Java中将ResultSet结果集转换为List

1、【方法1】借助bean的办法

//rs是一个查询语句所返回的结果集

ResultSet rs=new ResultSet();

rs=pstmt.executeQuery();

//将rs逐条取出，并将每一项放在一个bean对应的值里

               while(rs.next())

               { 

                 RecBean rec=new RecBean();

                 rec.setId(rs.getInt(1));

                 rec.setAgentNo(rs.getString(2));

                rec.setFileName(rs.getString(3));

                list.add(rec);

                }

2、【方法2】借助ResultSetMetaData 和Map

private static List convertList(ResultSet rs) throws SQLException {

        List list = new ArrayList();

        ResultSetMetaData md = rs.getMetaData();

        int columnCount = md.getColumnCount();

        while (rs.next()) {

            Map rowData = new HashMap();

            for (int i = 1; i <= columnCount; i++) {

                rowData.put(md.getColumnName(i), rs.getObject(i));

            }

            list.add(rowData);

        }

        return list;

}
