在hibernate中更新一些列值

String hql = "UPDATE 实体类名称 SET 列名 = :新值 WHERE 条件";
Query query = session.createQuery(hql);
query.setParameter("新值", 新值);
query.executeUpdate();

Session session = sessionFactory.openSession();
Transaction transaction = session.beginTransaction();

Criteria criteria = session.createCriteria(实体类名称.class)
    .add(Restrictions.eq("条件", 条件值));
criteria.setProjection(Projections.projectionList()
    .add(Projections.property("列名"), "新值"));
criteria.setResultTransformer(Transformers.aliasToBean(实体类名称.class));
List<实体类名称> entities = (List<实体类名称>) criteria.list();

for (实体类名称 entity : entities) {
    entity.set列名(新值);
    session.update(entity);
}

transaction.commit();
session.close();

String sql = "UPDATE 表名 SET 列名 = :新值 WHERE 条件";
Query query = session.createSQLQuery(sql);
query.setParameter("新值", 新值);
query.executeUpdate();
