div中显示jsp从后台获取的数据的方法：
1首先是取值：
<%
class.forname("com.mysql.jdbc.driver").newinstance();
connection connection = drivermanager.getconnection(url);
statement statement = connection.createstatement();
string sql = "select * from " + tablename;
resultset rs = statement.executequery(sql);
%>
2然后是输出
<%
out.print("学号");
%>
3最后是显示
<%
out.print("学号");
%>
