第一种方法:
因为这个是xml格式的,所以不允许出现类似“>”这样的字符,但是都可以使用<![CDATA[ ]]>符号进行说明,将此类符号不进行解析 。 mapper文件示例代码:
<select id="selectMonthAdvertise" resultMap="ResultMap">
select * from ad_n_advertise_t where user_id in
<foreach item="item" index="index" collection="userIdList" open="(" separator="," close=")">
#{item}
</foreach>
and isdelete=#{isdelete,jdbcType=TINYINT}
and <![CDATA[</span>date_sub(curdate(), INTERVAL 30 DAY) <= date(crt_time)]]>
order by crt_time desc
</select>
第二种方法:
用了转义字符把>和<替换掉。 mapper文件示例代码:
<select id="selectMonthAdvertise" resultMap="ResultMap">
select * from ad_n_advertise_t where user_id in
<foreach item="item" index="index" collection="userIdList" open="(" separator="," close=")">
#{item}
</foreach>
and isdelete=#{isdelete,jdbcType=TINYINT}
and date_sub(curdate(), INTERVAL 30 DAY) <= date(crt_time)
order by crt_time desc
</select>附:转义字符表。
| < | < | 小于号 |
| > | > | 大于号 |
| & | & | 和 |
| ' | ‘ | 单引号 |
