ACID（原子性、一致性、隔离性、持久性）四个特性。</p><ul><li><strong>原子性</strong>：指事务作为一个整体来执行，要么全都执行，要么全不执行。</li><li><strong>一致性</strong>：指事务应确保数据从一个一致的状态转变为另一个一致的状态。</li><li><strong>隔离性</strong>：指多个事务并发执行时，一个事务的执行不应影响其他事务的执行。</li><li><strong>持久性</strong>：指已提交事务修改的数据会被持久保存。</li></ul><p>在单一数据节点中，事务仅限于对单一数据库资源的访问控制，称之为本地事务。在基于 Spring 的开发中，我们一般使用 <code>@Transactional</code> 注解的声明式事务来管理。</p><h2 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="分布式事务概念">分布式事务概念<a class="hash-link" href="#分布式事务概念"

的强一致性事务</strong><br>XA模式是传统的强一致性分布式事务解决方案，性能较低且锁资源竞争突出。XA的实现方式存在长事务风险且锁资源严重。在实际业务中使用较少，本文不做更多讨论。</li><li><strong>追求最终一致性的柔性事务</strong><br>柔性事务通过放宽对强一致性要求，而是通过反向补偿来达到最终一致性，同时换取系统吞吐量的提升和缓解锁资源竞争。目前，Seata 框架提供了多种事务管理模式来支持柔性事务的落地实现。（详见后续章节）</li></ul><details class="details_lb9f alert alert--info details_b_Ee" data-collapsed="true"><summary><b>快速 QA：</b>在单体架构的应用中也会有分布式事务吗？</summary><div><div
