Mybatis Plus 调用Oracle存储 返回索引 Cursor

什么要写这篇博客

mybatis 调用oracle 存储过程，返回一个表。这样的景场用得比较少，我用了mybatis这么长时间，还第一次这么用。
尝试过程也是比较痛苦，网上资料少不说，很多配置拿下来，也是跑不起来。。最后自己不停地跟据mybatis抛出来的错误，调整代码，终于跑起来了。做一下笔记。

存储过程

存储过程比较长，只需要关注输入，输出参数就可以了。

</mapper>

这里主要注意
1：输入参数的格式为 #{misType,mode=IN,jdbcType=VARCHAR}，需要设参数名称（misType），参数类型 （mode=IN)，参数数据类型（jdbcType=VARCHAR）为字符,网上找的资料都是没有设置 jdbcType=VARCHAR，但我的环境跑不起来。
2：输出参数设置， #{result,mode=OUT,jdbcType=CURSOR, javaType=ResultSet,resultMap=misPrcInputResult。名称（result），参数类型为输出（mode=OUT），参数数据类型（jdbcType=CURSOR）为索引。
输出的参数还需要另外设置javaType和resultMap。javaType=ResultSet 表示对应的java类型是一个列表，对应List；resultMap=misPrcInputResult 表示集合字段对应的印身是 misPrcInputResult。

接口跟Service层就不贴代码了。。
