Я пытался создать страницу входа в систему, используя область JDBC, но это не помогло.
Мои шаги:
- Создание базы данных, таблицы пользователей и групп
- Создание пула соединений и источника данных, пользовательской области.
- Добавление сопоставления ролей безопасности, ограничения входа в систему, ограничения безопасности и роли безопасности.
- Создание jsp входа и сервлета входа в систему
Я могу пропинговать пул соединенийво время создания.
Какая минимальная конфигурация требуется для выполнения вышеуказанной задачи?
Мой код:
create table login
(
username varchar(128) NOT NULL CONSTRAINT usernamePk primary key,
password varchar(128) NOT NULL
);
insert into Login values('peterwkc', '1234');
create table grouptable
(
username varchar(128) NOT NULL,
groupid varchar(128) NOT NULL,
CONSTRAINT GROUP_PK PRIMARY KEY(username, groupid),
CONSTRAINT USER_FK FOREIGN KEY(username) REFERENCES Login (username)
ON DELETE CASCADE ON UPDATE RESTRICT
);
