@Timed not working on a spring application (not a webapp)

[bhuvanalakshmi]

I am using Java annotation to configure.

@Configuration
@EnableMetrics
public class MetricsConfig extends MetricsConfigurerAdapter{

    @Bean
    public MetricRegistry metricRegistry(){
        return new MetricRegistry();
    }

    @Override
    public void configureReporters(MetricRegistry metricRegistry) {

        metricRegistry.registerAll(new GarbageCollectorMetricSet());
        metricRegistry.registerAll(new MemoryUsageGaugeSet());
        metricRegistry.registerAll(new ThreadStatesGaugeSet());

        // registerReporter allows the MetricsConfigurerAdapter to
        // shut down the reporter when the Spring context is closed
        registerReporter(ConsoleReporter
                .forRegistry(metricRegistry)
                .build())
        .start(1, TimeUnit.MINUTES);

    }

}

JVM metrics are reported in the console. But when i use @Timed annotation on another class. I am getting Bean Creation exception and application won't start. When the @Timed annotation is removed, application starts and JVM metrics are reported in the console. Is there an issue with configuration ?

Change @EnableMetrics to @EnableMetrics(proxyTargetClass = true)

[ryantenney]

Your SampleDataMgmt bean likely implements an interface, and somewhere else you're referencing the class, not the interface. By default Spring AOP uses Java Dynamic Proxies when proxying a class which implements an interface, so instead of an instance of SampleDataMgmt: class SampleDataMgmt implements SomeInterface { … } Spring will have "generated" a class class Proxy$47 implements SomeInterface { … }. Proxy Target Class will force that proxy to be class Proxy$47 extends SampleDataMgm { … }

Hope that helps.

Thank you, that helped.
