5. Solrj API사용법

 

Solrj API 를 사용하기 위해서는 미리 관련 라이브러리가 추가되어 있어야 한다.

(‘1.5 라이브러리 추가’ 부분 참조.)

 

 

5.1 데이터 인덱싱

 

5.1.1 Sample Code

 

//CommonsHttpSolrServer객체 생성

CommonsHttpSolrServer server = null;   

       

        String url = "http://localhost:8080/solr/";

        server = new CommonsHttpSolrServer( url );

 

        //인덱싱 할 데이터

List<OasisDocument> docs = oasisService.getAllDocument();

 

OasisDocument doc = new OasisDocument();

 

doc.setDocId(10000)

doc.setTitle(“what is Solr?”);

doc.setContent(“Solr is an open source enterprise search server based on the Lucene.”)

 

 

//데이터 추가

        server.addBeans(docs);

             server.addBean(doc);

            

        //서버 객체 커밋 (인덱싱)

             server.commit();

 

 

5.2 데이터 검색

 

5.2.1 Sample Code

 

String url = http://localhost:8080/solr/;

CommonsHttpSolrServer server = new CommonsHttpSolrServer( url );

       

SolrQuery query = new SolrQuery();

query.setQuery(“title” + “:” + “solr”);//검색어 셋팅

query.addSortField("docId", SolrQuery.ORDER.asc );//정렬 방식

query.setStart(startNum);//시작 번호(시작번호부터 설정된 개수만큼 가져옴)

 

 

QueryResponse rsp = server.query( query );//검색을 요청하고 응답 저장

 

//검색 결과 가져오기

SolrDocumentList docs = rsp.getResults();

List<BlogLog> docs2 = rsp.getBeans(BlogLog.class);
