Having trouble implementing spring boot actuator custom health indicator

Question

I've tried to follow the documentation, but I only see "status : UP" every time I check. I even went as far as to return Health.down.build() universally, but I still just see "status : UP". I'm not sure what I've done wrong. I have no errors.

如果您将HealthIndicator注释添加到班级，则您的自定义@Component会随时随地注册。 如果您随后调用方法 actuator / health ，我想您将获得摘要状态：

{"status":"DOWN"}

只需将其添加到您的 application.properties 中，即可查看HealthIndicator结果的详细视图：

management.endpoint.health.show-details=always

，您将得到如下内容：

{
"status": "DOWN",
"details": {
    "MyCustomHealthCheck": {
        "status": "DOWN",
        "details": {
            "remote.system.down": "There is something wrong with system XXX"
        }
    },
    "diskSpace": {
        "status": "UP",
        "details": {
            "total": 499963174912,
            "free": 434322321408,
            "threshold": 10485760
        }
    }
}

}
