1、Spring
Spring是一个开源框架，Spring是于2003 年兴起的一个轻量级的Java 开发框架，由Rod Johnson 在其著作Expert One-On-One J2EE Development and Design中阐述的部分理念和原型衍生而来。它是为了解决企业应用开发的复杂性而创建的。Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。然而，Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。 简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。
2、MyBatis
MyBatis 本是apache的一个开源项目iBatis, 2010年这个项目由apache software foundation 迁移到了google code，并且改名为MyBatis 。MyBatis是一个基于Java的持久层框架。iBATIS提供的持久层框架包括SQL Maps和Data Access Objects（DAO）MyBatis 消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映射，将接口和 Java 的POJOs（Plain Old Java Objects，普通的 Java对象）映射成数据库中的记录。

2.创建JDBC.properties文件
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/y2167?useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=
3.创建Spring-MyBatis.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!--配置数据源-->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<!--识别jdbc.properties文件-->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!--把SqlSessionFactory生产权交给spring-->
<bean class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
</bean>
<!--DAO-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--设置包路径-->
<property name="basePackage" value="cn.happy.day16SSM.dao"/>
</bean>
<!--service-->
<bean id="bookservice" class="cn.happy.day16SSM.service.BookServiceImpl">
<!--注意事项：如果接口是以I开头，那么会默认在内存中默认生成一个与接口名字一样的实现类如IXXXDAO
如果不是一I开头，则默认生成第一个小写字母开头如 xXXDAO
-->
<property name="dao" ref="IBookDAO"/>
</bean>
</beans>
4.数据库结构
4.创建接口实体类
代码如下
package cn.happy.day16SSM.dao;
import cn.happy.day16SSM.entity.Book;
/**
* Created by Administrator on 2018/3/16.
*/
public interface IBookDAO {
//添加图书
public int addBook(Book book);
}
DAO.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">
<!--namespace:接口绝对路径-->
<mapper namespace="cn.happy.day16SSM.dao.IBookDAO">
<!--根据Id修改Name-->
<insert id="addBook">
INSERT into book(bookName,bookAuthor,bookPrice)VALUES (#{bookName},#{bookAuthor},#{bookPrice})
</insert>
</mapper>
entity
package cn.happy.day16SSM.entity;
/**
* Created by Administrator on 2018/3/16.
*/
public class Book {
private Integer bookId;
private String bookName;
private String bookAuthor;
private Integer bookPrice;
public Integer getBookId() {
return bookId;
}
public void setBookId(Integer bookId) {
this.bookId = bookId;
}
public String getBookName() {
return bookName;
}
public void setBookName(String bookName) {
this.bookName = bookName;
}
public String getBookAuthor() {
return bookAuthor;
}
public void setBookAuthor(String bookAuthor) {
this.bookAuthor = bookAuthor;
}
public Integer getBookPrice() {
return bookPrice;
}
public void setBookPrice(Integer bookPrice) {
this.bookPrice = bookPrice;
}
}
serviceImpl
package cn.happy.day16SSM.service;
import cn.happy.day16SSM.dao.IBookDAO;
import cn.happy.day16SSM.entity.Book;
/**
* Created by Administrator on 2018/3/16.
*/
public class BookServiceImpl implements BookService {
//
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);
}
}
5.测试类
package day16SSM;
import cn.happy.day15tx.service.IStockService;
import cn.happy.day16SSM.dao.IBookDAO;
import cn.happy.day16SSM.entity.Book;
import cn.happy.day16SSM.service.BookService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/**
* Created by Administrator on 2018/3/3.
*/
public class Test20180316 {
//Spring+MyBatis整合
@Test
public void Spring(){
ApplicationContext ctx=new ClassPathXmlApplicationContext("Spring-MyBatis.xml");
BookService service=(BookService)ctx.getBean("bookservice");
Book book=new Book();
book.setBookName("JAVA Web");
book.setBookAuthor("许令波");
book.setBookPrice(60);
service.addBook(book);
}
}
测试结果
