示例1: attachSnapshotTags

import com.amazonaws.services.ec2.model.Snapshot; //导入依赖的package包/类
void attachSnapshotTags(AmazonEC2Async client, String sourceSnapshotId, String snapshotId) {

		DescribeSnapshotsResult result = client
				.describeSnapshots(new DescribeSnapshotsRequest().withSnapshotIds(sourceSnapshotId));
