ibatis遍历数组出错

ibatis遍历数组对象时，填写不全，容易报错。以下情况就经常遇到问题。

     <isNotNull property="typeList" prepend=" AND ">
            <iterate property="typeList" conjunction="OR" open="(" close=")">
                type = #typeList[]#
            iterate>
        isNotNull>

如上，遍历对象时，必须把上面信息写全面，如果发生遗漏，容易报错。
情况1：

<isNotNull property="typeList" prepend=" AND ">
    <iterate conjunction="OR" open="(" close=")">
        type = #typeList[]#
    iterate>
isNotNull>

如果iterate中不写明对象名称，必然要进行报错。如下：

--- Cause: com.ibatis.sqlmap.client.SqlMapException: ParameterObject or property was not a Collection, Array or Iterator.; nested exception is com.ibatis.common.jdbc.exception.NestedSQLException: 
--- The error occurred in ibatis/sqlmap/user.xml. 
--- The error occurred while preparing the mapped statement for execution. 
--- Check the StockRunLog.getStockRunLogListCount. 
--- Check the parameter map. 
--- Cause: com.ibatis.sqlmap.client.SqlMapException: ParameterObject or property was not a Collection, Array or Iterator.
org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation; uncategorized SQLException for SQL []; SQL state [null]; error code [0];   

根据错误，还是很好识别的。
情况2：

<isNotNull property="typeList" >
    <iterate property="typeList" conjunction="OR" open="(" close=")">
        type = #typeList[]#
    iterate>
isNotNull>

当缺少apend时，造成上个字段和遍历字段无连接词，会报错。如下：

--- The error occurred while applying a parameter map.  
--- Check the StockRunLog.getStockRunLogListCountMap.  
--- Check the statement (query failed).  
--- Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '( type = 10 OR type = 11 ' at line 1]; SQL was [] for task [SqlMapClient operation]

--- The error occurred while applying a parameter map.  
--- Check the StockRunLog.getStockRunLogListMap.  
--- Check the statement (query failed).  

此时，必须要加上对应的apend才行。
情况3：
有时候，代码都是完全正确的，但是也会报错。如下：

Error getting ordinal list from JavaBean.
Cause java.lang.NumberFormatException: For input string: ""

对于这种情况，还没找到原因，根据报错信息，一直没找到错误哪里。代码都正确。无奈，重新编译了一次，倒是成功了。不过，以下内容，可以做个参考。

后续再看看此情况的原因好了。
