Class JdbcRowHandler

java.lang.Object

com.nexacro.uiadapter17.spring.dao.jdbc.JdbcRowHandler

All Implemented Interfaces:

org.springframework.jdbc.core.RowCallbackHandler

public class JdbcRowHandler
extends Object
implements org.springframework.jdbc.core.RowCallbackHandler

jdbc를 사용하여 nexacro platform으로 대용량 데이터를 전송하려고 할때 사용되는 RowHandler 이다.

아래와 같은 형식으로 처리하며, 쿼리가 실행한 후 남아 있는 데이터가 존재할 수 있기 때문에 전송되지 않은 데이터를 전송한다.

DataSource dataSource = getDataSource();
Dbms dbms = dbmsProvider.getDbms(dataSource);

JdbcRowHandler rowHandler = new JdbcRowHandler(dbms, firstRowHandler, sendName, firstRowCount);
getJdbcTemplate().query(sql, args, callbackHandler);

// send remain data..
rowHandler.sendRemainData();
