一个数据库很棘手的问题，高手请进

String sql = "select id,title,content,createdtime from blog where id="
+ id;

QueryRunner qr = new QueryRunner(ds);
List list =(List) qr.query(sql, new BeanListHandler<Blog>(Blog.class));

Blog blog = (Blog)list.get(0);

如果不用QueryRunner方法，单纯的写数据库代码，怎么放结果集放入List中 而且还是Blog.class类型

[解决办法]

Java code

 public TabCntvsOrder findObject(String ordernumber)        {            DbConnection dbcon = null;            Connection con=null;            PreparedStatement ps=null;            Statement st=null;            ResultSet rs=null;            ObjectClass oc= new ObjectClass();                try {                    dbcon = new DbConnection();                    con =dbcon.getCon();                    st = con.createStatement();                    String sql = "select * from TAB_CNTVSORDER where ORDERNUMBER='"+ordernumber+"'";                    rs = st.executeQuery(sql);                    while(rs.next()){//将循环拿出的结果放入对象中去                    oc.setId(rs.getInt(1));                                    }                                                     } catch (Exception e) {                    e.printStackTrace();                }                 finally {                    try {if (ps!=null) ps.close();}                    catch (Exception e) {}                    try {if (con!=null) con.close();}                    catch (Exception e) {}                             }                     return tco;//返回你设值的对象        }
