Spring configuration of local service

local.xml:

<bean id=“xxxService” class=“com.xxx.XxxServiceImpl” />
<bean id=“xxxAction” class=“com.xxx.XxxAction”>
    <property name=“xxxService” ref=“xxxService” />
</bean>

Spring configuration of remote service

The remote configuration can be done by very little change based on the local configuration:

  • split the local.xml into two part, put the service define part into remote-privider.xml(exists in the provider node), meanwhile the refrence part into remote-consumer.xml(exists in the consumer node).
  • add <dubbo:service> to the provider’s configuration, and <dubbo:reference> to the consumer’s configuration.

remote-provider.xml:

<!-- define remote service bean the same way as local service bean -->
<bean id=“xxxService” class=“com.xxx.XxxServiceImpl” /> 
<!-- expose the remote service -->
<dubbo:service interface=“com.xxx.XxxService” ref=“xxxService” />

remote-consumer.xml:

<!-- reference the remote service -->
<dubbo:reference id=“xxxService” interface=“com.xxx.XxxService” />
<!-- use remote service the same say as local service -->
<bean id=“xxxAction” class=“com.xxx.XxxAction”> 
    <property name=“xxxService” ref=“xxxService” />
</bean>
