Microservices AmqpConnectException:ConnectException:连接被拒绝：连接

根据Josh Long在Youtube上的教程，尝试Spring Cloud向RabbitMQ发送消息

操作系统：Windows

GIT URL:

我导入了预订客户端、eureka服务、配置服务。我成功地启动了所有服务

每次我使用JSON负载访问服务时，都会收到下面的错误消息

输入URL: 正文：

{“reservationName”：“Dr.Who”}

输出JSON:

{
    "timestamp": 1521277278436,
    "status": 500,
    "error": "Internal Server Error",
    "exception": "org.springframework.amqp.AmqpConnectException",
    "message": "java.net.ConnectException: Connection refused: connect",
    "path": "/reservations"
}

我在控制台中得到以下错误

即使使用Kafka而不是RabbitMQ绑定器，也会出现连接错误

---

有人能帮忙吗？所有示例似乎都是在基于unix的平台上实现的。请提供帮助。

这仅仅意味着您没有安装RabbitMQ，或者它没有在默认主机（localhost:5672）上运行。与Kafka一样，您需要安装并运行代理

---

我看到Josh提供了一个docker-compose.yml来在docker映像中运行RabbitMQ，或者您可以将RabbitMQ作为服务安装。

我还没有安装RabbitMQ或Kafka。我正在使用适当的绑定，因此我猜我不需要安装RabbitMQ或Kafka？我能在不安装RabbitMQ或Kafka的情况下完成这项工作吗；你不能；绑定器将目标“绑定”到必须存在的代理。提供一个嵌入式kafka代理（通常用于测试），这是可能的，因为kafka是用Scala编写并在JVM中运行的。RabbitMQ是用Erlang编写的，不能在JVM中运行。有一个示例展示了如何使用嵌入式kafka代理进行测试。非常感谢。我将安装RabbitMQ并继续。感谢您对嵌入式卡夫卡的建议：）
