测试spring cloud 使用consul注册服务的时候，出现critical，如下：

怎么解决这个问题，现在只能看到health check检查失败了。

受限调用这个请求Get http://consulIp:8500/v1/agent/checks，调完请求，就会拿到返回数据：

{
  ......
  "service:test-service-xx-xx-xx-xx": {
    "Node": "zookeeper-server1",
    "CheckID": "service:test-service-xx-xx-xx-xx",
    "Name": "Service 'test-service' check",
    "Status": "critical",
    "Notes": "",
    "Output": "HTTP GET http://xxx.xx.xxx.xxx:19008/actuator/health: 404 Output: <html><body><h1>Whitelabel Error Page</h1><p>This application has no explicit mapping for /error, so you are seeing this as a fallback.</p><div id='created'>Fri Mar 15 11:03:30 CST 2019</div><div>There was an unexpected error (type=Not Found, status=404).</div><div>No message available</div></body></html>",
    "ServiceID": "test-service-xx-xx-xx-xx",
    "ServiceName": "test-service",
    "ServiceTags": [
      "version=1.0",
      "secure=false"
    ],
    "Definition": {},
    "CreateIndex": 0,
    "ModifyIndex": 0
  }
  
  ........
}

就能看到consul调用http://xxx.xx.xxx.xxx:19008/actuator/health来检查servoce健康，却发现接口404，所以才会在页面出现错误。

我的测试环境是：

spring cloud Finch1ey.SR2
consul v1.4.3

bootstrap.yml配置是：

spring:
 cloud:
  consul:
   host: xxx.xxx.xxx.xxx
   port: 8500
   discovery:
    prefer-ip-address: true
    tags: version=1.0
    instance-id: ${spring.application.name}:${spring.cloud.client.ip-address}
    healthCheckInterval: 15s
    health-check-url: http://${spring.cloud.client.ip-address}:${server.port}/actuator/health

显然consul不能在这个服务上找到actuator/health接口，因为我用了actuator，所以service中应该配置了spring cloud actuator。

经过检查发现没有配置，所以actuator这个端点不能使用，加上这个包，问题就解决了。
