問題描述

我在heroku上托管了一個多模塊項目，並在嘗試運行Spring Boot Application時收到以下錯誤。

我看到的問題是，它正在嘗試連接一些本地主機，而我的插件CloudAMQP Little Lemur添加到heroku中，並且已將它們添加到我的兩個Application.yml文件中： 

spring:
    profiles: heroku
    mvc:
      async:
        request-timeout: 3600000
    rabbitmq:
      addresses: amqp://****:*****@puma.rmq.cloudamqp.com/uyjgxslh
      host: puma.rmq.cloudamqp.com
      port: 1883
      username: ****:****
      password: *****

在我的webModule中，我有以下代碼： 

@SpringBootApplication
public class SpringBootHerokuExampleApplication {

    public final static String PDF_MERGE_QUEUE= "pdf-merge-queue";

    @Bean
    Queue queue(){
        return new Queue(PDF_MERGE_QUEUE, false);
    }

    @Bean
    TopicExchange exchange(){
        return new TopicExchange("pdf-nerge-exchange");
    }

    @Bean
    Binding binding(Queue queue, TopicExchange topicExchange){
        return BindingBuilder.bind(queue).to(topicExchange).with(PDF_MERGE_QUEUE);
    }

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

    @Bean
    MessageListenerAdapter listenerAdapter(RabbitMQListener rabbitMQListener){
        return new MessageListenerAdapter(rabbitMQListener, "receiveMessage");
    }

    public static void main(String[] args) {
        SpringApplication.run(SpringBootHerokuExampleApplication.class, args);
    }
}

在我的工作人員模塊的主要方法中： 

public class SpringBootHerokuExampleApplication {
    public final static String PDF_MERGE_QUEUE= "pdf-merge-queue";
    public static void main(String[] args) {
        SpringApplication.run(SpringBootHerokuExampleApplication.class, args);
    }
}

請在下面從Heroku日志中找到更多堆棧跟蹤：

當我在yml文件中明確指定主機名時，為什么要嘗試連接到localhost？ 任何的想法？

2 個解決方案

解決方案1
 1 已采納  2018-06-13 07:32:39

剛剛發現，在yml文件中，我有一個名為heroku的配置文件，當我刪除它時，它連接到給定主機中的RabbitMQ。

如果您使用的是Spring Boot，則可以按Spring Cloud Stream配置Rabbit。 在這種情況下，您不必配置Bean，並且配置更加容易： 

spring:
#---------------- RabbitMQ -----------------#
  rabbitmq:
    #Default username ans pass
    dynamic: true
    host: localhost
    port: 5672
    username: guest
    password: guest

#---------------------------- RabbitMQ properties Commons ------------------------------#
  cloud:
    stream:
      bindings:
        springCloudBusInput:
          destination: InputExchange
          group: Queue
          producer:
            exchangeAutoDelete: false
        springCloudBusOutput:
          destination: InputExchange
          group: Queue
          consumer:
            exchangeAutoDelete: false

然后，您必須創建偵聽器： 

@Component
public class RemoteEventListener implements ApplicationListener<InputEvent> {

    @Override
    public void onApplicationEvent(InputEvent inputEvent) {

        //whatever you want to do when a InputEvent Type is received in the queue

    }
}

在這種情況下，我的應用正在從相同的交換和隊列中進行寫入和接收（因為進行了測試）

如果要按照顯示的方式配置Rabbit，請嘗試使用隊列Bean創建配置類，並使用@Configuration進行交換和出價。 不要在應用程序類中聲明bean。

似乎無法讀取隊列的autodelete屬性，但是如果我沒有記錯，我應該使用默認值。 也許您 遇到 網絡問題 檢查rabbitmq並重新啟動它

您可以訪問RabbitMq管理員界面嗎？

關於有關whi試圖與localhost連接的注釋，請將其添加到您的bean定義中： 

@Autowired
 private ConnectionFactory rabbitConnectionFactory

@Bean
 public RabbitTemplate rubeExchangeTemplate() {
  RabbitTemplate r = new RabbitTemplate(rabbitConnectionFactory);
  r.setExchange("rmq.rube.exchange");
  r.setRoutingKey("rube.key");
  r.setConnectionFactory(rabbitConnectionFactory);
  return r;
 }

還要刪除您的應用程序的地址。yml
