No MyBatis mapper was found in '[com.taiji]' package. Please check your configuration.

回答: 这个问题的原因是在指定的包路径下没有找到MyBatis的Mapper接口。根据引用\[1\]中的报错日志，可以看到警告信息" No MyBatis mapper was found in '\[com.taiji\]' package. Please check your configuration."。解决这个问题的方法是在项目内的某个路径下建立一个接口，并在接口上添加@Mapper注解。需要注意的是，这个接口不能在@MapperScan注解定义的basePackage路径下，否则会出现另外一个新的警告"Skipping MapperFactoryBean with name xx Bean already defined with the same name!"。这是因为在启动时，Spring Boot的默认basePackage会被MyBatis-Plus的自动配置拿来作为基目录去扫描是否有带有@Mapper注解的接口需要注册到Spring容器中。如果没有这个注解，则会报错。同时，如果@Mapper注解定义的接口在@MapperScan注解定义的路径下，会导致重复扫描创建bean的问题。因此，需要确保这两个注解不在同一个路径下。\[1\]\[3\]
