Could not autowire. No beans of ‘XxxxxMapper‘ type found.

1.問題描述

我們在寫springboot專案常常會見IDEA報錯Could not autowire. No beans of ‘XxxxxMapper’ type found.但是專案依然可以執行。

在這裡插入圖片描述

2.原因分析

spring中@controller，@service，@Repository,@component被Spring掃描並注入到容器中，其中@component是其他三個的元註解。

@Repository在持久層
@Service在服務層
@Controller在控制層中

3.問題解決

兩個方法：
第一種：直接在持久層介面加上註解@Repository

第二種：不用加註解，

spring配置檔案中配置了MapperScannerConfigurer這個bean，它會掃描持久層介面建立實現類並交給spring管理。
介面上使用了@Mapper註解或者springboot中主類上使用了@MapperScan註解，和MapperScannerConfigurer作用一樣。

但是第二種方案還是會爆紅可以降低Autowired檢測的級別
具體操作步驟可以參考：csdn連結地址

解決Could not autowire. No beans of ‘xxxx‘ type found問題

遇到Could not autowire. No beans of ‘xxxx’ type found的錯誤提示在Idea的spring工程裡，經常會遇到Could not autowire. No beans of ‘xxxx’ type found的錯誤提示。但程式的編譯和執行都是沒有問題

springboot 報錯 Could not autowire. No beans of 'XXX' type found.

在idea開發專案時候，自動裝載的時候報錯Could not autowire. No beans of ‘DebtProdService’ type found.

解決：Could not autowire. No beans of 'XXXXXXXXXX' type found.

針對於不能夠正常編譯執行的解決方案：正確的匯入包，如果是檢查錯誤提示中的類的包是否匯入正確，這種錯誤最常見在mybatis中的mapper下，比如對於mybatis的的註解版或配置檔案版的解決辦法：
