作为Bean容器，Sping框架提供了Ioc机制，可以接管所有组件的创建工作进行依赖管理，因而整合的主要工作就是把MyBatis框架使用中涉及的核心组件配置到Sping容器中，交给Sping来创建和管理。
业务逻辑对象依赖于MyBatis技术实现的Dao对象，核心是获取SqlSession实例。而SqlSession是通过SqlSessionFactoryBen来获取。
Sping 和MyBatis整合方法：
在整合是用到MyBatis-Sping-1.2.0jar
<!--Mybatis+Spring整合-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.2.0</version>
</dependency>
1、采用MapperScannerConfigurer，它将会查找类路径下的映射器并自动将它们创建成MapperFactoryBean。
spring-mybatis.xml:
例：图书添加。
建立数据库：
创建book实体：
private int id;
private String bookname;
private int bookprice;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getBookname() {
return bookname;
}
public void setBookname(String bookname) {
this.bookname = bookname;
}
public int getBookprice() {
return bookprice;
}
public void setBookprice(int bookprice) {
this.bookprice = bookprice;
}
创建IBookDAO
public interface IBookDAO {
public int addbook(book book);
}
创建IBookDAO.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--映射文件的根节点
namespace
-->
<mapper namespace="cn.happy.day16ssm.dao.IBookDAO">
<insert id="addbook">
insert into bookshop(bookname,bookprice) values(#{bookname},#{bookprice})
</insert>
</mapper>
service层：
IBookService：
public interface IBookService {
public int addbook(book book);
}
BookServiceimpl：
public class BookServiceimpl implements IBookService {
private IBookDAO dao;
public IBookDAO getDao() {
return dao;
}
public void setDao(IBookDAO dao) {
this.dao = dao;
}
public int addbook(book book) {
return dao.addbook(book);
}
}
JDBC的四大属性：
jdbc.url=jdbc:mysql:///bookshop
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.username=root
jdbc.password=
MyBatis的配置文件：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<!--核心配置文件的根节点-->
<configuration>
<!--别名的设置-->
<typeAliases>
<package name="cn.happy.day16ssm.entity"></package>
</typeAliases>
<!--管理小配置-->
</configuration>
