<h3 dir="auto">Reason</h3>
<p dir="auto">The low version of dubbo does not provide elegant closure of the dubbo service network, so we are compatible with reflection, but now we don't know the number of consumers.</p>
<p dir="auto">i can get provider bu using reflect,but can't get consumer. Thanks in advance. please<br>
forgive my lame English</p>
