为何jsp页面注册成功仍显示错误提示[已结贴,结贴人:btboys]

发表于：2007-05-21 22:29:50 楼主

注册成功后仍显示:
"注册时出现错误，请稍后再试 "
reg.jsp源码如下:

<%@ page session= "true " %>
<jsp:usebean id= "user " scope= "page " class= "goodsshop.run.op_user " />
<%
string mesg = " ";
string submit = request.getparameter（ "submit ");
if （submit!=null && !submit.equals（ " ")) {
if（user.add（request)){
session.setattribute（ "username ",user.getusername（));
session.setattribute（ "userid ", long.tostring（ user.getuserid（) ) );
response.sendredirect（ "info.jsp?action=regok ");
} else if （!user.getmessage（).equals（ " ")) {
mesg = user.getmessage（);
} else
mesg = "注册时出现错误，请稍后再试 ";
}

%>
<script language= "javascript ">

function openscript（url,name, width, height){
var win = window.open（url,name, 'width= ' + width + ',height= ' + height + ',resizable=1,scrollbars=yes,menubar=no,status=yes ' );
}

function checkform（) {
if （document.form1.username.value== " "){
alert（ "用户名不能为空 ");
document.form1.username.focus（);
return false;
}
if （document.form1.passwd.value== " "){
alert（ "用户密码不能为空 ");
document.form1.passwd.focus（);
return false;
}
if （document.form1.passwd.value!=document.form1.passconfirm.value){
alert（ "确认密码不相符！ ");
document.form1.passconfirm.focus（);
return false;
}

return true;
}

说明lz下面代码的逻辑流程有问题，总是进入最后的else

if（user.add（request)){
session.setattribute（ "username ",user.getusername（));
session.setattribute（ "userid ", long.tostring（ user.getuserid（) ) );
response.sendredirect（ "info.jsp?action=regok ");
} else if （!user.getmessage（).equals（ " ")) {
mesg = user.getmessage（);
} else
mesg = "注册时出现错误，请稍后再试 ";

是你的user这个bean里面出错了吧。
user.add（request)会返回什么？

少了}吧

mesg = user.getmessage（);

以下是op_user.class部份源码:
//添加新用户
public boolean add（httpservletrequest req) throws exception
{
if （getrequest（req))
{
database db = new database（);
//db.connect（);
//stmt = db.conn.createstatement （);
//sqlstr = "select * from shop_user where username = ' " +
// user.getusername（) + " ' ";
sqlstr = "insert into shop_user （username,password,names,sex, "+
"address,phone,post,email,regtime,regipaddress) values （ ' ";
sqlstr = sqlstr + dataformat.tosql（user.getusername（)) + " ', ' ";
sqlstr = sqlstr + dataformat.tosql（user.getpassword（)) + " ', ' ";
sqlstr = sqlstr + dataformat.tosql（user.getnames（)) + " ', ' ";
sqlstr = sqlstr + dataformat.tosql（user.getsex（)) + " ', ' ";
sqlstr = sqlstr + dataformat.tosql（user.getaddress（)) + " ', ' ";
sqlstr = sqlstr + dataformat.tosql（user.getphone（)) + " ', ' ";
sqlstr = sqlstr + dataformat.tosql（user.getpost（)) + " ', ' ";
sqlstr = sqlstr + dataformat.tosql（user.getemail（)) + " ',getdate（), ' ";
sqlstr = sqlstr + user.getregipaddress（) + " ') ";
try
{
db.stmt.ＥＸＥＣuteupdate（sqlstr);
sqlstr = "select max（id) from shop_user where username = ' " +
dataformat.tosql（user.getusername（))+ " ' ";
rs = db.stmt.ＥＸＥＣutequery（sqlstr);
while （rs.next（))
{
userid = rs.getlong（1);
}
rs.close（);
db.finalize（);
return true;
}
catch （exception sqle)
{
system.out.print（sqle.getmessage（));
return false;
}
}
else
{
return false;
}

lz调用user.add（request)方法能够将数据写入数据库吗？有没有报异常？

发表于：2007-05-22 22:37:269楼得分:0

能写入数据库,应该是那个add方法有问题,可我还是改不出

发表于：2007-05-22 22:44:5410楼得分:20

能写入数据库，add（)方法还是返回false？？？
lz的qq多少？
