如果返回List，resultType=”String”就可以了，如果需要返回List

 <select id="selectAllInnerUser" resultType="String">
    select account_name
    from user_account
    where is_deleted=0 and user_type=0
  </select>

2.

 <resultMap id="stringsResult" type="java.lang.String">
    <result column="account_name"
 
 property="accountName" jdbcType="VARCHAR" />
  </resultMap>
  <select id="selectAllInnerUser" resultMap="stringsResult">
    select account_name
    from user_account
    where is_deleted=0 and user_type=0
  </select>

二、要返回map可以通過如下方式知道key和value

<resultMap type="HashMap" id="testMap"
 
>  
    <result column="UA_INFO" property="key" />  
    <association property="value" resultMap="com.xxx.xxx.BaseResultMap"></association>  
  </resultMap>  
  <select id="getUaMapByTimestamp" parameterType="Map" resultMap="testMap">
  </select> 

下面的還未嘗試！
或者List

<select id="getMyCredit"  parameterClass="java.util.Map" resultClass="java.util.HashMap">
</select>

這樣設定返回型別為resultClass=”java.util.HashMap”，查詢時執行queryForList
List
