执行executeBatch批处理遇到的问题

执行Batch批处理遇到的问题

1.务必关掉自动提交

增强执行效率

conn.setAutoCommit(false);

2.executeBatch失效问题

<1>务必将语句pstmt = conn.prepareStatement(sql);放到循环体外，否则只能插入一条语句

		int size = ipAdressList.size();
		try {
			conn = JdbcUtil.getConnection();
			conn.setAutoCommit(false);
			pstmt = conn.prepareStatement(sql);
			for (int i = 0; i < size; i++) {
			//	pstmt = conn.prepareStatement(sql);只能插入最后一条
				ipAd = ipAdressList.get(i);
				int index = 1;
				pstmt.setObject(index++, ipAd.getadress());
				pstmt.setObject(index++, ipAd.getPort());
				pstmt.setObject(index++, ipAd.getSpeed());
				pstmt.setObject(index++, ipAd.getCountry());
				pstmt.setObject(index++, ipAd.getProvince());
				pstmt.setObject(index++, ipAd.getCity());
				pstmt.setObject(index++, ipAd.getIsp());
				pstmt.setObject(index++, ipAd.isDomestic());
				pstmt.setObject(index++, ipAd.isAlive());
				pstmt.addBatch();
			}
			pstmt.executeBatch();
			conn.commit();
		} catch (Exception e) {
			e.printStackTrace();
		}finally {
			JdbcUtil.close(rs, stmt, pstmt, conn);
		}

<2>务必最后提交

conn.commit();
