"message":"divide:Can not find selector, please check your configuration!" #4662

Question

你好，我使用的是目前master分支的代码进行编译测试运行，我按照一篇博客的方法ShenYu快速开始，进行的快速配置，但是在最后一步验证网关是否成功时出现了问题： 请求接口：http://localhost:9195/dubbo/demo/findAll 相应内容：{"code":-107,"message":"divide:Can not find selector, please check your configuration!"} 同时在bootstrap模块的日志中显示错误： 2023-05-23 22:57:12 [shenyu-netty-nio-2] ERROR org.apache.shenyu.plugin.api.utils.WebFluxResultUtils - can not match selector data: divide 我查看了Issue中相关的提问，没有找到合适的解决方法，可以解答一下吗

make sure dubbo plugin enabled and dubbo plugin selector and rule must match /dubbo/demo/findAll

HeiXXwowoTou commented 1 year ago

我确认我已经启用dubbo插件以及启用了dubbo选择器和/dubbo/demo/findAll的规则，昨天我也不太清楚为什么会出现 divide:Can not find selector，今天我在调试时出现了 {"code": -102,"message": "dubbo:Rule not found!"}提示，我经过debug调试后发现可能是，我在admin模块在运行时，重新运行了数据库初始化的脚本，或许是admin模块没有重启，导致获取的选择器在库中没有找到，我重启了admin模块之后这个问题也解决了。 目前我也不太清楚出现divide:Can not find selector的原因 以及如何复现

firstly, start shenyu admin, and start shenyu-bootstrap and service.
