java - 如何在 Hibernate 中使用 Contains

Question

session = sessionFactory.openSession();         
Transaction tx = session.beginTransaction();
String hql ="from CustomObjectId where CONTAINS(fileName,fileName)";
Query query = session.createQuery(hql);
query.setParameter("fileName", fileName);
List file=query.list();
tx.commit();

如何搜索CONTAINS？

Answer 1

您需要使用 IN 子句，如下所示:

 session = sessionFactory.openSession();         
String hql =" from CustomObjectId c where c.fileName in :fileName";
Query query = session.createQuery(hql);
query.setParameter("fileName", fileName);
List file=query.list();

此外，您不需要(显式)事务来仅从数据库读取。所以，只需删除 Transaction tx = session.beginTransaction(); and tx.commit();行。
