spring|spring event|Spring内置事件驱动编程模型|顺序和条件

事件执行谁来决定

类型匹配（Type Match）、条件过滤（Condition Filter）和顺序排序（Ordering）共同决定了事件最终由谁执行、何时执行

源码

https://gitee.com/jysemel-spring/spring-boot/tree/master/action/action-event-order

核心流程图解

第一步（类型匹配） -> 第二步（顺序排序） -> 第三步（条件过滤） -> 第四步（事务相位对齐） -> 执行

条件触发（Condition）结合SpEL表达式

顺序触发（Order）没有order最后执行

代码演示
