Code ví dụ Spring Security login với JDBC, Database MySQL

Posted on by cuongth

Code ví dụ Spring Security login với JDBC, Database MySQL.

Ở bài này mình sẽ thực hiện ví dụ sử dụng Spring JDBC kết nối với MySQL để xác thực với Spring Security.

Các công nghệ sử dụng:

Tạo Database

spring-security.sql

Tạo database “spring-security”

spring security mysql database

 

spring security database login

Tạo table users chứa thông tin username, password và enabled (enabled = 1 tức là account đã được active)

  • CREATE TABLE `spring-security`.`users` (
  • `id` INT NOT NULL AUTO_INCREMENT,
  • `username` VARCHAR(45) NULL,
  • `password` VARCHAR(255) NULL,
  • `enabled` INT NULL,
  • PRIMARY KEY (`id`),
  • UNIQUE INDEX `username_UNIQUE` (`username` ASC));
CREATE TABLE `spring-security`.`users` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(45) NULL,
  `password` VARCHAR(255) NULL,
  `enabled` INT NULL,
  PRIMARY KEY (`id`),
  UNIQUE INDEX `username_UNIQUE` (`username` ASC));

Tạo table role chứa thông tin các role.

  • CREATE TABLE `spring-security`.`role` (
  • `id` INT NOT NULL AUTO_INCREMENT,
  • `name` VARCHAR(45) NULL,
  • PRIMARY KEY (`id`));
CREATE TABLE `spring-security`.`role` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `name` VARCHAR(45) NULL,
  PRIMARY KEY (`id`));

Tạo table users_roles thực hiện mapping để biết user nào có những role nào

  • CREATE TABLE `spring-security`.`users_roles` (
  • `id` INT NOT NULL AUTO_INCREMENT,
  • `user` INT NULL,
  • `role` INT NULL,
  • PRIMARY KEY (`id`),
  • INDEX `_idx` (`user` ASC),
  • INDEX `dfdf_idx` (`role` ASC),
  • CONSTRAINT `user`
  • FOREIGN KEY (`user`)
  • REFERENCES `spring-security`.`users` (`id`)
  • ON DELETE NO ACTION
  • ON UPDATE NO ACTION,
  • CONSTRAINT `role`
  • FOREIGN KEY (`role`)
  • REFERENCES `spring-security`.`role` (`id`)
  • ON DELETE NO ACTION
  • ON UPDATE NO ACTION);
CREATE TABLE `spring-security`.`users_roles` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `user` INT NULL,
  `role` INT NULL,
  PRIMARY KEY (`id`),
  INDEX `_idx` (`user` ASC),
  INDEX `dfdf_idx` (`role` ASC),
  CONSTRAINT `user`
    FOREIGN KEY (`user`)
    REFERENCES `spring-security`.`users` (`id`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT `role`
    FOREIGN KEY (`role`)
    REFERENCES `spring-security`.`role` (`id`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION);

Tạo 2 tài khoản kai/123456 và sena/123456

  • INSERT INTO `users` VALUES (1,'kai','{noop}123456',1),(2,'sena','{noop}123456',1);
INSERT INTO `users` VALUES (1,'kai','{noop}123456',1),(2,'sena','{noop}123456',1);

Tạo 2 role là ROLE_ADMIN và ROLE_USER

  • INSERT INTO `role` VALUES (1,'ROLE_ADMIN'),(2,'ROLE_USER');
INSERT INTO `role` VALUES (1,'ROLE_ADMIN'),(2,'ROLE_USER');

Thiết lập role = “ROLE_ADMIN”, “ROLE_USER” cho tài khoản ‘kai’, và role = “ROLE_USER” cho tài khoản ‘sena’

  • INSERT INTO `users_roles` VALUES (1,1,1),(2,1,2),(4,2,2);
INSERT INTO `users_roles` VALUES (1,1,1),(2,1,2),(4,2,2);

Tạo Maven Project.

Demo:

Login với tài khoản kai/123456

Truy cập trang admin.jsp

Logout.

Login với tài khoản sena/123456

Truy cập trang admin.jsp

Vì tài khoản sena/123456 không có role = “ROLE_ADMIN” nên không thể truy cập trang admin.jsp.
