Class LazyMetricsRecorder

java.lang.Object

com.fayupable.logged.spring.metrics.LazyMetricsRecorder

All Implemented Interfaces:

MetricsRecorder

public class LazyMetricsRecorder
extends Object
implements MetricsRecorder

MetricsRecorder that defers the choice between a real Micrometer-backed recorder and a no-op fallback to the first actual invocation, instead of to Spring Boot auto-configuration ordering.

Whether a MeterRegistry bean exists at a given point during context refresh depends on the order in which Spring Boot processes auto-configurations, an order this module cannot reliably pin itself against across Spring Boot versions. Resolving lazily through ObjectProvider, on the other hand, is unaffected by that ordering: by the time any @Logged method is actually invoked, the application context has fully started, and any MeterRegistry bean that is ever going to exist already does.
