今天爱分享给大家带来o.s.b.a.amqp.RabbitHealthIndicator:Rabbit health check failed【解决方法】，希望能够帮助到大家。
学习 Spring Cloud Stream 的时候用到 RabbitMQ，连接本地的 RabbitMQ 一切正常，连接远程的 RabbitMQ 始终会报 Rabbit health check failed.
问题描述
错误提示是这样的:

解决思路
首先来看我的项目的 yml 配置文件：
server:
port: 8801
spring:
application:
name: cloud-stream-provider
cloud:
stream:
binders: # 在此处配置要绑定的rabbitmq的服务信息；
defaultRabbit: # 表示定义的名称，用于于binding整合
type: rabbit # 消息组件类型
environment: # 设置rabbitmq的相关的环境配置
spring:
rabbitmq:
host: rabbitmq
port: 5672
username: guest
password: guest
virtual-host: /
bindings: # 服务的整合处理
output: # 这个名字是一个通道的名称
destination: studyExchange # 表示要使用的Exchange名称定义
content-type: application/json # 设置消息类型，本次为json，文本则设置“text/plain”
binder: defaultRabbit # 设置要绑定的消息服务的具体设置
eureka:
client: # 客户端进行Eureka注册的配置
service-url:
defaultZone: http://localhost:7001/eureka
instance:
lease-renewal-interval-in-seconds: 2 # 设置心跳的时间间隔（默认是30秒）
lease-expiration-duration-in-seconds: 5 # 如果现在超过了5秒的间隔（默认是90秒）
instance-id: send-8801.com # 在信息列表时显示主机名称
prefer-ip-address: true # 访问的路径变为IP地址
看似没有任何问题，但有几项参数并没有在 yml 中配置：
spring:
rabbitmq:
host: rabbitmq
port: 5672
username: guest
password: guest
如果上述参数没有配置，默认会尝试连接 localhost:5672，就会造成 Rabbit health check failed。配置了上述参数后的 yml 配置文件如下：
server:
port: 8801
spring:
application:
name: cloud-stream-provider
cloud:
stream:
binders: # 在此处配置要绑定的rabbitmq的服务信息；
defaultRabbit: # 表示定义的名称，用于于binding整合
type: rabbit # 消息组件类型
environment: # 设置rabbitmq的相关的环境配置
spring:
rabbitmq:
host: rabbitmq
port: 5672
username: guest
password: guest
virtual-host: /
bindings: # 服务的整合处理
output: # 这个名字是一个通道的名称
destination: studyExchange # 表示要使用的Exchange名称定义
content-type: application/json # 设置消息类型，本次为json，文本则设置“text/plain”
binder: defaultRabbit # 设置要绑定的消息服务的具体设置
#如果连接到远程RabbitMQ报Rabbit health check failed异常
#配置以下信息
#因为默认会尝试连接localhost:5672
rabbitmq:
host: rabbitmq
port: 5672
username: guest
password: guest
eureka:
client: # 客户端进行Eureka注册的配置
service-url:
defaultZone: http://localhost:7001/eureka
instance:
lease-renewal-interval-in-seconds: 2 # 设置心跳的时间间隔（默认是30秒）
lease-expiration-duration-in-seconds: 5 # 如果现在超过了5秒的间隔（默认是90秒）
instance-id: send-8801.com # 在信息列表时显示主机名称
prefer-ip-address: true # 访问的路径变为IP地址
再次运行项目，问题成功解决，Rabbit health check failed 没有出现。
