问题如题，提前做了sentinel控制台的推模式集成nacos，客户端也配置了nacos动态数据源，但是看日志规则没拉下来，日志中发现是去接口拉规则的时候没有tenant参数导致找不到配置文件(因为我的控制台把规则推送到了指定命名空间下，不是公共命名空间)。

跟踪代码发现，sringcloudalibaba是通过注入NacosDataSourceFactoryBean类的实例来拉规则的，这个类里面的属性就对应的是nacos动态数据源的配置属性，里面有一个属性namespace，把这个配置值加上，数据源就可以正确拉取配置了，例子如下：

spring:
  cloud: # cloud
    sentinel:
      transport:
        port: 8719 # Sentinel 控制台添加了一个限流规则，会把规则数据 push 给这个端口的 Http Server 接收
        dashboard: 192.168.20.134:8100
      datasource:
        flow:
          nacos:
            server-addr: 192.168.20.133:8848
            dataId: ${spring.application.name}-flow-rules
            groupId: SENTINEL_GROUP
            namespace: xxx   #就是它
            data-type: json
            rule-type: flow

NacosDataSourceFactoryBean类如下：
