spring mvc 实战化项目之三板斧
接上文希望从一张表（tb_role_info 用户角色表）的CRUD展开spring mvc的项目实战化魅力。
开发技术选型：spring mvc+freemarker+bootstrap+mybatis+mysql。
项目目录结构：
(1)业务表 tb_role_info
-- ------------------------------ Table structure for `tb_role_info` 用户角色表-- ----------------------------DROP TABLE IF EXISTS `tb_role_info`;CREATE TABLE `tb_role_info` ( `id` int(11) NOT NULL AUTO_INCREMENT, `role_name` varchar(32) NOT NULL DEFAULT ‘‘ COMMENT ‘角色名称‘, `role_mark` varchar(255) DEFAULT ‘‘ COMMENT ‘角色备注‘, `creater_id` int(11) NOT NULL DEFAULT ‘0‘ COMMENT ‘记录创建者id‘, `created_at` timestamp NULL DEFAULT NULL COMMENT ‘创建日期‘, `updated_at` timestamp NULL DEFAULT NULL COMMENT ‘更新日期‘, `time_stamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT ‘记录更新时间戳‘, PRIMARY KEY (`id`), KEY `tb_role_info_index` (`id`,`role_name`,`creater_id`) USING BTREE) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT=‘角色信息表‘;
