使用
@Inject
protected Dao dao;
后报如下错误信息:

用shardingjdbc 吗?? 还是普通的jdbc

@wendal 我能说我不知道该做啥配置吗?应该只要jdbc就行,不知道需要在哪里配置例如MySQLURL、用户名、密码啥的

这里有demo哦 https://github.com/nutzam/nutzboot/tree/dev/nutzboot-demo/nutzboot-demo-simple

如果你加入了shardingjdbc ,那就自动走分库分表了

是用 https://get.nutz.io 生成的吗?? 选了shardingjdbc ?

@wendal 谢谢,这回复速度好感人啊!
对的,选择了shardingjdbc了,剔除掉相关配置就不报错了!
