今天调试程序是遇到了，下面的一个问题。我将对应的SQL语句拿到Toad下也能正常的执行，感觉有点莫名其妙，根据异常信息的提示查看对应的映射结果集也没发现错误，然后百度了一下，也有许多朋友也遇到过这样的问题，原因大概有两个，一是：结果集中的字段含有对应的数据库产品的关键字，二是：在xml文件中的SQL语句中，两个填充变量间没有写逗号，我仔细分析自己的SQL语句，觉得有可能是第二种原因！where 1 = 1 order by ? ?占位符的方式传递参数是确实没有逗号，我将SQL语句中order by #{sortName} #{sortOrder} 改写为<![CDATA[order by ${sortName} ${sortOrder} ]]>这种方式其他不变，问题就解决了！
在这里想说一下在对应的与数据库交互的XML文件中用#和$传递参数的特点
#是以占位符的形式来传递对应变量的参数值的，框架会对传入的参数做预编译的动作，用$时会将传入的变量的参数值原样的传递过去
