下面给大家介绍下mybatis结果生成键值对的实例代码，具体内容如下所示：

在实际应用中我们经常会遇到这样的情况，需要给下拉框赋值，这个时候就需要键值对了，具体使用方法如下
1，在maper.xml文件中定义结果类型(resultType)定义为hashmap,如下所示
2，在对应的mapper类中用List>来接受这个类型，如下所示
public List> selectSuperUnitInfo();
其实最强大的莫过于resultMap类型了，这个可以在mapper.xml文件中自定义扩展类型，然后在包中添加这个类型即可，真是强大
下面给大家补充下MyBatis返回Map键值对数据
List> getMtypeList();

]返回的结果带有大写与小写的key
如果在sql语句中的列名使用大写会怎样呢？自己测试一下吧！如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对创新互联网站的支持！
