Hibernate Criteria API 中的 SQL 'LIKE' 运算符

java sql-like criteria hibernate hibernate-criteria
2022-09-03 17:09:42

我想用Hibernate实现一些通用过滤器。它应该像SQL中的运算符一样工作：CriteriaLIKE

SELECT * FROM table WHERE table.ANYCOLOUMNHERE LIKE '%'||anyvaluehere||'%'

我有其中键是列名，值是它的值。Map<String, String>

我尝试了这样的东西：

for (Entry<String, String> filter : filters.entrySet()) {
    crit.add(Restrictions.ilike(filter.getKey(), filter.getValue(), MatchMode.ANYWHERE));
}

但是当字段类型不是 String 时，它会导致：java.lang.ClassCastException

有没有办法解决这个问题？


答案 1

您可以使用 like（） 限制条件，如下所示：

session = sessionFactory.openSession();
Criteria query = session.createCriteria(Pojo.class);
query.add(Restrictions.like("anycolumn", "anyvalue", MatchMode.START));

它将为您提供以“anyvalue”开头的字符串列表。


答案 2

您也可以在休眠会话不存在时使用分离标准。

DetachedCriteria criteria = DetachedCriteria.forClass(Pojo.class);
criteria.add(Restrictions.like("column", value, MatchMode.ANYWHERE));

它将与列字符串中任意位置的值匹配。您可以使用不同类型的模式。

参考页面： https://docs.jboss.org/hibernate/orm/3.2/api/org/hibernate/criterion/MatchMode.html

分离标准：

- 当休眠会话不存在时，分离标准是非常好的替代条件。

使用分离标准与条件完全相同，只是您可以在没有访问会话的情况下执行查询的初始创建和设置。在运行查询时，必须使用 将其转换为可执行查询。getExecutableCriteria(session)

如果要构建复杂的查询（可能通过多步骤过程），这将非常有用，因为您不需要访问所有位置的会话。运行查询时，只需在最后一步使用会话。

在引擎盖下，DetachedCriteria使用CruitalImpl，如果您调用，它将与您获得的类相同。session.createCriteria()
