解决方法如下所示,使用AWS Java SDK中的连接池等待连接超时的代码示例:
import com.amazonaws.AmazonClientException;
import com.amazonaws.AmazonServiceException;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.model.GetObjectRequest;
import com.amazonaws.services.s3.model.S3Object;
public class S3GetObjectWithTimeout {
public static void main(String[] args) throws InterruptedException {
String bucketName = "my-bucket";
String key = "my-object-key";
// Create S3 client with connection pool configuration
AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
.withCredentials(new ProfileCredentialsProvider())
.withMaxConnections(10) // Set the maximum number of connections in the connection pool
.withConnectionTimeout(3000) // Set the connection timeout in milliseconds
.build();
// Make a GET request to retrieve the object
try {
S3Object object = s3Client.getObject(new GetObjectRequest(bucketName, key));
// Process the object here
// ...
} catch (AmazonServiceException e) {
// Handle Amazon service exception
e.printStackTrace();
} catch (AmazonClientException e) {
// Handle Amazon client exception
e.printStackTrace();
}
}
}
上述代码示例中,我们首先创建了一个使用连接池的AmazonS3客户端。通过设置withMaxConnections
方法,我们可以指定连接池中的最大连接数。使用withConnectionTimeout
方法,我们可以设置连接超时时间,单位为毫秒。
在try
块中,我们可以发起GET请求来检索S3存储桶中的对象。如果出现Amazon服务异常或客户端异常,我们可以在catch
块中进行适当的处理。
请注意,以上代码仅为示例,您需要根据您的实际需求进行适当的修改。
