2、报错描述：
接口：
http://localhost:28019/blog-api/v1/blog/list?pageNumber=1&pageSize=10
可以正常查询
http://localhost:28019/blog-api/v1/blog/list?pageNumber=1&pageSize=10&title=测试
多传了一个查询参数：title，报以上错误信息
3、数据库有title这个字段
4、修改，接受到title参数，查询时放到另一个字段里，例如title1
if (!StringUtils.isEmpty(title)) { params.put("title1", title); }
sql查询对应修改：
<where>
<if test="title1!=null and title1!=''">
and title like CONCAT('%',#{title1},'%')
</if>
</where>
5、原因分析：
