如何在 Quarkus 中获取 ThreadFactory?

问题描述

我正在尝试将 JEE 服务迁移到 Quarkus 并想知道如何在 Quarkus 中获取线程工厂应用程序.简单地创建一个像 javaExecutors.defaultThreadFactory(); 在 JavaSE 中?

I'm trying to migrate a JEE service to Quarkus and wonder how to obtain a thread factory in a Quarkus app. Simply create one like javaExecutors.defaultThreadFactory(); as in JavaSE?

在 Java EE 环境中，您通常会使用托管线程工厂来创建要执行的线程:

In a Java EE environment you would normally use a managed thread factory for creating threads for execution:

@Resource
private ManagedThreadFactory mtf;

知道如何在 Quarkus 应用程序中正确执行此操作吗?

Any idea how to do this correctly within a Quarkus app?

补充:不幸的是，无法使用 ManagedExecutor，因为某些库(如 Apache HttpAsyncClient)需要 ThreadFactory 来进行配置.

Addition: Using a ManagedExecutor is unfortunately not possible as some libraries like Apache HttpAsyncClient requires a ThreadFactory for it's configuration.

推荐答案

除非您有需要创建实际线程的特殊用例，否则我建议使用 Executor 而不是 线程工厂.这通常更好，因为您可以将轻量级工作对象(Runnable/Callable/etc)提交给 Executor，它将在 Executor 的线程池(由 Quarkus 管理)上运行)，而不是创建重量级线程.

Unless you have a special use-case that requires creating actual Threads, I would recommend using an Executor instead of a ThreadFactory. This is typically better because you can submit lightweight work objects (Runnable/Callable/etc) to an Executor and it will run on the Executor's thread pool (which is managed by Quarkus), as opposed to creating heavyweight threads.

Quarkus 提供对 MicroProfile Context Propagation 的支持，它基本上是 Java EE Con​​currency 的扩展.要使用它，您可以像这样注入 ManagedExecutor:

Quarkus provides support for MicroProfile Context Propagation, which is basically an extension of Java EE Concurrency. To use it, you can inject a ManagedExecutor like this:

import org.eclipse.microprofile.context.ManagedExecutor;

// ...

@Inject
ManagedExecutor exec;
