我目前正在学习RabbitMQ和Spring AMPQ。我本周尝试了一些示例，但在配置的某些步骤中遇到了问题。
我有这个docker-compose文件：
app:
build: .
environment:
INSERTION_QUEUE: insertion.queue
VALIDATION_QUEUE: validation.queue
NUMBER_OF_VALIDATION_CONSUMERS: 1
RESPONSE_EXCHANGE: response.exchange
RESPONSE_ROUTING_KEY: response.routing.key
RABBITMQ_HOST: rabbitmq
RABBITMQ_PORT: 5672
RABBITMQ_VHOST: /
RABBITMQ_USERNAME: guest
RABBITMQ_PASSWORD: guest
JDBC_URL: jdbc:mysql://mysql:3306/hided
links:
- mysql:mysql
- rabbitmq:rabbitmq
mysql:
image: mysql:5.7
environment:
MYSQL_DATABASE: hided
MYSQL_ROOT_PASSWORD: secret
rabbitmq:
image: rabbitmq:3.6-management
ports:
- 15672:15672
并且我复制了此示例，在其中添加了Maven配置：https://github.com/spring-guides/gs-messaging-rabbitmq/tree/master/complete
通过用户名和密码“ guest”正确地通过URL localhost：15672访问RabbitMQ
但是当我运行此示例时，它给了我这个错误（我认为重要的消息是Broker不可用；无法在启动期间强制执行队列声明：java.net.ConnectException：连接被拒绝：connect）：] >

@Bean public ConnectionFactory connectionFactory() { CachingConnectionFactory connectionFactory = new CachingConnectionFactory(); connectionFactory.setHost("localhost"); connectionFactory.setVirtualHost("/"); connectionFactory.setUsername("guest"); connectionFactory.setPassword("guest"); return connectionFactory; }我确实尝试过其他示例，但我仍然面临同样的错误。
我的Dockerfile是：
# Start with a base image containing Java runtime FROM openjdk:8-jdk-alpine # Add Maintainer Info LABEL maintainer="hidden" # Add a volume pointing to /tmp VOLUME /tmp ARG JAR_FILE=target/*.jar COPY ${JAR_FILE} app.jar ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]我的application.properties是：

我目前正在学习RabbitMQ和Spring AMPQ。我本周尝试了一些示例，但是在配置的某些步骤中遇到了问题。我有这个docker-compose文件：app：build：。 ...
我今天发现了错误，我们需要在docker-compose文件中公开RabbitMQ端口，否则将无法访问。因此我们需要在rabbitmq> ports
请更正您应替换为的bean创建配置
