[a1767028198]

第一个 把启动类SpringbootApplciation注解里面的exclude里面全部删掉 第二个 Mapper接口加载@Mapper注解 再试试

引用 楼主 weixin_54243103 的回复:

试试在RegisterMapper 接口上面加注解@Repository 还有就是要学会贴代码。

[KeepSayingNo]

问问题的方式要改进下，贴了一大堆图

[日渐消瘦的小宋]

换一个maven仓库，重新下载一下依赖

[Francis.Sun]

idea的mapper注入那里是红的，也就是没有注入到容器里，所以那个mapper你要加上@Mapper。

[你才是秃头]

启动项上 exclude 中有个DataSource.........class的 ..这是sprinboot不配置数据库防止报错用的..你这个应该是配置了数据库的吧(不然你这查询查毛线) .还有就是第三张图..你都用限制了post才能访问controller ....但是你里面还有个限制了get的方法..

[你才是秃头]

去这 https://blog.csdn.net/qq_38701478/article/details/88808628 你好像有个自动注入也有问题

[明白畅达]

RigisterMapper加上@Mapper注解即可
