正在做一个登录的程序，请教各位大侠们

有一个User保存着用户信息，然后是Message进行判断，如果存在那么返回一个User，大概是下面的代码：

google_ad_width = 250; google_ad_height = 250; google_ad_format = "250x250_as"; google_color_url = "000000";

public User get(String name, String psw) {

........

rs=stmt.executeQuery("select * from table where name=""+name+"" and psw=""+psw+"" ");

User user1=null;

if(rs.next()){

user1=new User();

user1.setName(name);

user1.setPassword(rs.getString("pwd"));

user1.setBirth(rs.getString("birth"));

user1.setEmail(rs.getString("email"));

user1.setSex(rs.getString("sex"));

user1.setTname(rs.getString("tname"));

user1.setPower(rs.getString("power"));

return user1;

}

return user1

..........

}

然后是一个servlet，关键代码如下：

String name=request.getParameter("name");

String psw=request.getParameter("psw");
