У меня проблема с логином безопасности Spring в моем приложении. Моя страница входа на сайт продавца / URL-адрес входа, URL-адрес обработки устанавливается на / loginProcessing, после отправки данных для входа в форму:
<form name="loginform" action="/loginProcessing" method="POST">
<table>
<tr>
<td>Enter username:</td>
<td><input type='text' name='username' value=''></td>
</tr>
<tr>
<td>Enter password:</td>
<td><input type='password' name='password' /></td>
</tr>
<tr>
<td colspan="2"> </td>
</tr>
<tr>
<td colspan='2'><input name="submit" type="submit" value="Submit" /></td>
</tr>
</table>
</form>
Я всегда перенаправлен на страницу ошибки входа со статусом 302 при обработке входа, независимо от того, если логин и пароль верны. Вы знаете, почему это происходит каждый раз? Sql запросов в spring-security. xml для проверки правильности данных для входа в систему, пароли в базе данных хранятся в виде простого текста
