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.
at org.mybatis.spring.MyBatisExceptionTranslator.translateExceptionIfPossible(MyBatisExceptionTranslator.java:76) ~[mybatis-spring-1.2.3.jar:1.2.3]
at org.mybatis.spring.SqlSessionTemplate$SqlSessionInterceptor.invoke(SqlSessionTemplate.java:399) ~[mybatis-spring-1.2.3.jar:1.2.3]

at org.mybatis.spring.SqlSessionTemplate.selectList(SqlSessionTemplate.java:205) ~[mybatis-spring-1.2.3.jar:1.2.3]………………

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">

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。
