嗯，把代码下下来看了下，这里就启动了`Filter`链（感觉和之前的`Handler`有点像，`invocation.next(xxx)`）
```java
public CompletableFuture<Response> onFilter(Invocation invocation) {
if (!filter.enabled()) {
return nextNode.onFilter(invocation);
}
return AsyncUtils.tryCatch(() -> filter.onFilter(invocation, nextNode))
.thenApply(this::rethrowExceptionInResponse);
}
```
而且现在`Filter`可以使用`Autowire`了吧 :)
```java
engine.getApplicationContext().getAutowireCapableBeanFactory().autowireBean(filter)
```
不过我现在还有个疑问，就是我在`Handler`中用了异步（如issue中第一个描述中的代码），自己定义的线程池，然后我`debug`的时候发现后续的`Invocation#next`执行的时候也都在我自定义的线程池中执行，后续的操作还有可能切换到eventloop线程中执行么？
