mybatis中sql拼接问题

代码：Integer offerCount = collegeStudentOfferMapper.selectCount(new QueryWrapper().lambda()
.eq(CollegeStudentOffer::getIsDeleted,0).last("AND " + sqlConfig));

其中sqlConfig为：   "本科" IN ("本科", "硕士研究生", "博士研究生") AND ("金融学" LIKE "%金融%" OR "金融学" LIKE "%经济%" OR "金融学" LIKE "%财务%")

运行报错：java.sql.SQLException: sql injection violation, double const condition : SELECT COUNT(1) FROM college_student_offer WHERE (is_deleted = ?) AND "本科" IN ("本科", "硕士研究生", "博士研究生") AND ("金融学" LIKE "%金融%" OR "金融学" LIKE "%经济%" OR "金融学" LIKE "%财务%")

你这个数据库字段怎么设置的呀，怎么能用中文呢？要是公司工作，看你设计表示中文的估计gg了。
看你的sql，

SELECT COUNT(1) FROM college_student_offer WHERE (is_deleted = ?) AND "本科" IN ("本科", "硕士研究生", "博士研究生") AND ("金融学" LIKE "%金融%" OR "金融学" LIKE "%经济%" OR "金融学" LIKE "%财务%")

"本科" IN ("本科", "硕士研究生", "博士研究生") --这里“本科”是字段，为什么要加双引号？
你的错就是字段加了双引号。
