Java学习笔记-spring整合mybatis

这个项目就是一个例子，只有添加图书的功能：

项目架构：

resource：

整合流程：

1.pom文件节点，这两个是整合用的，其他节点不再赘述：

<!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>1.2.0</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.2.2</version>
        </dependency>

如果mybatis用的是3.4.1，那么mybatis-spring版本要用1.3.0

2.applicationContextDay06.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="

">
    <!--01.识别jdbc.properties文件-->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!--02.数据源-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <!--<property name="maxActive" value="20"/>-->
    </bean>
    <!--03.工厂配置 datasource+mybatis-config-->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" p:dataSource-ref="dataSource" p:configLocation="classpath:mybatis-config.xml"/>
    <!--04.Dao层Mapper注入-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage="cn.happy.day06zhenghe.dao"/>
    <!--05.service-->
    <bean id="bookService" class="cn.happy.day06zhenghe.service.impl.BookServiceImpl" p:bookDAO-ref="IBookDAO"/>
    <!--06.transactionManager-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" p:dataSource-ref="dataSource"/>
    <!--07.AspectJ AOP 配置事务-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="addBook" isolation="DEFAULT" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>
    <aop:config>
        <!--切点-->
        <aop:pointcut id="pointcut" expression="execution(* *..day06zhenghe.service.*.*(..))"/>
        <!--顾问-->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
    </aop:config>
</beans>

3.jdbc.properties,这里把四个串配上就行了。

4.mybatis,不用配置environments和mappers了，可以setting和alias，也可以直接干掉这个文件。

5.测试类：

public class Test20171021 {
    @Test
    public void test01(){
        ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContextDay06.xml");
        IBookService bookService = (IBookService)ctx.getBean("bookService");
        Book book = new Book();
        book.setBookname("放学后");
        book.setBookprice((double) 20);
        bookService.addBook(book);
    }
}
