2.7.5-dubbo.metadata No effect

[yipixiaofeiyang]

Environment

• Dubbo version: 2.7.5
• Operating System version: win10 or centos7
• Java version: 1.8.0
• Zookeeper version: 3.5.6

Steps to reproduce this issue

My previous dubbo service version was 2.7.3. Today, I upgraded to 2.7.5. I found that the metadata can't be displayed all the time. The dubbo service registry in zookeeper, but zookeeper not /dubbo/metadata node path view. If I switch back to 2.7.3 and 2.7.4.1, it can be displayed. Are there any bugs? I need help~~

xml-config:
<dubbo:metadata-report address="zookeeper://192.168.11.100:2181?backup=192.168.11.105:2181" />

2.7.5变动较大，需要在parameter中增加新参数才行。
<dubbo:provider id="providerRpt" scope="remote" timeout="60000" token="false" registry="registryRpt"> <dubbo:parameter key="protocolIds" value="ptlDubbo"/> <!-- Dubbo-2.7.5 support --> <dubbo:parameter key="metadata" value="remote"/> <!-- 报表上报 --> <dubbo:service interface="xxx.xxx.ServiceRptService" ref="rmiRptService" /> </dubbo:provider>

<dubbo:parameter key="metadata" value="remote"/>

主要是这句

2.7.5 版本中dubbo.xsd中"metadata"标签改成了"metadata-type"，但是在服务和引用初始化的实际metadata上传获取元数据服务类型还是用的“metadata”，所以导致metadata没法上传，提交的PR修复了这个bug，在application中设置metadata-type为remote可以是metadata上传生效，记得要同时配置metadata-report，类似下面的示例
<dubbo:application name="demo-provider" metadata-type="remote"/>
<dubbo:metadata-report address="nacos://127.0.0.1:8848"/>

PS：对于上楼说的方法，也可以兼容
