  解决了,应该是a_name = #{aName} and a_password = #{aPassword} and a_enable = 1

  难道是我的xml配置错了?

  <mapper namespace="org.approval.dao.AccountDao">
     <!--目的: 为DAO接口方法提供SQL-->
  
  
     <select id="queryByName" parameterType="Account" resultType="Account">
         select
           a_id,a_name,a_password,a_grade,a_enable
         from
           account
         where
           a_name = #{account.aName} and a_password = #{account.aPassword} and a_enable = 1
     </select>
  

  </mapper>
