08ssm三大框架整合

assm
spring framework Ioc容器
spring mvc web项目
mybatis orm持久层框架 ssm 整合
---------------------------------------------------------------
1、建立maven web项目 pom.xml 内容如下：

2、准备项目数据库信息
mysql> use db;
Database changed
mysql> desc book;
+------------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+------------+------------------+------+-----+---------+----------------+
| book_id | int(10) unsigned | NO | PRI | NULL | auto_increment |
| book_name | varchar(20) | YES | | NULL | |
| book_price | decimal(8,2) | YES | | NULL | |
+------------+------------------+------+-----+---------+----------------+
3 rows in set (0.08 sec)

mysql> select * from book;
+---------+---------------------------------+------------+
| book_id | book_name | book_price |
+---------+---------------------------------+------------+
| 2 | 《java入门与精通》 | 355.00 |
