java - 如何在 Spring Boot 中创建不同的 ThreadPoolTask​​Executor？

Question

这个问题在这里已经有了答案:





How to use multiple threadPoolExecutor for Async Spring

我现在正在使用 @EnableAsync和 @Async在 Spring Boot 中使用多线程的注解。我有服务 A(快)和服务 B(慢)。

如何为他们设置不同的池？因此，当有大量对 B 的调用时，应用程序仍然可以在与 B 不同的池中处理服务 A。

@Configuration
@EnableAsync
public class ServiceExecutorConfig implements AsyncConfigurer {

    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
        taskExecutor.setCorePoolSize(30);
        taskExecutor.setMaxPoolSize(40);
        taskExecutor.setQueueCapacity(10);
        taskExecutor.initialize();
        return taskExecutor;

    }
}

@Bean(name = "threadPoolExecutor")
public Executor getAsyncExecutor() {
    ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
    executor.setCorePoolSize(7);
    executor.setMaxPoolSize(42);
    executor.setQueueCapacity(11);
    executor.setThreadNamePrefix("threadPoolExecutor-");
    executor.initialize();
    return executor;
}

@Bean(name = "ConcurrentTaskExecutor")
public TaskExecutor taskExecutor2 () {
    return new ConcurrentTaskExecutor(
            Executors.newFixedThreadPool(3));
}

@Override
@Async("threadPoolExecutor")
public void createUserWithThreadPoolExecutor(){
    System.out.println("Currently Executing thread name - " + Thread.currentThread().getName());
    System.out.println("User created with thread pool executor");
}

@Override
@Async("ConcurrentTaskExecutor")
public void createUserWithConcurrentExecutor(){
    System.out.println("Currently Executing thread name - " + Thread.currentThread().getName());
    System.out.println("User created with concurrent task executor");
}
