项目经验：jdbc实现批量添加、批量删除

jdbc批量添加：

	/**
	 * 批量save专家意见list
	 */
	public void saveBatchZjyjList(List zjyjList) {
		Connection conn = null;
		PreparedStatement ps = null;
		try {
			Session session = template.getSessionFactory().getCurrentSession();
			conn = session.connection();
			String sql = "insert into ZX_D_ZJYJ(uuid,hsbm,zjmc,ssdw,zc,lxfs,zjyj,cjsj) values (?,?,?,?,?,?,?,?)";
			ps = conn.prepareStatement(sql);
			for (ZxDZjyj zjyj:zjyjList) {
				ps.setString(1, generateUuid());
				ps.setString(2, zjyj.getHsbm());
				ps.setString(3, zjyj.getZjmc());
				ps.setString(4, zjyj.getSsdw());
				ps.setString(5, zjyj.getZc());
				ps.setString(6, zjyj.getLxfs());
				ps.setString(7, zjyj.getZjyj());
				ps.setTimestamp(8, Timestamp.valueOf(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(zjyj.getCjsj())));
				ps.addBatch();   

			}
			ps.executeBatch();
		} catch (SQLException ex) {
			ex.printStackTrace();
		} finally{
			if (ps != null) {
				try {
					ps.close();
				} catch (SQLException e) {
					e.printStackTrace();
				}
			}
			if(conn != null){
				try {
					conn.close();
				} catch (SQLException e) {
					e.printStackTrace();
				}
			}
		}
	}

 

jdbc批量删除：

/**
	 * 批量delete专家意见list
	 */
	public void delBatchZjyjList(ZxDHsjl hsjl) {
		Connection conn = null;
		PreparedStatement ps = null;
		try {
			Session session = template.getSessionFactory().getCurrentSession();
			conn = session.connection();
			String sql = "delete from ZX_D_ZJYJ where hsbm=?";
			ps = conn.prepareStatement(sql);
			ps.setString(1, hsjl.getUuid());
			ps.addBatch();  

			ps.executeBatch();
		} catch (SQLException ex) {
			ex.printStackTrace();
		} finally{
			if(ps != null){
				try {
					ps.close();
				} catch (SQLException e) {
					e.printStackTrace();
				}
			}
			if(conn !=null){
				try {
					conn.close();
				} catch (SQLException e) {
					e.printStackTrace();
				}
			}
		}
