xml内容

解决思路

为parameterType设置别名或者补全路径

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}
    
        and friend_type = {friendType}
    
    
        and friend_status = {friendStatus}
