Maven整合SSM

准备表

  1. CREATE TABLE `book` (
  2.   `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '图书ID',
  3.   `name` varchar(100) NOT NULL COMMENT '图书名称',
  4.   `number` int(11) NOT NULL COMMENT '图书数量',
  5.   `detail` varchar(200) NOT NULL COMMENT '图书描述',
  6.   PRIMARY KEY (`book_id`)
  7. ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='图书表'
