我目前正在努力解决一个公平的问题.我想从RabbitMQ收到一条消息,并将其转换为字符串(或稍后的json对象).但我得到的只是字节数.

配置类(使用弹簧)

@Configuration
public class RabbitConfiguration {

    @Bean
    public CachingConnectionFactory connectionFactory() {
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory("www.example.com");
        connectionFactory.setUsername("xxxx");
        connectionFactory.setPassword("xxxx");
        return connectionFactory;
    }

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

    @Bean
    public SimpleMessageListenerContainer messageListenerContainer(){
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(connectionFactory());
        container.setAutoStartup(false);
        container.setQueues(indexQueue());
        container.setConcurrentConsumers(1);
        container.setAcknowledgeMode(AcknowledgeMode.AUTO);
        container.setMessageListener(new MessageListenerAdapter(pageListener(), jsonMessageConverter()));
        return container;
    }

    @Bean
    public Queue indexQueue(){
        return new Queue("pages.type.index");
    }

    @Bean
    public MessageListener pageListener(){
        return new PageQueueListener(); …
