springcloud整合consul遇到的问题

服务可以在consul看到但是一直红叉显示All service checks failing

consul 控制台一直提示

2024-04-07T19:36:19.680+0800 [WARN]  agent.http: This request used the token query parameter which is deprecated and will be removed in a future Consul version: logUrl="/v1/catalog/services?wait=2s&index=19&token=<hidden>"

排查思路

一开始看控制台的WARN，看到有token的字眼还以为要配置token,尝试配置了token还是不行，后来看了程序的日志发现打印了一条日志

2024-04-07T19:47:11.812+08:00  INFO 20956 --- [           main] o.s.c.c.s.ConsulServiceRegistry          : Registering service with consul: NewService{id='consumer-8002', name='consumer', tags=[], address='localhost', meta={secure=false}, port=8002, enableTagOverride=null, check=Check{script='null', dockerContainerID='null', shell='null', interval='10s', ttl='null', http='http://localhost:8002/actuator/health', method='null', header={}, tcp='null', timeout='null', deregisterCriticalServiceAfter='null', tlsSkipVerify=null, status='null', grpc='null', grpcUseTLS=null}, checks=null}

里面的check{http=‘http://localhost:8002/actuator/health’} 一你了我的注意，/actuator/health这个很熟悉是spring-boot-starter-actuator的一个健康检查接口

解决

①引入spring-boot-starter-actuator 服务注册上去后consul会检查这个接口来判断服务是否存活
②如果不想引入spring-boot-starter-actuator可以自己自定义一个接口，然后再配置文件配置健康检查的路径就行

spring:
  application:
    name: consumer
  cloud:
    consul:
      host: localhost
      port: 8500
      discovery:
      	# 配置健康检查路径 默认是/actuator/health
        health-check-path: /actuator/health
