PutObject是否在AmazonS3Client中阻塞？

Question

你知道的方法 -

public PutObjectResult putObject(PutObjectRequest putObjectRequest) 

在AmazonS3Client拦截？

Answer 1

是的，它是阻塞的，它返回一个结果。如果你想要做更复杂的上传，看看这个：

DefaultAWSCredentialsProviderChain credentialProviderChain = new DefaultAWSCredentialsProviderChain(); 
TransferManager tx = new TransferManager(
      credentialProviderChain.getCredentials()); 
Upload myUpload = tx.upload(myBucket, myFile.getName(), myFile); 

// You can poll your transfer's status to check its progress 
if (myUpload.isDone() == false) { 
    System.out.println("Transfer: " + myUpload.getDescription()); 
    System.out.println(" - State: " + myUpload.getState()); 
    System.out.println(" - Progress: " 
        + myUpload.getProgress().getBytesTransferred()); 
} 

// Transfers also allow you to set a <code>ProgressListener</code> to receive 
// asynchronous notifications about your transfer's progress. 
myUpload.addProgressListener(myProgressListener); 

// Or you can block the current thread and wait for your transfer to 
// to complete. If the transfer fails, this method will throw an 
// AmazonClientException or AmazonServiceException detailing the reason. 
myUpload.waitForCompletion(); 

// After the upload is complete, call shutdownNow to release the resources. 
tx.shutdownNow();
