今天编辑mybatis的xml文件，出现如下错误：
程序出现异常[A query was run and no Result Maps were found for the Mapped Statement '***'. It's likely that neither a Result Type nor a Result Map was specified.

仔细查看mybatis的配置文件，发现遗漏一个属性：resultType
报错的配置是：<select id="ID" parameterType="java.util.Map">
正确的配置应该是<select id="ID" parameterType="java.util.Map" resultType="java.util.Map">
