1.dao层接口+实现类;java
2.service层接口+实现类;mysql
3.applicationContext.xml配置spring
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" 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"> <!-- 还有好多约束没有添加上面 --> <!-- dataSource 与数据库相连 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver"></property> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/wangyongwu_01"></property> <property name="user" value="root"></property> <property name="password" value="root"></property> </bean> <bean id="accountDaoid" class="com.heima.account01.AccountDaoImp"> <property name="database" ref="database"></property> </bean> <bean id="accountServiceid" class="com.heima.account01.AccountServiceImp"> <property name="accountDaoid" ref="accountDaoid"></property> </bean> <!-- service代理类 --> <bean id="proxyAccountService" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> <property name="proxyInterfaces" ref="com.heima.spring.代理半自动.AccountService"></property> <property name="target" ref="accountService"></property> <property name="transactionManager" ref="txManager"></property> <property name="transactionAttributes" > <props> <prop key="transfer"> PROPAGATION_REQUIRED,ISOLATION_DEFAULT</prop> </props> </property> </bean> <!-- 配置事务管理器 --> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> </beans>
4.测试类sql
public class Test { public static void main(String[] args) { String xmlPath="/spring/src/com/heima/spring/代理半自动/applicationContext.xml"; ApplicationContext applicationContext = new ClassPahtXmlApplicationContext(xmlPath); AccountService accountService =(AccountService)applicationContext.getBean("proxyAccountService"); accountService.transfer("zhangsan", "lisi", 200); } }
