Package com.easydesk.lucene.config

Class LuceneConfig

java.lang.Object

com.easydesk.lucene.config.LuceneConfig

@Configuration
@EnableScheduling
public class LuceneConfig
extends Object

Lucene module 을 구성한다. Application 의 @Configuration 에서 @Import(LuceneConfig.class) 로 사용한다.

기존 Avalon component 설정 (componentConfiguration.xml 의 <lucene>) 은 아래 property 로 대체된다.

 easydesk.lucene.index-location=lucene          # <indexLocation> (상대 경로는 working directory 기준)
 easydesk.lucene.analyzer=com.easydesk.lucene.analyzer.CJKAnalyzer   # <analyzer>
 easydesk.lucene.commit-period=60000            # <sleepPeriod> : 주기적인 commit 간격 (msec)
 easydesk.lucene.ram-buffer-size-mb=16
 easydesk.lucene.recreate-incompatible-index=false   # Lucene 4.x index 를 지우고 새로 만들지
 easydesk.lucene.slow-search-threshold=50       # 이 시간(msec) 이상 걸린 검색은 WARN log
 

<version> 설정은 Lucene 10 에서 Analyzer 가 Version 을 받지 않으므로 없어졌다.

주기적인 commit 을 위해 EnableScheduling 을 포함한다.
