내 프로젝트에서 매우 기본적인 최대 절전 모드 검색을 구현했습니다. 다음은 검색 방법입니다.java.nio.channels.OverlappingFileLockException 최대 절전 모드 검색
public List<Patients> search (String givenName, String middleName, String email, String phoneNumber)
throws InterruptedException, AppException {
fullTextEntityManager = Search.getFullTextEntityManager(EntityManagerUtil.getEntityManager());
fullTextEntityManager.createIndexer().startAndWait();
QueryBuilder qb = fullTextEntityManager
.getSearchFactory()
.buildQueryBuilder()
.forEntity(Patients.class)
.overridesForField("givenName", "customanalyzer_query")
.overridesForField("middleName", "customanalyzer_query")
.overridesForField("email", "customanalyzer_query")
.overridesForField("phoneNumber", "customanalyzer_query")
.get();
org.apache.lucene.search.Query luceneQuery = qb.bool()
.must(qb.keyword().wildcard().onField("givenName").matching(givenName).createQuery())
.must(qb.keyword().wildcard().onField("middleName").matching(middleName).createQuery())
.must(qb.keyword().wildcard().onField("email").matching(email).createQuery())
.must(qb.keyword().wildcard().onField("phoneNumber").matching(phoneNumber).createQuery()).createQuery();
javax.persistence.Query jpaQuery =
fullTextEntityManager.createFullTextQuery(luceneQuery, Patients.class);
@SuppressWarnings("unchecked")
List<Patients> result = jpaQuery.getResultList();
return result;
}
데이터를 읽으려면 Postgresql을 사용하고 있습니다.
처음 실행하면 모든 것이 잘됩니다. 색인이 디렉토리에 작성되면 검색이 완료됩니다.
그런 다음 데이터베이스에 몇 가지 항목을 추가합니다. 추가 한 후에 동일한 검색을 실행합니다. 때로는 원하는 결과를 얻고 때로는 새로 추가 된 항목이 검색에 포함되지 않습니다. 그리고 나는이 예외가 :
