Я хочу сделать перенаправление после действия входа на мою индексную страницу (index. jsp), фактически мой вход в систему работает, но перенаправление отсутствует с поддержкой ajax.
Она - мой вход . jsp
<html>
<head>
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
<script type="text/javascript" src="js/jquery-3.1.1.min.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>
<script type="text/javascript">
function loginUser() {
var username = $("#username").val();
var userpass = $("#userpass").val();
$.ajax({
type : "POST",
url : "loginuser.action",
data : "username=" + username + "&userpass=" + userpass,
success : function(data) {
var ht = data.msg;
$("#resp").html(ht);
},
error : function(data) {
alert("Some error occured.");
}
});
}
</script>
</head>
<body style="text-align: center;">
<div class="container ">
<div class="col-lg-4">
<div class="form-group">
<input type="text" name="username" id="username"
class="form-control input-sm" placeholder="User Name">
</div>
<div class="form-group">
<input type="password" name="userpass" id="userpass"
class="form-control input-sm" placeholder="Password">
</div>
<button onclick="loginUser();" type="button" class="btn btn-success btn-block">Login</button>
<div class="text-center" id="resp" style="margin-top: 14px;"></div>
</div>
</div>
вот мой LoginAction
public class LoginAction extends ActionSupport {
private static final long serialVersionUID = 5569022937143602032L;
private String username, userpass, msg;
Admin dao = null;
public String execute() throws SQLException, Exception {
dao = new Admin();
msg = dao.validate(username, userpass);
return msg;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getUserpass() {
return userpass;
}
public void setUserpass(String userpass) {
this.userpass = userpass;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
}
мой файл конфигурации распорок:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC

</package>
для части DAO:
publi c Проверка строки (String username, String userpass) выдает SQLException, Exception {
boolean status = false;
try {
String sql = "select * from USERS where UNAME=? and UPASS=?";
PreparedStatement ps = myconnection().prepareStatement(sql);
ps.setString(1, username);
ps.setString(2, userpass);
ResultSet rs = ps.executeQuery();
status = rs.next();
if (status == true)
return "Login Successful";
else
return "Login Failed";
} catch (Exception e) {
e.printStackTrace();
return e.getMessage();
} finally {
if (myconnection() != null) {
myconnection().close();
}
}
}
Спасибо за вашу помощь .
