本文介绍了在使用MyBatis进行练习时遇到的Cannot resolve method 'getResourceAsStream'错误。问题源于IntelliJ IDEA自动导入的包错误。通过将错误的import语句改为import org.apache.ibatis.io.Resources，成功解决了问题，确保了MyBatis的正常运行。

今天在写一个mybatis的练习时，出现了一个Cannot resolve method ‘getResourceAsStream’ in 'Resources’错误，如下图

检查了maven等jar包依赖没有问题，后经查原因是idea自动导包时导的包有错误
自动导包如下图，为错误导包

改为import org.apache.ibatis.io.Resources;错误解决了

解决办法：下图中的两个都需要勾选，代码会自动导入很多包（不勾选自己导包的会找不到）#别人出错顶多出一个，我出错是把别人出过的错都出一遍#

cannot resolve method getResourceAsStream 按部就班完成初始创建，但是这个getResourceAsStream一直报红没有任何提示。 解决方法： import org.apache.ibatis.io.Resources; 在最上方导入这个包。 会出现这样的问题，意思是上面的包已经包含了下面这个包，只要把上面导入注释掉/删除掉就可以了。 问题虽然解决，但是只是一种方法，不适用所有情况，也不知道到底是什么原因，有大神看到，求解答。 ...
