ibatis执行存储过程，java.lang.ArrayIndexOutOfBoundsException: 零

在项目开发中遇到一个问题，ibatis执行存储过程时报错

<procedure id="insertStatisticsResult_settle" parameterClass="String"> 

  <![CDATA[

     {call proc_stats_$statisticsType$()}

  ]]>

</procedure>

错误日志如下：

在网上查了资料没有有效的解决方案，所以只能跟踪日志来。

--- The error occurred while applying a parameter map.  
--- Check the insertStatisticsResult_settle-InlineParameterMap.

观察这个日志是由于传入参数错误，我看网上demo都是传入的map，而我的是string，

问题出在这，存储过程参数都以map的形式传入。

将传入参数改为hashmap就ok了

<procedure id="insertStatisticsResult_settle" parameterClass="java.util.HashMap"> 

  <![CDATA[

     {call proc_stats_$statisticsType$()}

</procedure>
