今天遇到了一些使用 Hibernate 执行查询的代码。该查询使用从表单提交的值。这让我很好奇这种代码是否“清理”了它的输入。
public List<School> search(String query) {
Session session = this.getCurrentSession();
query = "%" + query + "%";
Criteria criteria = session.createCriteria(getPersistentClass());
criteria.createAlias("country", "a");
Criterion nameCriterion = Restrictions.ilike("name", query);
Criterion cityCriterion = Restrictions.ilike("city", query);
Criterion countryCriterion = Restrictions.ilike("a.name", query);
Criterion criterion = Restrictions.or(Restrictions.or(nameCriterion, cityCriterion), countryCriterion);
criteria.add(criterion);
return criteria.list();
}
这安全吗?
