no available service ‘null‘ found, please make sure registry config correct 看

最近在研究seata，发现seata jpa工程里springboot2.0.0 Release，想升级到springboot2.2

但是发现一个问题

no available service 'null' found, please make sure registry config correct

看了好久，很多原因是

file.config 文件
vgroupMapping.storage-service = "default"

application.properties 文件

spring.cloud.alibaba.seata.tx-service-group="storage-service"

很多网上都说忘了配置，其实这个版本springboot2.0已经跑通了，一直报这个错误肯定不是这个原因

于是就开始找找

报错信息如下

2020-12-19 22:20:33.311 ERROR [storage-service,,,] 11584 --- [imeoutChecker_1] i.s.c.r.netty.NettyClientChannelManager  : no available service 'null' found, please make sure registry config correct

于是网上看 Could not found property service.vgroup_mapping."storage-service", try to use default value instead.

但是配置文件是

vgroupMapping.storage-service

vgroup_mapping ？？？vgroupMapping.storage-service

不知道什么时候vgroupMapping 改成vgroup_mapping

于是按错误推理

vgroup_mapping.storage-service = "default"  改成这样的，就可以了
