需要導入的dependency
後兩個依賴主要是用于實作Bucket的建立以及檔案的上傳
1 <dependency>
2 <groupId>com.aliyun.oss</groupId>
3 <artifactId>aliyun-sdk-oss</artifactId>
4 <version>3.10.2</version>
5 </dependency>
6 <dependency>
7 <groupId>commons-io</groupId>
8 <artifactId>commons-io</artifactId>
9 <version>1.3.2</version>
10 </dependency>
11 <dependency>
12 <groupId>commons-fileupload</groupId>
13 <artifactId>commons-fileupload</artifactId>
14 <version>1.2.1</version>
15 </dependency> 加載完相關依賴後，便可以通過建立OSSClient對象調用相關接口實作相關功能啦.
注意：在沒有綁定私有域名的情況下，檔案上傳成功後傳回的url隻能是下載下傳連結...
代碼如下： 1 package com.aliyun.oss;

27 OSSClient ossClient = new OSSClient(EndPoint,AccessKeyID,AccessKeySecret);
28 if(ossClient.doesBucketExist(BucketName)) {
29 System.out.println("success");
30 //關閉oss的連接配接 此處不要關閉，後面會調用，不然會報錯

36 bucketRequest.setCannedACL(CannedAccessControlList.PublicRead); //設定通路權限 --公共讀
37 ossClient.createBucket(bucketRequest); //映射原理，會重新生成一個ossClient并覆寫目前的ossClient

啊，圖檔應該不違規吧 QAQ
