今天構建一個springboot 項目，采用mybatis+mysql 然后就出現了這種錯誤....浪費我半天時間

錯誤原因：是由於springboot 掃描不到 mapper

解決方案：

第一種：在mapper包下類配置@Mapper 注解

第二種：在springboot 啟動類上配置包掃描@ComponentScan()

第三種：在springboot 啟動類上配置Mapper掃描@MapperScan（注意：必須將路徑指定到 xxx.xxx.xxx.mapper 包為止，否則依舊掃描不到）多個mapper路徑可以以 @MapperScan（{mapper1路徑,mapper2路徑}）

這種本人親測

第四種解決方法，就是將 spring boot啟動類方法mapper上級，這樣也可以掃描到

工作中出了問題，解決時間太久，記錄一下
