前言：在security初体验（一）里，用户名和密码的认证都是基于内存级别的，本章主要是说security如何从db里取用户名和密码来验证的。

1.准备的sql

  1. DROP TABLE IF EXISTS `user`;
  2. CREATE TABLE `user`  (
  3.   `id` int(11) NOT NULL AUTO_INCREMENT,
  4.   `username` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL,
  5.   `password` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL,
  6.   `enabled` tinyint(1) NULL DEFAULT NULL,
  7.   `locked` tinyint(1) NULL DEFAULT NULL,
  8.   PRIMARY KEY (`id`) USING BTREE
  9. ) ENGINE = InnoDB AUTO_INCREMENT = 4 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic;
  11. INSERT INTO `user` VALUES (1, 'root', '$2a$10$O8G0X/sUPAA76MV7U3BwY.3Uo8/QMBcqK678Rwkoz.fowbce.CLtO', 1, 0);
  12. INSERT INTO `user` VALUES (2, 'admin', '$2a$10$O8G0X/sUPAA76MV7U3BwY.3Uo8/QMBcqK678Rwkoz.fowbce.CLtO', 1, 0);
  13. INSERT INTO `user` VALUES (3, 'tom', '$2a$10$O8G0X/sUPAA76MV7U3BwY.3Uo8/QMBcqK678Rwkoz.fowbce.CLtO', 1, 0);
  15. DROP TABLE IF EXISTS `role`;
  16. CREATE TABLE `role`  (
  17.   `id` int(11) NOT NULL AUTO_INCREMENT,
  18.   `name` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL,
  19.   `description` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL,
  20.   PRIMARY KEY (`id`) USING BTREE
  21. ) ENGINE = InnoDB AUTO_INCREMENT = 4 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic;
  23. INSERT INTO `role` VALUES (1, 'db', '数据库管理员');
  24. INSERT INTO `role` VALUES (2, 'admin', '系统管理员');
  25. INSERT INTO `role` VALUES (3, 'user', '用户');
  27. DROP TABLE IF EXISTS `user_role_ref`;
  28. CREATE TABLE `user_role_ref`  (
  29.   `id` int(11) NOT NULL AUTO_INCREMENT,
  30.   `user_id` int(11) NULL DEFAULT NULL,
  31.   `role_id` int(11) NULL DEFAULT NULL,
  32.   PRIMARY KEY (`id`) USING BTREE
  33. ) ENGINE = InnoDB AUTO_INCREMENT = 5 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic;
  35. INSERT INTO `user_role_ref` VALUES (1, 1, 1);
  36. INSERT INTO `user_role_ref` VALUES (2, 1, 2);
  37. INSERT INTO `user_role_ref` VALUES (3, 2, 2);
  38. INSERT INTO `user_role_ref` VALUES (4, 3, 3);

  19.         return "hello db";
  20.     }
  21.     @GetMapping("/user/hello")
  22.     public String user() {
  23.         return "hello user";
  24.     }
  25. }

10.测试

1.用admin账号登录，只能访问/admin/hello接口

2.admin账号不能访问其他两个接口

11.角色继承

1.配置

2.测试
1）登录root账号发现其可以访问/user/hello，/admin/hello，/db/hello这三个接口
