Spring_事务操作:XML声明式事务管理及完全注解开发

XML声明式事务管理

1.在Spring配置文件中进行配置

第一步：配置事务管理器

    <!--1.创建事务管理器-->
    <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"></property>
    </bean>

第二步：配置通知

    <!--2.配置通知-->
    <tx:advice id="txadvice">
        <tx:attributes>
            <tx:method name="accoubtMoney" propagation="MANDATORY"/>
        </tx:attributes>
    </tx:advice>

第三步：配置切入点和切面

    <!--3.配置切入点-->
    <aop:config>
        <!--配置切入点-->
        <aop:pointcut id="pt" expression="execution(* com.tinstu.spring.service.BankService.*(..))"/>
        <!--配置切面-->
        <aop:advisor advice-ref="txadvice" pointcut-ref="pt"></aop:advisor>
    </aop:config>

        <!--配置切入点-->
        <aop:pointcut id="pt" expression="execution(* com.tinstu.spring.service.BankService.*(..))"/>
        <!--配置切面-->
        <aop:advisor advice-ref="txadvice" pointcut-ref="pt"></aop:advisor>
    </aop:config>
</beans>

完全注解开发

创建一个配置类替代配置文件：

package com.tinstu.spring.config;

import com.alibaba.druid.pool.DruidDataSource;
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;


@Configuration   //配置类
@ComponentScan(basePackages = "com.tinstu.spring")
@EnableTransactionManagement  //开启事务
public class TxConfig {
    //创建数据库连接池
    @Bean
    public DruidDataSource getDruidDataSource(){
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/bookjdbc?serverTimezone=UTC");
        dataSource.setUsername("root");
        dataSource.setPassword("root");
        return dataSource;
    }
    //创建JdbcTemplate对象
    public JdbcTemplate getJdbcTemplate(DataSource dataSource){
        JdbcTemplate jdbcTemplate = new JdbcTemplate();
        //注入dataSource
        jdbcTemplate.setDataSource(dataSource);
        return jdbcTemplate;
    }
    //创建事务管理器对象
    @Bean
    public DataSourceTransactionManager dataSourceTransactionManager(DataSource dataSource){
        DataSourceTransactionManager transactionManager = new DataSourceTransactionManager();
        transactionManager.setDataSource(dataSource);
        return transactionManager;
    }
}
