我们借用这个逻辑将事务管理相关提取到切面中,并在进入目标方法之前,让多个TransactionManager都开启事务,并在成功执行后一并提交或失败后一并回滚,具体代码: /** * @author Zhu * @date 2015-7-15 * @version 0.0.1 * @description */ public class MultiTransactionalAspect { ...
使用DynamicDataSource实现动态数据源切换：基于Spring AOP+自定义注解，利用AbstractRoutingDataSource的继承结构实现。通过创建Map存储数据源，根据不同Service方法调用选择对应数据源，实现不同数据库表的事务处理。事务处理：自定义MultiDataSourceTransaction：动态获取不同Connection，避免从缓存中获取，确保跨数据...
在Spring Boot中配置多数据源及DataSourceTransactionManager以支持多数据源事务管理,可以按照以下步骤进行: 1. 创建和配置多个数据源 首先,在application.yml或application.properties中配置多个数据源。例如: yaml spring: datasource: primary: url: jdbc:mysql://localhost:3306/primary_db username: root password: ...
