目的

上文提到仅使用discovery包自带的注册功能进行服务注册，但是由于监控的是 /health，使用actuator实现自由度不够，并且有些低级异常可能不完全影响服务运行，但状态依然为DOWN，导致过于监测过于严格。

可用方案

解决这个问题有两种方案：

• 自己实现health类似的接口，并且在spring.cloud.consul.discovery.health-check-path配置为自己实现的接口；
• 通过consul配置文件的方式进行注册，并且把spring.cloud.consul.discovery.register设置为false不自动进行注册；

本文说明第二种方式。

实施

配置环境同上一篇文章： 定义consul的服务配置，配置如下（为了简单就做HTTP监测，实际上可以使用脚本进行健康监测更为灵活）：

{"services": [{"name": "spring-boot-consul-service", "port": 17003, "checks": [{"interval": "10s", "http": "http://192.168.0.185:17003/service/hi", "timeout": "1s"}], "enable_tag_override": false, "address": "192.168.0.185", "id": "spring-boot-consul-service"}]
}

启动consul和spring-boot-consul-service服务后，可以看到服务已经正常注册上去

然后调用接口（ http://192.168.0.184:8500/v1/catalog/service/spring-boot-consul-service ） 查看服务状态，显示如下，可以看到三个服务都已经注册了

[{"ID": "e88608f3-93d0-cfac-e0fe-8ffc2c1cdef0", "Node": "agent-4", "Address": "192.168.0.184", "Datacenter": "dc1", "TaggedAddresses": {"lan": "192.168.0.184", "wan": "192.168.0.184"}, "NodeMeta": {"consul-network-segment": ""}, "ServiceID": "spring-boot-consul-service", "ServiceName": "spring-boot-consul-service", "ServiceTags": [ ], "ServiceAddress": "192.168.0.184", "ServicePort": 17003, "ServiceEnableTagOverride": false, "CreateIndex": 881, "ModifyIndex": 881}, {"ID": "d6337397-b7e2-8cc7-11ef-ff36d9c1a65e", "Node": "agent-5", "Address": "192.168.0.185", "Datacenter": "dc1", "TaggedAddresses": {"lan": "192.168.0.185", "wan": "192.168.0.185"}, "NodeMeta": {"consul-network-segment": ""}, "ServiceID": "spring-boot-consul-service", "ServiceName": "spring-boot-consul-service", "ServiceTags": [ ], "ServiceAddress": "192.168.0.185", "ServicePort": 17003, "ServiceEnableTagOverride": false, "CreateIndex": 885, "ModifyIndex": 885}, {"ID": "b40a3dc6-b735-d733-33f5-5369368870e6", "Node": "agent-6", "Address": "192.168.0.186", "Datacenter": "dc1", "TaggedAddresses": {"lan": "192.168.0.186", "wan": "192.168.0.186"}, "NodeMeta": {"consul-network-segment": ""}, "ServiceID": "spring-boot-consul-service", "ServiceName": "spring-boot-consul-service", "ServiceTags": [ ], "ServiceAddress": "192.168.0.186", "ServicePort": 17003, "ServiceEnableTagOverride": false, "CreateIndex": 887, "ModifyIndex": 887}
]

本地启动spring-boot-consul-client服务，访问service接口，结果如下： http://127.0.0.1:17004/service/add?a=1&b=2

/add, host:192.168.0.108, service_id:application-17004; result : 3; port:17004-------------/add, host:192.168.0.184, service_id:application-17003; result : 3; port:17003/add, host:192.168.0.108, service_id:application-17004; result : 3; port:17004-------------/add, host:192.168.0.185, service_id:application-17003; result : 3; port:17003/add, host:192.168.0.108, service_id:application-17004; result : 3; port:17004-------------/add, host:192.168.0.186, service_id:application-17003; result : 3; port:17003
