直接使用Spring @Async与CompleteableFuture有什么优势? [英] What advantage is there to using Spring @Async vs. CompleteableFuture directly?

问题描述

使用 Spring异步和仅返回CompletableFuture靠你自己?

What's the advantage of using Spring Async vs. Just returning the CompletableFuture on your own?

推荐答案

您的应用程序由容器管理.由于不建议自己生成Thread，因此可以让容器注入托管的Executor.

Your application is managed by the container. Since it's discouraged to spawn Threads on you own, you can let the container inject a managed Executor.

@Service
class MyService {
  @Autowired
  private Executor executor;

  public CompletableFuture<?> compute() {
    return CompletableFuture.supplyAsync(() -> /* compute value */, executor);
  }
}
