private FastFileStorageClient storageClient;
@Autowired
private UploadProperties uploadProperties;
public String uploadImage(MultipartFile file) {
// 1、校驗文件類型
String contentType = file.getContentType();
if (!uploadProperties.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 uploadProperties.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、UploadController
/**
* @author wcong
* @version 1.0
* @date 2020-05-06 14:27
*/
@RestController
@RequestMapping("upload")
public class UpoadController {
@Autowired
private UploadService uploadService;
@PostMapping("/doUpload")
public Map<String,Object> doUpload(MultipartFile file){
Map<String,Object> map = new HashMap<>();
String filePath = uploadService.uploadImage(file);
map.put("path",filePath);
return map;
}
}
6、index.html 測試
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>文件圖片到fastDFS服務器</title>
</head>
<body>
<h1>上傳圖片</h1>
<form action="/upload/doUpload" method="post" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" value="上傳">
</form>
</body>
</html>
7、查看測試結果
返回值：
