解決思路

爲parameterType設置別名或者補全路徑

<!-- 查詢某個好友-->
<select id="findFriend" parameterType="com.example.antchat.entity.AssociationInfo" resultMap="associationInfo">
    select user_id,friend_id,friend_remark,friend_type,friend_status,create_time,update_time from associationinfo where user_id = #{userId} and friend_id = #{friendId}
    <if test="friendType!=null and friendType!=''">
        and friend_type = {friendType}
    </if>
    <if test="friendStatus!=null and friendStatus!=''">
        and friend_status = {friendStatus}
    </if>
</select>
