intellig idea 使用@Resource或者@Autowire报错，出现红色波浪线；在确定不是代码出错的问题下，
可以隐藏这个提示
报错提示：
Could not autowire. No beans of 'UserDAO' type found。(Ctrl+F1) Checks autowiring problems in a bean class.
@Mapper //使用Mapper注解方式，开启扫描
public interface UserDAO {
String TABLE_NAME = "user";

解决办法：
Settings - Editor - Inspections - Spring - Spring Core - Code - Autowiring for Bean Class 勾去掉
