Cause: org.apache.ibatis.executor.ExecutorException: A query was run and no Result Maps were found for the Mapped Statement 'com.shadow.foretaste.UserInfoDao.getPhoneNum'. It's likely that neither a Result Type nor a Result Map was specified.
導致這個錯誤的原因是:
mapper.xml中沒有指定返回值類型
<select id="getPhoneNum" >
select phone_num from user_info where id = #{id}
</select>修改后:
<select id="getPhoneNum" resultType="String">
select phone_num from user_info where id = #{id}
