You can define a SimpleMessageListenerContainerFactory bean and configure the listener behavior as follows:

@Bean
public SimpleMessageListenerContainerFactory simpleMessageListenerContainerFactory(AmazonSQSAsync amazonSqs) {
    SimpleMessageListenerContainerFactory factory = new SimpleMessageListenerContainerFactory();
    [...]
    factory.setAmazonSqs(amazonSqs);
    factory.setMaxNumberOfMessages(1);
    [...]

    return factory;
}
