使用@Scheduled Annotation运行某些代码时，需要定义上下文。否则会出现此异常，因为使用累积性API的线程不在任何上下文中。

例如对于所有订阅的租户：

private final MicroserviceSubscriptionsService subscriptions;

@Scheduled(fixedDelay = 5 * 60 * 1000)
private void checkForAgentRepresentation() {
    for (final MicroserviceCredentials mc : subscriptions.getAll()) {
        final String tenant = mc.getTenant();
        subscriptions.runForTenant(tenant, () -> {
            //doSomething like
            inventoryApi.get(...);
        });
    }
}

创建名称为“ scopedTarget.userPlatform”的bean时出错：作用域“用户”在当前线程中未激活
