spring cloud consul注册的服务有报错 critical

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

怎么解决这个问题，现在只能看到health check检查失败了。

首先调用这个请求Get [http://consulIp:8500/v1/agent/checks，调完请求，就会拿到返回数据：][http_consulIp_8500_v1_agent_checks]

{
        ......
        "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。
