同事让我帮他找一个错误,他说明明写的对的,怎么老是报错。其实,使用MyBaties在编写sql配置文件时,都会遇到的一个小问题,问题虽小,对初学者可能都会碰到。

    从异常的提示发现是配置文件中,find这个方法的sql参数类型或者名称写错了,但是你发现这个位置并没有些写错。于是你很困惑,其实问题就在这个配置文件中,提示的也对,只是位置不对。mybaties中只要有任何一个地方报错,都无法通过。最后发现是另个一个方法上将parameterType写成了parameterMap了(

  1. <select id="getClassByID" parameterMap="String" resultMap="classResultMap">  

)。

再者之所以大家犯错,有一个原因是在编写配置文件时,会提示parameterMap ,但是这个在mybaties中已经不再用这个属性了。所以大家写配置文件时,要小心细心。
