關於七牛雲的註冊以及申請存儲空間這裏就不詳細介紹了，網上的教程很多而且註冊以及申請存儲空間也是比較簡單的。直接進入正題，說一下整合的事情。
配置文件application.yml
qiniu:
accessKey: xxxx-xxxx-xxxx
secretKey: xxxx_xxxx-xxxx
bucket: rongdi
path: http://up-z1.qiniup.com # 每個地區的地址都不一樣
上面參數對應七牛雲中的配置如下圖
創建上傳文件以及圖片的配置類
@Data
@Component
@ConfigurationProperties(prefix = "qiniu")
public class QiNiuYunConfig {
@Value("${accessKey}")
private String accessKey;
@Value("${secretKey}")
private String secretKey;
@Value("${bucket}")
private String bucket;
@Value("${path}")
private String path;
public String uploadImgToQiNiu(FileInputStream file, String filename) {
// 構造一個帶指定Zone對象的配置類，注意後面的zone各個地區不一樣的
Configuration cfg = new Configuration(Zone.zone1());
// 其他參數參考類註釋
UploadManager uploadManager = new UploadManager(cfg);
// 生成密鑰
Auth auth = Auth.create(accessKey, secretKey);
try {
String upToken = auth.uploadToken(bucket);
try {
Response response = uploadManager.put(file, filename, upToken, null, null);
// 解析上傳成功的結果
DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class);
// 這個returnPath是獲得到的外鏈地址,通過這個地址可以直接打開圖片
String returnPath = getPath() + "/" + putRet.key;
return returnPath;
} catch (QiniuException ex) {
Response r = ex.response;
System.err.println(r.toString());
try {
System.err.println(r.bodyString());
} catch (QiniuException ex2) {
//ignore
}
}
} catch (Exception e) {
e.printStackTrace();
}
return "";
}
}
Controller層
@Controller
public class QiNiuYunController {
@Autowired
private QiNiuYunConfig qiNiuYunConfig;
@GetMapping("/upload")
public String upload(){
return "upload";
}
@PostMapping("/qiniu")
public String qiNiuYunUpload(@RequestParam("file")MultipartFile file,
Model model) throws IOException {
String filename = file.getOriginalFilename();
FileInputStream inputStream = (FileInputStream) file.getInputStream();
//爲文件重命名：uuid+filename
filename = UUID.randomUUID()+ filename;
String link = qiNiuYunConfig.uploadImgToQiNiu(inputStream, filename);
model.addAttribute("link", link);
return "upload";
}
}
HTML代碼
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>上傳文件</title>
</head>
<body>
<form action="/qiniu" method="post" enctype="multipart/form-data">
<label>上傳圖片</label>
<input type="file" name="file"/>
<input type="submit" value="上傳"/>
<p>回顯圖片:</p>
<img th:src="${link}"/>
</form>
</body>
</html>
效果如下
