我有一个Spring Boot应用程序与rabbitmq代理连接,后者设法启动正常,但无论队列中是否有消息,我都会获得消息使用者的持续启动/关闭。下面是我的应用程序日志和客户端类的副本:

以下是我的客户类的副本:
public class RabbitClientConfiguration extends AbstractEMCRabbitConfiguration {
@Inject
private JacksonConfiguration jacksonConfiguration;
@Inject
private MessagingConfiguration messagingConfiguration;
//@Value("${data.core.pattern}")
//private String coreDataRoutingKey;
//@Inject
//private ClientHandler clientHandler;
@Override
public void configureRabbitTemplate(RabbitTemplate rabbitTemplate) {
rabbitTemplate.setRoutingKey(MAC_REQUEST_ROUTING_KEY);
}
@Bean
public SimpleMessageListenerContainer messageListenerContainer(){
SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
container.setConnectionFactory(connectionFactory());
container.setQueueNames(MAC_REQUEST_QUEUE_NAME);
container.setMessageListener(messageListenerAdapter());
container.setAcknowledgeMode(AcknowledgeMode.AUTO);
return container;
}
@Bean
MessageListenerAdapter messageListenerAdapter(){
return new MessageListenerAdapter(clientHandler(jacksonConfiguration.objectMapper(),messagingConfiguration.macMessageHandler(messagingConfiguration.messagingFactory())),jsonMessageConverter());
//return new MessageListenerAdapter(clientHandler,"receiveMessage");
}
@Bean
ClientHandler clientHandler(ObjectMapper objectMapper, IMessageHandler macMessageHandler){
ClientHandler clientHandler = new ClientHandler();
clientHandler.setObjectMapper(objectMapper);
clientHandler.setMacMessageHandler(macMessageHandler);
return clientHandler;
}
@Bean
public AmqpAdmin rabbitAdmin() { return new RabbitAdmin(connectionFactory());}
}
答案 0 :(得分:0)
java.lang.NullPointerException:null at com.rabbitmq.client.impl.ChannelN.validateQueueNameLength
这意味着MAC_REQUEST_QUEUE_NAME
包含null
- 看起来容器在您调用setter时不会检查它。
我打开JIRA Issue来检测这种情况。
