Spring Boot自定义健康指示灯未显示

Question

我相信几乎所有的教程都在互联网上，读了很多这样的答案，但我仍然卡住了。

@Component
public class HealthCheck implements HealthIndicator {

    @Override
    public Health health() {
        return Health.up().build();
    }

}

management.endpoints.web.exposure.include: "*"
management.endpoint.health.show-details: ALWAYS

    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-web'

id 'org.springframework.boot' version '2.2.0.RELEASE'

@SpringBootApplication
public class PaymentServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(PaymentServiceApplication.class, args);
    }

}

{
    "status": "UP",
    "components": {
        "diskSpace": {
            "status": "UP",
            "details": {
                "total": 250685575168,
                "free": 99168997376,
                "threshold": 10485760
            }
        },
        "ping": {
            "status": "UP"
        }
    }
}

Answer 1

我找到了解决办法，但不确定原因。这个类确实没有注册为bean，令人惊讶的是，显式添加base packages属性有所帮助：

java prettyprint-override">@SpringBootApplication(scanBasePackages="com.example.*")

有趣的是，没有必要在不同的项目中做上述工作。
