Annotation Interface Priority

@Target(METHOD) @Retention(RUNTIME) public @interface Priority
Priority Annotation 优先级注解

Specifies the execution priority of an event handler.

指定事件处理器的执行优先级。

Features | 主要功能:

  • Higher value = higher priority - 值越大优先级越高
  • Default priority is 0 - 默认优先级为0
  • Handlers execute in priority order - 处理器按优先级顺序执行

Usage Examples | 使用示例:

@Subscribe
@Priority(100)  // Executes first
public void validateOrder(OrderCreatedEvent event) {
    if (!isValid(event)) {
        event.cancel();  // Cancel to stop lower priority handlers
    }
}

@Subscribe
@Priority(50)   // Executes second
public void logOrder(OrderCreatedEvent event) {
    log.info("Order created: {}", event.getOrderId());
}

@Subscribe      // Default priority 0, executes last
public void processOrder(OrderCreatedEvent event) {
    orderService.process(event);
}
