AOP事务配置的3种方式
注解和xml结合方式

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

<property name="password" value=""/>
<property name="driverClass" value="com.mysql.jdbc.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql://127.0.0.1:3306/test?charsetEncoding=utf-8"/>
</bean>
<!--配置spring jdbctemplate 使用c3p0 数据源-->
<bean class="org.springframework.jdbc.core.JdbcTemplate" id="jdbcTemplate">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 事物管理器配置-->
<bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="manager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!--开启事物注解-->
<tx:annotation-driven/>
</beans>
- 然后就可以愉快的在需要事务的类和方法上使用@Transactional(value="manager")注解了 value的值是xml配置的事务管理器的id,如果没有指定value则默认value="transactionManager" 在xml中事务管理器的id需要使用默认的transactionManager
xml文件配置方式
<?xml version="1.0" encoding="UTF-8"?>

<!-- 事物管理器配置-->

</bean>
<!--事物通知方法-->
<tx:advice id="txadvice" transaction-manager="manager">
<tx:attributes>
<tx:method name="user*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
<!-- 切面和切点配置 -->
<aop:config>
<aop:pointcut id="pt" expression="execution(* com.hua.service.UserService.*(..))"/>
<aop:advisor advice-ref="txadvice" pointcut-ref="pt"/>
</aop:config>
</beans>
- 在xml中配置要使用事务的方法 和 事物属性
<tx:method name="user*" propagation="REQUIRED"/>
全注解方式
package com.hua.config;
import com.mchange.v2.c3p0.ComboPooledDataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import javax.sql.DataSource;
import java.beans.PropertyVetoException;
@Configuration // 配置类
@ComponentScan(basePackages="com.hua") // 配置包扫描
@EnableTransactionManagement // 开启事务注解
public class TxConfig {
// datasource config
@Bean
public ComboPooledDataSource getDataSource() throws PropertyVetoException {
ComboPooledDataSource dataSource = new ComboPooledDataSource();
dataSource.setUser("root");
dataSource.setPassword("");
dataSource.setDriverClass("com.mysql.jdbc.Driver");
dataSource.setJdbcUrl("jdbc:mysql://127.0.0.1:3306/test?charsetEncoding=utf-8");
return dataSource;
}
// JdbcTemplate config
@Bean
public JdbcTemplate getJdbcTemplate(DataSource dataSource) {
// dataSource 这个参数springioc会依据class来注入
JdbcTemplate jdbcTemplate = new JdbcTemplate();
jdbcTemplate.setDataSource(dataSource);
return jdbcTemplate;
}
// DataSourceTransactionManager config
@Bean
public DataSourceTransactionManager getTransactionManager(DataSource dataSource) {
DataSourceTransactionManager dataSourceTransactionManager = new DataSourceTransactionManager();
dataSourceTransactionManager.setDataSource(dataSource);
return dataSourceTransactionManager;
}
}
@Transactional()
public void userAccount() {
userDao.addMoney();
int a = 1 / 0;
userDao.jianMoney();
}
===================================
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(TxConfig.class);
UserService userService = (UserService) context.getBean("userService");
userService.userAccount();
