以下代码用于设置文件元信息：

public void testObjectMeta() {

try {

// Upload a text string as a new object.

s3.putObject(bucketName, objectName, "Uploaded String Object");

// Upload a file as a new object with ContentType and title specified.

PutObjectRequest request = new PutObjectRequest(bucketName, objectName, new File(filePath));

ObjectMetadata metadata = new ObjectMetadata();

metadata.setContentType("plain/text");

metadata.addUserMetadata("x-amz-meta-title", "someTitle");

request.setMetadata(metadata);

s3.putObject(request);

}

catch(AmazonServiceException e) {

System.err.println(e.getErrorMessage());

}

}
