我在heroku上托管了一个多模块项目，并在尝试运行我的Spring Boot应用程序时收到以下错误。

我看到的问题是，它正在尝试连接一些localhost，而我在heroku中添加了我的插件CloudAMQP
Little Lemur，我已将这些添加到我的两个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，我有这段代码：
@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);
}
}
并在我的worker模块主方法中：
public class SpringBootHerokuExampleApplication {
public final static String PDF_MERGE_QUEUE= "pdf-merge-queue";
public static void main(String[] args) {
SpringApplication.run(SpringBootHerokuExampleApplication.class, args);
}
}

当我在yml文件中明确指定主机名时，为什么要尝试连接到localhost？有什么想法吗？
答案 0 :(得分：1)
刚刚发现在yml文件中我有一个名为heroku的配置文件，当我删除它时，它连接到给定主机中的RabbitMQ。

如果您使用的是spring boot，可以通过spring cloud stream配置Rabbit。 在这种情况下，您不必配置bean，配置也更容易：
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
然后你必须创建监听器：
@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
}
}
在这种情况下，我的应用程序是从同一个交易所编写和接收的 和队列（因为测试的东西）
如果要按照显示的方式配置Rabbit，请尝试使用队列的bean创建配置类，使用@Configuration进行交换和绑定。不要在app类中声明bean。
它似乎无法读取队列的autodelete属性，但如果我没有错，我应该采用默认值。 也许您有网络问题 检查rabbitmq并重新启动
您可以访问rabbitMq管理员界面吗？
关于whi尝试连接localhost的评论将此添加到您的bean定义中：
@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;
}
还会移除application.yml的地址

完美，我认为您配置的弹簧配置文件适用于多种环境。 感谢您的回应，以帮助解决另一个人的问题。
