RabbitMQ错误java.util.concurrent.TimeoutException:空

出现这个问题 RabbitMQ错误java.util.concurrent.TimeoutException:空的原因是

application properties文件中端口号没配置对

spring.rabbitmq.host=localhost
spring.rabbitmq.port=15672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

server.port=3033

导致出现Error

Servlet.service()for servlet [dispatcherServlet] in context withpath[] threw exception [Request processing failed; nested exception is org.springframework.amqp.AmqpTimeoutException:java.util.concurrent.TimeoutException]withroot cause

java.util.concurrent.TimeoutException:null

解决方法

默认端口为：5672。它是在RABBITMQ_NODE_PORT变量中定义的。

Source: https://www.rabbitmq.com/configure.html#define-environment-variables

端口15672：用于访问RabbitMQ的管理控制台。

将属性文件中的端口从15672更改为5672，它将正常工作！
