spring boot 无法连接rabbitmq

Question

我有一个这样的 RabbitMQ 服务器

当我尝试通过 Spring Boot amqp 连接到此服务器时，我看到com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile. com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile.

我的配置是这个

# Message
spring.activemq.broker-url=tcp://127.0.0.1:5672
spring.activemq.user=test
spring.activemq.password=test

是的，用户 test 可以访问 / 上的虚拟主机，是的，我可以在 RabbitMQ GUI 上使用 test/test 登录

编辑

查看rabbitmq日志，我看到了这个

{handshake_error,starting,0,
             {amqp_error,access_refused,
                         "PLAIN login refused: user 'guest' - invalid credentials",
                         'connection.start_ok'}}

似乎 Spring 忽略了我的配置并尝试与guest连接

Answer 1

src/main/resources/application.yml

spring:
  rabbitmq:
    user: guest
    password: guest
    host: rabbitmq
    port: 5672
    virtual-host: someVirtualHost

Answer 2

Spring 属性包括 RabbitMQ 的特定设置。 尝试用下面的替换你的 ActiveMQ 配置。

例子：

spring.rabbitmq.host = 127.0.0.1
spring.rabbitmq.port = 5672
spring.rabbitmq.username = guest
spring.rabbitmq.password = guest

Answer 3

尝试在 spring boot properties 中更改您的 rabbitMQ 配置：

spring.rabbitmq.host = 127.0.0.1
spring.rabbitmq.port = 5672
spring.rabbitmq.username = guest
spring.rabbitmq.password = guest

Answer 4

使用 springboot 的默认设置是好的，但如果我们想将外部兔子实例添加到 spring 容器，那么我们应该遵循如下

应用程序.yml

rabbitmq:
  host: 'hostname'
  vhost: 'vhostname'
  user: 'userName'
  password: 'passwd'
  port: 5672

配置类

        @Configuration
    public class RabbitConfig {

        @Value("${rabbitmq.host}")
        private String host;
        @Value("${rabbitmq.vhost}")
        private String vhost;
        @Value("${rabbitmq.user}")
        private String user;
        @Value("${rabbitmq.password}")
        private String password;
        @Value("${rabbitmq.port}")
        private int port;

        @Bean
        public ConnectionFactory connectionFactory() {
            CachingConnectionFactory factory = new CachingConnectionFactory();
            System.out.println("rmqhost is " + host);
            factory.setHost(host);
            factory.setVirtualHost(vhost);
            factory.setUsername(user);
            factory.setPassword(password);
            factory.setPort(port);
            return factory;
        }

        @Bean
        public RabbitAdmin rabbitAdmin() {
            return new RabbitAdmin(connectionFactory());
        }

    }

我们可以为 rabbitmqtemplate 或 rabbitmqListener 创建 Bean
