一、背景

健康检测接口返回OUT_OF_SERVICE

curl -X GET http://192.168.5.53:8085/mgm/health

{"status":"OUT_OF_SERVICE"}

从日志启动看，没有任何报错信息；而且jvm进程也启动成功。

关键的一点信息是，服务的swagger地址访问也正常。

但是，consul上的服务状态就是不健康。
spring boot 服务健康检测返回OUT_OF_SERVICE，导致服务无法成功注册到consul,java-consul,spring boot,consul

当然，重启大法不好使。

二、解决办法

增加配置项： management.endpoint.health.show-details: always
