Spring AMQP接收器的参数类型错误

我的Spring AMQP应用程序在启动时记录了以下异常:

org.springframework.amqp.rabbit.listener.exception.ListenerExecutionFailedException: Failed to invoke target method 'receiveMessage' with argument type = [class [B], value = [{[B@660cff44}]

以下是相关代码段:

@Bean
public MessageConverter jsonMessageConverter(){
    return new Jackson2JsonMessageConverter();
}

@Bean
Queue queue() {
    return new Queue(config.getAMQPResultsQueue(), false);
}

@Bean
TopicExchange exchange() {
    return new TopicExchange(config.getAMQPResultsExchange());
}

@Bean
Binding binding(Queue queue, TopicExchange exchange) {
    return BindingBuilder.bind(queue).to(exchange).with("#");
}

@Bean
SimpleMessageListenerContainer container(ConnectionFactory connectionFactory, MessageListenerAdapter listenerAdapter) {
    SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
    container.setConnectionFactory(connectionFactory);
    container.setQueueNames(config.getAMQPResultsQueue());
    container.setMessageListener(listenerAdapter);
    container.setMessageConverter(jsonMessageConverter());
    return container;
}

@Bean
MessageListenerAdapter listenerAdapter(Receiver receiver) {
    return new MessageListenerAdapter(receiver, "receiveMessage");
}

和

@Component
public class Receiver {
    public void receiveMessage(String message) {
        System.out.println("Received <" + message + ">");
    }
}
