解决问题：Error creating bean with name 'xxxController': Unsatisfied dependency expressed through field 'xxxService'

问题

这个问题是因为bean在注入service的时候失败了，而service的实现类和mapper没有关联起来，mapper找不到

Error creating bean with name 'xxxController': Unsatisfied dependency expressed through field 'xxxService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'xxxServiceImpl': Unsatisfied dependency expressed through field 'baseMapper'

解决办法

在mapper接口上加一个注解@Mapper

@Mapper
public interface xxxProductMapper extends BaseMapper<SmmartProduct> {

}
