Unsatisfied dependency expressed through field 'XXXMapper'; nested exception is org.springframework.beans.factory

今天我在springboot整合mybatisPlus時遇到在service層 自動注入 Usermapper時遇到這個錯誤

，網上常見的幾個方法都試了，都不行

大家如果都試了不行可以試試我這個：

  1. 把mybatisPlus生成的文件全部刪除，目錄也刪除，重新生成

  2. 在啟動類中配置你生成的mapper所在的包@MapperScan(value = "com.bing.mapper")

這樣就把第一個錯誤解決了，然后買一送一

Database 出錯

很奇怪，我已經還原不出案發現場了

就是把 yaml中的數據庫url

和 generatorConfig.xml 中的調整一下

都設置成false
