如何存储单挑记录

Question

在servlet里面如何存储单挑记录
String id = request.getParameter("id");
DBconnection dbc = new DBconnection();
ResultSet rs = dbc.getResultSet("select * from db1 where id="+id);
try {
rs.last();
rs.getRow();
System.out.println(rs.getString("name"));
employee employee1 = new employee();
employee1.setName("name");
response.sendRedirect("editemployee.jsp");
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}在editemployee.jsp里面如何调用呢？

Answer 1

1. URL传值response.sendRedirect("editemployee.jsp?id=" + id);
editemployee.jsp中用String id = request.getParameter("id");取2.SESSION传值
session.setAttribute("id", id);
editemployee.jsp中用String id = (String)session.getAttribute("id");取

Answer 2

把对象存到session中，到jsp页面用el取
try {
rs.last();
rs.getRow();
System.out.println(rs.getString("name"));
employee employee1 = new employee();
employee1.setName("name");
request.getSession().setAttribute("employee", employee1 );
response.sendRedirect("editemployee.jsp");
} catch (SQLException e) {jsp页面：
${employee.name}
