解決問題：Error creating bean with name 'xxxController': Unsatisfied dependency expressed through field 'xxxService'

問題

這個問題是因為bean在注入service的時候失敗了，而service的實現類和mapper沒有關聯起來，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'

解決辦法

在mapper接口上加一個注解@Mapper

@Mapper
public interface xxxProductMapper extends BaseMapper<SmmartProduct> {

}
