在jsp中获取数据库数据

<%
Class.forName("com.mysql.jdbc.Driver");//加载mysql驱动
Connection conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/test1", "root", "3701211994812sls");//localhost是本机地址，3306是端口号，最后是用户名和密码
Statement stmt=conn.createStatement();//实例化Statement对象
String queryNumberSQL="SELECT * from p_user where username=‘"+name+"‘ and password=‘"+password+"‘";
ResultSet rs=stmt.executeQuery(queryNumberSQL);//执行数据库查询操作并获取结果集
boolean flag=false;//初始化flag
if(rs.next()){//判断结果
flag=true;
session.setAttribute("UserName", name);//将name的内容赋值给UserName
}else{
flag=false;
}
