我要返回mybatis自增主鍵id，添加了useGeneratedKeys="true" keyProperty="id" keyColumn="id"這三個屬性，但是感覺沒什么卵用。有誰用這種方式返回成功過的嗎？
說明：數(shù)據(jù)庫用的mysql。

代碼如下：
Mapper.xml

    <resultMap id="BaseResultMap" type="com.freedom.clothing.domain.Goods">
        <id column="id" jdbcType="INTEGER" property="id"/>
        <result column="url" jdbcType="VARCHAR" property="url"/>
        <result column="match_num" jdbcType="INTEGER" property="matchNum"/>
        <result column="is_del" jdbcType="BIT" property="isDel"/>
        <result column="group_id" jdbcType="INTEGER" property="groupId"/>
        <result column="source_id" jdbcType="INTEGER" property="sourceId"/>
        <result column="user_id" jdbcType="INTEGER" property="userId"/>
        <result column="create_time" jdbcType="TIMESTAMP" property="createTime"/>
        <result column="update_time" jdbcType="TIMESTAMP" property="updateTime"/>
    </resultMap>

    <insert id="insertSelective" parameterType="com.freedom.clothing.domain.Goods" useGeneratedKeys="true"
            keyProperty="id" keyColumn="id">
        insert into goods
