This function has been removed in Dubbo 2.7, please select other registry for migration.
The Simple registry itself is an ordinary Dubbo service, which can reduce third-party dependencies and make the overall communication method consistent.
Expose the Simple registry as a Dubbo service:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- Expose service configuration -->
<dubbo:service interface="org.apache.dubbo.registry.RegistryService" ref="registryService" registry="N/A" ondisconnect="disconnect" callbacks="1000">
<dubbo:method name="subscribe"><dubbo:argument index="1" callback="true" /></dubbo:method>
<dubbo:method name="unsubscribe"><dubbo:argument index="1" callback="false" /></dubbo:method>
</dubbo:service>
<!-- Implementation of a simple registration center, which can be expanded by itself to achieve cluster and state synchronization -->
<bean id="registryService" class="org.apache.dubbo.registry.simple.SimpleRegistryService" />
</beans>
Quoting the Simple Registry service:
<dubbo:registry address="127.0.0.1:9090" />
or:
<dubbo:service interface="org.apache.dubbo.registry.RegistryService" group="simple" version="1.0.0" ... >
or:
<dubbo:registry address="127.0.0.1:9090" group="simple" version="1.0.0" />
This SimpleRegistryService is just a simple implementation and does not support clustering. It can be used as a reference for a custom registry, but it is not suitable for direct use in a production environment.
