Advanced AmazonSNSClient configuration
If your Camel Application is running behind a firewall or if you need to have more control over the AmazonSNSClient configuration, you can create your own instance:
AWSCredentials awsCredentials = new BasicAWSCredentials("myAccessKey", "mySecretKey"); ClientConfiguration clientConfiguration = new ClientConfiguration(); clientConfiguration.setProxyHost("http://myProxyHost"); clientConfiguration.setProxyPort(8080); AmazonSNSClient client = new AmazonSNSClient(awsCredentials, clientConfiguration);
and refer to it in your Camel aws-sns component configuration:
from("direct:start") .to("aws-sns://MyTopic?amazonSNSClient=#amazonSNSClient");
Dependencies
Maven users will need to add the following dependency to their pom.xml.
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-aws</artifactId> <version>${camel-version}</version> </dependency>
where ${camel-version
} must be replaced by the actual version of Camel (2.8 or higher).
