7.3.5. 搜索
要执行搜索,请使用 Lucene API 或 Hibernate Search query DSL 创建 Lucene 查询查询。将查询嵌套在 org.hibernate.Query 中,以从 Hibernate API 获取所需的功能。以下代码根据索引字段准备查询。执行代码将返回 Books 列表。
示例:使用 Hibernate 搜索会话创建和执行搜索
FullTextSession fullTextSession = Search.getFullTextSession(session); Transaction tx = fullTextSession.beginTransaction(); // create native Lucene query using the query DSL // alternatively you can write the Lucene query using the Lucene query parser // or the Lucene programmatic API. The Hibernate Search DSL is recommended though QueryBuilder qb = fullTextSession.getSearchFactory() .buildQueryBuilder().forEntity( Book.class ).get(); org.apache.lucene.search.Query query = qb .keyword() .onFields("title", "subtitle", "authors.name", "publicationDate") .matching("Java rocks!") .createQuery(); // wrap Lucene query in a org.hibernate.Query org.hibernate.Query hibQuery = fullTextSession.createFullTextQuery(query, Book.class); // execute search List result = hibQuery.list(); tx.commit(); session.close();
FullTextSession fullTextSession = Search.getFullTextSession(session);
Transaction tx = fullTextSession.beginTransaction();
// create native Lucene query using the query DSL
// alternatively you can write the Lucene query using the Lucene query parser
// or the Lucene programmatic API. The Hibernate Search DSL is recommended though
QueryBuilder qb = fullTextSession.getSearchFactory()
.buildQueryBuilder().forEntity( Book.class ).get();
org.apache.lucene.search.Query query = qb
.keyword()
.onFields("title", "subtitle", "authors.name", "publicationDate")
.matching("Java rocks!")
.createQuery();
// wrap Lucene query in a org.hibernate.Query
org.hibernate.Query hibQuery =
fullTextSession.createFullTextQuery(query, Book.class);
// execute search
List result = hibQuery.list();
tx.commit();
session.close();
示例:使用 Jakarta Persistence 创建和执行搜索
EntityManager em = entityManagerFactory.createEntityManager(); FullTextEntityManager fullTextEntityManager = org.hibernate.search.jpa.Search.getFullTextEntityManager(em); em.getTransaction().begin(); // create native Lucene query using the query DSL // alternatively you can write the Lucene query using the Lucene query parser // or the Lucene programmatic API. The Hibernate Search DSL is recommended though QueryBuilder qb = fullTextEntityManager.getSearchFactory() .buildQueryBuilder().forEntity( Book.class ).get(); org.apache.lucene.search.Query query = qb .keyword() .onFields("title", "subtitle", "authors.name", "publicationDate") .matching("Java rocks!") .createQuery(); // wrap Lucene query in a javax.persistence.Query javax.persistence.Query persistenceQuery = fullTextEntityManager.createFullTextQuery(query, Book.class); // execute search List result = persistenceQuery.getResultList(); em.getTransaction().commit(); em.close();
EntityManager em = entityManagerFactory.createEntityManager();
FullTextEntityManager fullTextEntityManager =
org.hibernate.search.jpa.Search.getFullTextEntityManager(em);
em.getTransaction().begin();
// create native Lucene query using the query DSL
// alternatively you can write the Lucene query using the Lucene query parser
// or the Lucene programmatic API. The Hibernate Search DSL is recommended though
QueryBuilder qb = fullTextEntityManager.getSearchFactory()
.buildQueryBuilder().forEntity( Book.class ).get();
org.apache.lucene.search.Query query = qb
.keyword()
.onFields("title", "subtitle", "authors.name", "publicationDate")
.matching("Java rocks!")
.createQuery();
// wrap Lucene query in a javax.persistence.Query
javax.persistence.Query persistenceQuery =
fullTextEntityManager.createFullTextQuery(query, Book.class);
// execute search
List result = persistenceQuery.getResultList();
em.getTransaction().commit();
em.close();
