UserMapper.xml錯(cuò)誤代碼

        </collection>
    </resultMap>
    <select id="selectByUsername" resultMap="BaseMap">
        SELECT
            u.user_id,
            u.username,
            u.nickname,
            u.encrypted_password,
            u.phone,
            u.email,
            u.idd,
            u.gender,
            u.avatar,
            u.school,

            u.credentials_expired_time,

            u.user_type,
            u.we_chat_user_id,
            u.ali_pay_user_id
        FROM oauth_user u
        WHERE u.username = #{username}
    </select>

這樣查詢出來的User對(duì)象的admin和able字段為空。這是因?yàn)槲覀兊膕electByUsername 引用了我們定義的ResultMap。

注意看sql語句，其中有兩個(gè)字段我們?nèi)×藙e名

?? ?u.is_admin AS admin,
? ? ? ? u.is_able AS able,

也就是說，當(dāng)sql語句查詢出來的is_admin字段和is_able 字段已經(jīng)變?yōu)榱薬dmin字段和able字段，而ResultMap里面這兩個(gè)字段的映射：

? ?<result column="is_admin" property="admin" jdbcType="TINYINT"/>
? ? ? ? <result column="is_able" property="able" jdbcType="TINYINT"/>

當(dāng)ResultMap去映射字段信息的時(shí)候，發(fā)現(xiàn)找不到is_admin字段和is_able字段，因?yàn)樵趕ql語句我們已經(jīng)為這兩個(gè)字段去了別名，現(xiàn)在這兩個(gè)字段叫admin和able。所有ResultMap映射到實(shí)體類的時(shí)候，就會(huì)出現(xiàn)這兩個(gè)字段為空的情況。

正確寫法

去掉sql語句里面的別名，就可以咯。這樣resultMap就可以找到相應(yīng)的字段了。

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
