之前我们的有两个Application Module，一个是Sys_Web, 负责提供基础的功能和服务，比如：机构注册、供应商管理、编码规则管理，并提供相关服务给其他应用。 另外一个是Biz_Web，用来给供应提供业务操作的管理，要调用基础管理的服务。
之前采用的Zookeeper + Dubbo 访问，运行稳定。我们想迁移到Nacos 环境，用Nacos的配置服务和注册服务，于是采用SpringBoot + Nacos + AlibabaDubbo。

** Sys_Web Dubbo Config:**
dubbo.application.name=sys_web_dubbo
#dubbo.application.qos-enable=false
dubbo.protocol.port=20880
dubbo.protocol.name=dubbo
dubbo.registry.address=nacos://127.0.0.1:8848

dubbo.consumer.id=mcoms-consumer
dubbo.consumer.default=true
dubbo.consumer.timeout=8000
dubbo.consumer.retries=0
dubbo.consumer.check=false
Biz_Web Dubbo Config:
dubbo.application.name=biz_web_dubbo
#dubbo.application.qos-enable=false
dubbo.protocol.port=20881
dubbo.protocol.name=dubbo
dubbo.registry.address=nacos://127.0.0.1:8848

dubbo.consumer.id=mcoms-consumer1
dubbo.consumer.default=true
dubbo.consumer.timeout=8000
dubbo.consumer.retries=0
dubbo.consumer.check=false
Sys_web 服务提供代码
@DubboService(interfaceClass = IBasSupplierService.class)
@Component
public class BasSupplierServiceImpl extends BaseService<BasSupplier, BasSupplierMapper> implements IBasSupplierService {
public int supplierMapping(String userAccount, SupplierMappingVO param) {
}
}
Biz_web 服务消费代码：
@DubboService(interfaceClass = IBizHosDeliveryService.class)
@Component
public class BizHosDeliveryServiceImpl extends BaseService<BizHosDelivery, BizHosDeliveryMapper> implements IBizHosDeliveryService {
@DubboReference(interfaceClass = IBasSupplierService.class)
IBasSupplierService supplierService;
@DubboReference(interfaceClass = IBizHosDeliverydetailService.class)
IBizHosDeliverydetailService deliverydetailService;
@DubboReference(check=false)
IBizHosOrderRespService orderRespService;
}
当Sys_web 和Biz_web 应用单独启动，能正常启动，并能访问不交叉访问的服务；
当启动一个后，启动另外一个用，新启动的应用就暂停在那里。

我不知道是SpringBoot 与Alibaba Dubbo版本的问题还是？
现在还不知道怎么个思路，还请指点。
