如何在应用启动时执行更多的Spring bean方法

Question

I have a spring bean with 4 blocking queues. Each queue is assigned a method (named processQueueX() ) which calls take() on that queue and processes taken object from queue.

I want to call each of those method in a separate thread on app startup. I tried with task scheduler and fixed-delay setting but that in some way blocks tomcat and it stops responding to requests. Each method needs to be called once, so scheduling was a bad idea I guess.

Init method does not work also since it works in a single thread, each method has endless loop to process queue forever.

Is there a way to call these methods declaratively from spring config file in manner similar to task namespace? Or programmatically?

Tnx

我认为使用调度程序不是一个坏主意，使用具有简单触发器的quart调度程序，因此quarz将为您执行线程操作并且tomcat不会受到影响。并使用足够数量的线程配置石英。

Would 23.4. The Spring TaskExecutor abstraction help?

Where the example has a MessagePrinterTask class, you would have similar, but your run() method would access one of the queues. You would set up your Spring config to inject one of the queues into the task, so depending on how similar your queues are, you might be able to use the same Runnable task.
