解决方案：

1. 方案一：
   这种错误是服务层代码没有成功注册到注册中心导致，请检查一下你的服务层代码是否添加了@service注解，并且该注解的包一定是com.alibaba.dubbo.config.annotation包，不是org.springframework.stereotype.Service，这个地方容易出错。
2. 方案二：
   检查分布式服务提供者和消费者的 .yml 文件中的注册中心地址是否正确

dubbo:
  registry:
    address: zookeeper://127.0.0.1:2181  #zookeeper注册中心地址

3. 方案三：
   检查调用的接口路径是否错误，在参数中 interface=com.len.pdms.service.TenantService，而com.len.pdms.service.TenantService就是要远程调用的接口，检查远程或第三发服务提供商（也就是提供者）接口包路径是否与消费者一致（必须保证一致）。
4. 方案四：
   如果以上问题都没有的话，那么很有可能是你的分布式服务提供者没有开启，只是打开了消费者服务。也就是说我们在运行的时候需要同时开启两个Application服务。第一次玩这个没有注意 ╥﹏╥
