Spring整合MyBatis
 思想:整合一定不是两个框架jar包简单的堆砌  真正的思想是Spring接管了MyBatis框架的一部分工作
 1.SqlSessionFactory  创建权交给Spring
   生成SqlSession,打通通道

 2.如果你想将咱们的DAO配置到Spring。接口实现类
 <bean id="bookDAO" class="MapperScannerConfig">


你接口的命名规范起到非常重要的作用
接口以I开头,生成对象就是接口名称本身 IBookDAO  IBookDAO
没有以I开头, BookDAO  对象的名称 bookDAO


整合最根本的点:
1.Spring生成工厂
    SqlSessionFactoryBean------>dataSource  和mybatis-config.xml

Spring 整合JavaWeb
 spring-web
 

 

 

 

 

整体结构如下图:

1、配置文件:

1>applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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
        http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
         http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--01.加载jdbc.properties文件-->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!--02.配置数据源  002.使用dbcp数据源-->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="${jdbc.driverClass}"/>
        <property name="url" value="${jdbc.jdbcUrl}"/>
        <property name="username" value="${jdbc.userName}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

    <!--03. 配置sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="configLocation" value="classpath:mybatisContext.xml"/>
        <property name="dataSource" ref="dataSource" />
        <!-- 自动扫描mapping.xml文件,**表示迭代查找 ,,也可在mybatis-config.xml中单独指定xml文件
         <property name="mapperLocations" value="classpath:cn/bdqn/dao/*.xml"/>
         -->
    </bean>

<!-- 04.配置userDao-->
   <!-- <bean id="userDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
        <property name="mapperInterface" value="cn.bdqn.dao.UserDao"/>
        <property name="sqlSessionFactory" ref="sqlSessionFactory"/>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.bdqn.dao"/>
    </bean>
    <!--05.配置service-->
    <bean id="userService" class="cn.bdqn.service.impl.UserServiceImpl">
        <property name="userDao" ref="IUserDao"/>
    </bean>
    <!--06.配置事务-->

    </aop:config>
<!--扫描注解定义-->
    <!--<context:component-scan base-package="cn.bdqn.service"/>-->
</beans>

 

2>jdbc.properties外置文件:

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql:///mybatis
jdbc.userName=root
jdbc.password=000

3>mybatis-config.xml

 

<?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">

    </typeAliases>
    <!--可以省略<mappers>
        <package name="cn.bdqn.dao"/>
    </mappers>-->
</configuration>

4>IUserDao.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">

</mapper>

1>实体类Student

public class User implements Serializable {

    private String name;
    private String address;
    private Date birthday;

    public User() {
    }

    public User(int id, String name, String address, Date birthday) {

                ", birthday=" + birthday +
                ‘}‘;
    }
}

2>dao接口

public interface IUserDao {
    /**
     * 添加用户
     * @param user user对象
     * @return 影响横数
     */
    int addUser(User user);
}

3>service

public interface UserService  {
    int addUser(User user);

4.>serviceImpl

public class UserServiceImpl implements UserService{
    private IUserDao userDao;
    public int addUser(User user) {
        return userDao.addUser(user);
    }

    public IUserDao getUserDao() {
        return userDao;
    }

    public void setUserDao(IUserDao userDao) {

5.test:

public class test01 {
    @Test
    public void test(){
        ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
        UserService userService = (UserService) context.getBean("userService");
        User user=new User();
        user.setName("小明");
        user.setAddress("五道口");
        user.setBirthday(new Date());
        userService.addUser(user);
    }
}
