Spring amqp - 未找到相容的身份驗證機制 - 提供伺服器-Java-PHP中文網

php小編新一今天為大家介紹的是Spring AMQP，它是一種基於AMQP協定的訊息傳遞框架。然而，有時在使用Spring AMQP時，我們可能會遇到一個錯誤：「未找到相容的身份驗證機制 - 提供伺服器」。這個錯誤提示可能會讓人感到困惑，不知道該如何解決。接下來，我們將詳細解釋這個錯誤的原因，並提供解決方案，幫助大家順利使用Spring AMQP框架。

問題內容

我正在嘗試透過外部驗證機制將spring boot 應用程式連接到rabbit mq (https://github.com/rabbitmq/rabbitmq-auth-mechanism-ssl) 。

我收到以下錯誤：

rabbitmq版本：rabbitmq:3.12.1-management

rabbitmq.conf 包含這些屬性：

default_user=guest
default_pass=guest
listeners.tcp=none
listeners.ssl.default=5672
ssl_options.cacertfile=/etc/rabbitmq/cert/ca_bundle.pem
ssl_options.certfile=/etc/rabbitmq/cert/certificate.pem

我宣告了以下方法來包含 sasl 設定：

@Bean
  public AmqpTemplate amqpTemplate(ConnectionFactory connectionFactory) {
    CachingConnectionFactory cachingConnectionFactory = (CachingConnectionFactory) connectionFactory;
    cachingConnectionFactory.getRabbitConnectionFactory().setAutomaticRecoveryEnabled(true);
    cachingConnectionFactory.getRabbitConnectionFactory().setSaslConfig(DefaultSaslConfig.EXTERNAL);
    cachingConnectionFactory.resetConnection();

    RabbitTemplate rabbitTemplate = new RabbitTemplate(cachingConnectionFactory);
    rabbitTemplate.setMessageConverter(converter());
    return rabbitTemplate;
  }

解決方法

我不確定rabbitmq 配置端的listeners.ssl.default=5672 是什麼，但聽起來您將預設的ssl 連接埠覆蓋到該端口。

spring boot中的邏輯是這樣的：

return (optional.ofnullable(getssl().getenabled()).orelse(false)) ? default_port_secure : default_port;

登入後複製

地點：

private static final int default_port_secure = 5671;

登入後複製

因此，可能需要考慮明確提供該連接埠：

spring.rabbitmq.port=5672

登入後複製

您可能也不需要自訂rabbittemplate bean，只需新增connectionfactorycustomizer 即可將defaultsaslconfig.external 設定為自動配置的com .rabbitmq.client.connectionfactory。

也不建議使用 setautomaticrecoveryenabled(true): //m.sbmmt.com/link/3c0de3fec9ab8a3df01109251f137119
