SpringMVC - 03

整合 SSM 上篇

用到的环境：

IDEA 2019（JDK 1.8）
MySQL 8.0.31
Tomcat 8.5.85
Maven 3.6.1

一、准备工作

分析需求，准备一个数据库

CREATE DATABASE IF NOT EXISTS `ssmbuild`;

use `ssmbuild`;

CREATE TABLE IF NOT EXISTS `books`(
		`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书ID', 
		`bookName` VARCHAR(100) NOT NULL DEFAULT '' COMMENT '书名', 
		`bookCounts` INT(50) NOT NULL DEFAULT 0 COMMENT '书的数量', 
		`detail` VARCHAR(100) NOT NULL DEFAULT '' COMMENT '描述', 
		PRIMARY KEY(`bookID`)
)ENGINE=INNODB DEFAULT charset=utf8mb4;


INSERT INTO `books`(`bookID`, `bookName`, `bookCounts`, `detail`) VALUES 
(1, '高等数学', 2, '第一排第一个'), 
(2, '计算机网络', 5, '第二排第二个'), 
(3, '通信原理', 3, '第一排第三个');

新建一个项目，导入依赖
