SSM简易整合模板

一个关于图书的增删改查模板
这里只实现了查询图书的controller和jsp

数据库创建

CREATE DATABASE `ssm`;

CREATE TABLE `books`(
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT(11) NOT NULL COMMENT '数量',
`detail` VARCHAR(200) NOT NULL COMMENT '描述',
KEY `bookID`(`bookID`)
)ENGINE=INNODB DEFAULT CHARSET=utf8;

INSERT INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`) VALUES
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');
