How to use the same bean defined in multiple applicationContext.xml files?

I have two Spring projects: a client and server application. I would like to create a third integration test project. However my tests fail with:

Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'meterRegistry' defined in class path resource [applicationContext.xml]: Cannot register bean definition [Generic bean: class [io.micrometer.core.instrument.logging.LoggingMeterRegistry]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null; defined in class path resource [applicationContext.xml]] for bean 'meterRegistry': There is already [Generic bean: class [io.micrometer.core.instrument.logging.LoggingMeterRegistry]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null; defined in class path resource [applicationContext.xml]] bound.

Each of the applications defines their own (identical) meterRegistry bean in their respective applicationContext.xml files.

Is there any way of telling Spring that both applications can share the meterRegistry bean?

I would up adding an application.properties file to the integration test project that contained:

spring.main.allow-bean-definition-overriding=true

You have to use <import> field in the applicationContext.xml :

How to use ?

For example :

applicationContextClient.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans 
                           http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id = "example" class="com.test.Example"/>

</beans>

applicationContextServer.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.springframework.org/schema/beans 
                               http://www.springframework.org/schema/beans/spring-beans.xsd">

         <import resource="applicationContextClient.xml" />

         <bean id="Example2" class="com.test.Example2">
           <property name="example" ref="example"/>
         </bean> 

</beans>
