在properties里面配置多个
dubbo.registry.address=xxxxxx
dubbo.registry.aaa.address=xxxxxx
在xml里面配置
<dubbo:reference id="xx" interface="xxxx" version="1.0.0" registry="aaa"/>
就会报错 Too much registries found
实际上配置的dubbo.registry.aaa.address=xxxxxx 并不能根据aaa来匹配

org.apache.dubbo.config.AbstractInterfaceConfig.convertRegistryIdsToRegistries()
if (((List)tmpRegistries).size() > ids.length) {
                throw new IllegalStateException("Too much registries found, the registries assigned to this service are :" + this.registryIds + ", but got " + ((List)tmpRegistries).size() + " registries!");
            }
是不是应该需要在 tmpRegistries 里面根据 id 取对应的 Registries
