I have a spring boot microservice: Zuul-api-gateway-server, and I am trying to implement a Zipkin server listening to rabbitmq for logging messages within the microservice.

I have added the following dependencies to this microservice:

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-sleuth-zipkin</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.amqp</groupId>
        <artifactId>spring-rabbit</artifactId>
    </dependency>

I have started the Zipkin server using the following commands:

SET RABBIT_URI=amqp://localhost java -jar zipkin.jar

I then try to start up the microservice however I get the following error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'rabbitListenerContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/amqp/RabbitAnnotationDrivenConfiguration.class]: Initialization of bean failed; nested exception is java.lang.NullPointerException at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:584) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:498) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.beans.factory.support.AbstractBeanFactory.lambda$doGetBean$0(AbstractBeanFactory.java:320) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:222) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:318) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:199) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:846) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:863) ~[spring-context-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:546) ~[spring-context-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.refresh(ServletWebServerApplicationContext.java:142) ~[spring-boot-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:775) [spring-boot-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:397) [spring-boot-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.SpringApplication.run(SpringApplication.java:316) [spring-boot-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.SpringApplication.run(SpringApplication.java:1260) [spring-boot-2.1.1.RELEASE.jar:2.1.1.RELEASE] at org.springframework.boot.SpringApplication.run(SpringApplication.java:1248) [spring-boot-2.1.1.RELEASE.jar:2.1.1.RELEASE] at com.shopping.sandbox.netflixzuulapigatewayserver.NetflixZuulApiGatewayServerApplication.main(NetflixZuulApiGatewayServerApplication.java:16) [classes/:na] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_171] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[na:1.8.0_171] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_171] at java.lang.reflect.Method.invoke(Method.java:498) ~[na:1.8.0_171] at org.springframework.boot.devtools.restart.RestartLauncher.run(RestartLauncher.java:49) [spring-boot-devtools-2.1.1.RELEASE.jar:2.1.1.RELEASE] Caused by: java.lang.NullPointerException: null at org.springframework.amqp.rabbit.config.AbstractRabbitListenerContainerFactory.getAdviceChain(AbstractRabbitListenerContainerFactory.java:198) ~[spring-rabbit-2.1.2.RELEASE.jar:2.1.2.RELEASE] at brave.spring.rabbit.SpringRabbitTracing.decorateSimpleRabbitListenerContainerFactory(SpringRabbitTracing.java:170) ~[brave-instrumentation-spring-rabbit-5.4.4.jar:na] at org.springframework.cloud.sleuth.instrument.messaging.SleuthRabbitBeanPostProcessor.postProcessBeforeInitialization(TraceMessagingAutoConfiguration.java:186) ~[spring-cloud-sleuth-core-2.1.0.M2.jar:2.1.0.M2] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsBeforeInitialization(AbstractAutowireCapableBeanFactory.java:419) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1737) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:576) ~[spring-beans-5.1.3.RELEASE.jar:5.1.3.RELEASE] ... 20 common frames omitted

Did you copy paste your pom entries correctly? The correct artifactId for Sleuth Zipkin is spring-cloud-starter-zipkin - Brian Devins-Suresh

As there is a bug in Spring AMQP, which will be fixed in Release 2.1.3 Issue link

For a tempory fix, you can enable retry properties to create advice chain.

spring.rabbitmq.listener.direct.retry.enabled=true
spring.rabbitmq.listener.simple.retry.enabled=true

Hope this resolves your problem.

I had this same issue, changing Spring Boot version to 2.1.0.RELEASE did the trick for me. You should try it too. There must be something wrong with RabbitMQ in Spring Boot version 2.1.1.RELEASE.
