Brixton.M4 + zuul: Expected single matching bean but found 2: dropwizardMetricServices,servoMetricServices

Question

I am trying to upgrade a Spring Boot + Spring Cloud based project to Brixton.M4 due to zuul's lack of support for PATCH (https://github.com/spring-cloud/spring-cloud-netflix/issues/412) in the version packaged with SC's Brixton.M3. I have the spring-boot-starter-actuator and spring-cloud-starter-zuul enabled amongst others but now the container fails to start with the following error:

No qualifying bean of type [org.springframework.boot.actuate.metrics.CounterService] is defined:
expected single matching bean but found 2: dropwizardMetricServices,servoMetricServices

More stacktrace:

There are indeed two CounterService typed beans in the classpath: DropwizardMetricServices packed in the spring-boot-actuator-1.3.1.RELEASE.jar and ServoMetricServices located in spring-cloud-netflix-core-1.1.0.M4.jar

Is there any way to disable one of those? I checked the documentation but I couldn't find any obvious way.

Thanks!

Answer 1

Small fix to the above answer

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

Answer 2

you can use @Primary for it in your java configuration file like this:

@Bean
@Primary
public DropwizardMetricServices dropwizardMetricServices(){
    return new DropwizardMetricServices();
}
