mybatis报错:A query was run and no Result Maps were found for the Mapped Statement

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:ID" parameterType="java.util.Map" resultType="java.util.Map">


最后总结下,就是mybatis中的所有查询,都必须返回resultType或者resultMap的值,否则就会报如上错误的。
