This repo has been archived. All of the implements have been moved to [apache/dubbo](https://github.com/apache/dubbo). Please refer to https://github.com/apache/dubbo/tree/3.0/dubbo-spring-boot. All latest versions will be released with dubbo core.
dubbo-spring-boot-starter 3.0.4及一下，在多网卡的情况下会随机选择IP绑定端口，即使通过设置 ``` dubbo.provider.host = ${HOSTNAME} ``` 本质上还是会从底层随机选择IP绑定，这样即使在服务发现里面看上去是正常的，但是由于IP没绑定对，导致无法通讯。 建议： 多网卡的情况下，直接将端口绑定到0.0.0.0。

我使用的是springboot2.1.15对应dubbo0.2.0，其中使用了外部的配置文件@PropertySource("file:D:/opt/config/taskcenter/a.properties")，占位符${},发现dubbo加载的时候不会把占位符转换为我要的参数,如何是好？

在使用Dubbo整合Nacos的时候发现生产者启动一直都没问题，但是消费者这块启动的时候一直报错，竟然是找到我 Dao 和 Service，但是这种报错不应该属于Spring里的吗，我使用@DubboReference好像没有引用到服务实例，具体是什么原因呢？
