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>--> <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--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" isolation="DEFAULT" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="mypoint" expression="execution(* *..service.*.add*(..))"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="mypoint"/> </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"> <configuration> <typeAliases> <package name="cn.bdqn.bean"/> </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 namespace="cn.bdqn.dao.IUserDao"> <insert id="addUser"> INSERT into user(name,address,birthday) VALUES (#{name},#{address},#{birthday}) </insert> </mapper>
5>pom.xml

1>实体类Student
public class User implements Serializable { private int id; private String name; private String address; private Date birthday; public User() { } public User(int id, String name, String address, Date birthday) { this.id = id; this.name = name; this.address = address; this.birthday = birthday; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } @Override public String toString() { return "User{" + "id=" + id + ", name=\'" + name + \'\\\'\' + ", address=\'" + address + \'\\\'\' + ", birthday=" + birthday + \'}\'; } }
2>dao接口

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) { this.userDao = 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); } }
