<h3 dir="auto">Environment</h3>
<ul dir="auto">
<li>Dubbo version: 3.7.6</li>
<li>Operating System version: Mac os</li>
<li>Java version: java8<br>
nacos1.1.4</li>
</ul>
<h3 dir="auto">Steps to reproduce this issue</h3>
<ol dir="auto">
<li>同一个nacos下，配置了多个namespace</li>
<li>dubbo配置多注册中心后，项目启动后只注册到一个namespace下</li>
<li>另外一个namespace没有任何provider，配置如下<br>
dubbo:<br>
registries:<br>
test1:<br>
address: nacos://127.0.0.1:8848?namespace=3d064614-057d-4298-a6ce-34ed39e053e1<br>
test2:<br>
address: nacos://127.0.0.1:8848?namespace=1ca1de39-870c-497f-9ac2-f67bb3665691<br>
default: true</li>
</ol>
<p dir="auto">Pls. provide [GitHub address] to reproduce this issue.</p>
<h3 dir="auto">Expected Result</h3>
<p dir="auto">What do you expected from the above steps？<br>
希望能分别注册到2个namespace下。另外经过实验 当两个address配置的ip:port不一样时是可以成功注册到2个namespace下，是不是dubbo注册时认为ip+port一样就是相同的注册中心</p>

<p dir="auto">dubbo 2.7.5+nacos 1.1.4启动应用会在nacos配置列表中用服务命创建配置，一个服务会创建一个配置<br>

在nacos logs/config.log日志中发现发布配置的日志：<br>
INFO [main :config.NacosConfigService] [addr-hz-internal.edas.aliyun.com-c1d6921b-00bd-4f3f-b46e-3a44b407c036] [publish-single] ok, dataId=edas-provider, group=mapping-com.zfxf.app.dubbo.service.DemoService, tenant=c1d6921b-00bd-4f3f-b46e-3a44b407c036, config=1590738418788</p>
<p dir="auto">把dubbo 2.7.5降到2.7.3不会出现创建配置的问题，测试了2.7.6和2.7.5都会出现创建配置的情况。<br>
这个应该是个bug吧。</p>
