3、撸袖开干3.1、环境搭建在环境搭建这一块主要是以代码块为主，因为这一块没有涉及到很多的新知识（默认新知识只有Spring Security?），但是每一个代码内或外都会有或多或少的解释注明这一块是用来干哈子的 。
3.1.1、数据库1、MySQL数据库搭建 。因为这里只是用作学习Spring Security的，所以数据库中一个表足以满足它的欲望了，因此只有一个用户表 。
CREATE DATABASE IF NOT EXISTS db_security;-- ------------------------------ Table structure for sys_user-- ----------------------------DROP TABLE IF EXISTS `sys_user`;CREATE TABLE `sys_user`(`id` bigint(0) NOT NULL AUTO_INCREMENT COMMENT '主键',`user_name` varchar(64) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT 'NULL' COMMENT '用户名',`nick_name` varchar(64) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT 'NULL' COMMENT '昵称',`password` varchar(64) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT 'NULL' COMMENT '密码',`status` char(1) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT '0' COMMENT '账号状态（0正常 1停用）',`email` varchar(64) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '邮箱',`phonenumber` varchar(32) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '手机号',`sex` char(1) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '用户性别（0男，1女，2未知）',`avatar` varchar(128) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '头像',`user_type` char(1) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT '1' COMMENT '用户类型（0管理员，1普通用户）',`create_by` bigint(0) NULL DEFAULT NULL COMMENT '创建人的用户id',`create_time` datetime(0) NULL DEFAULT NULL COMMENT '创建时间',`update_by` bigint(0) NULL DEFAULT NULL COMMENT '更新人',`update_time` datetime(0) NULL DEFAULT NULL COMMENT '更新时间',`del_flag` int(0) NULL DEFAULT 0 COMMENT '删除标志（0代表未删除，1代表已删除）',PRIMARY KEY (`id`) USING BTREE) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci COMMENT = '用户表' ROW_FORMAT = Dynamic;-- ------------------------------ Records of sys_user-- ----------------------------INSERT INTO `sys_user` VALUES (1, 'xbaozi', '陈宝子', '$2a$10$WCD7xp6lxrS.PvGmL86nhuFHMKJTc58Sh0dG1EQw0zSHjlLFyFvde', '0', NULL, NULL, NULL, NULL, '1', NULL, NULL, NULL, NULL, 0);2、Redis搭建 。如果是第一次使用Redis的话介绍太长了，虽然也有写到Redis的安装配置，但是没有上传上来还躺在我的电脑里，所以大家直接去搜一下就可以啦 。
3.1.2、项目搭建1、相关依赖导入 。这里主要导入一些基本依赖和数据库以及Spring Security涉及到的依赖 。
