    <where>
        <if test="vo.score!=null and vo.score !=''">
            <if test="vo.score == 2">
                and 1=1
            </if>
            and shop_score=#{vo.score}
        </if>
        <if test="vo.reply!=null and vo.reply != '' ">
            <choose>
                <when test="vo.reply = '1' ">
                    and apply = '1'
                </when>
                <when test="vo.reply = '2' ">
                    and apply = '0'
                </when>
            </choose>
        </if>
        <if test="vo.content != null and vo.content != '' ">
            <choose>
                <when test="vo.content = '1' ">
                    and evaluate_img is not null
                </when>
                <when test="vo.content = '2' ">
                    and evaluate_img is null
                </when>
            </choose>
        </if>
        <if test="vo.month!=null and vo.month !=''">
            and date_format (create_time,'%Y-%m-%d') between date_format (#{vo.firstDay},'%Y-%m-%d') and
            date_format (#{vo.lastDay},'%Y-%m-%d')
        </if>
    </where>
</select>

在查询时，当我reply或content传值为1时，sql正常运行，当传值为2时，拼接出来的sql出现问题，仍然是传值为1时的sql

Answer 1

test里面的表达式要用==，你只用了一个=
