How "Java-oss" Uploads files using OSS in Spring-boot projects __java

Preparatory work:

1. Apply for OSS you will get Endpoint,accesskeyid,bucketname,accesskeysecret

2. Introduction of OSS maven dependency:com.aliyun.oss:aliyun-sdk-oss:jar:2.5.0

3. Create Ossclient

@Bean

Public Ossclient createossclient () {

Ossclient client = new Ossclient (endpoint, Accesskeyid, Accesskeysecret);

return client;

}

4. Upload file:

InputStream is=new bytearrayinputstream (bytes);

Logger.info ("Key is:" + key+ "corresponds to Bucket:" +bucketname);

Putobjectresult result = Ossclient.putobject (Bucketname, Key, is);

Logger.info (json.tojsonstring (result));

5. Download the file:

Download pictures

Ossobject ossobject = Ossclient.getobject (Bucketname, Fileid);

Response.setcharacterencoding ("Utf-8");

Sets the file encoding returned

Response.setcontenttype ("Image/png;image/gif;image/jpeg;image/bmp");

try {

Response.getoutputstream (). Write (Ioutils.tobytearray (Ossobject.getobjectcontent ()));

catch (IOException e) {

Logger.error ("File download Error", E);

throw new Campusguardexception ("File download Error");

}
