SSM（Spring+SpringMVC+MyBatis）整合+CRUD【IDEA版】

• 以下数据与实际不符，仅用于测试

drop database if exists ssm;

create database ssm;

use ssm; 

##创建图书表
create table t_book(
    `id` int(11) primary key auto_increment,    ## 主键
    `name` varchar(50) not null,                ## 书名 
    `author` varchar(50) not null,              ## 作者
    `price` decimal(11,2) not null,             ## 价格
    `sales` int(11) not null,                   ## 销量
    `stock` int(11)                             ## 库存
);

## 插入初始化测试数据
insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , '平凡的世界' , '路遥' , 80 , 9999 , 9 );

insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , '如何阅读一本书' , '莫提默·J. 艾德勒' , 78.5 , 6 , 13 );

insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , '月亮与六便士' , '毛姆' , 68, 99999 , 52 );

insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , '白夜行' , '东野圭吾' , 16, 1000 , 50 );

insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , 'Java编程思想' , '埃克尔' , 45.5 , 14 , 95 );

insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , '三体' , '刘慈欣' , 9.9, 12 , 53 );
 
insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , '龙族' , '江南' , 66.5, 125 , 535 );

insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , '简爱' , '夏洛蒂·勃朗特' , 99.5 , 47 , 36 );

insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , '大话设计模式' , '吴强' , 89.15 , 20 , 10 );
 
insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`) 
values(null , '人月神话' , '布鲁克斯' , 88.15 , 20 , 80 ); 

## 查看表内容
select id,name,author,price,sales,stock from t_book;

2.创建web项目

3.导入相关jar包

（1）在web项目的web-inf目录下，创建libs文件夹，用于存放jar包

（2）将jar包添加到项目中

4.将项目部署到 tomcat

• 启动tomcat，进行测试

• 如果启动不成功时，可以build一下，重新构建模块

5.使用MBG，生成相关的mybatis代码

（1）MBG配置文件
