如何在 Spring Boot 中创建不同的 ThreadPoolTaskExecutor? [英] How to create a different ThreadPoolTaskExecutor in Spring Boot?
本文介绍了如何在 Spring Boot 中创建不同的 ThreadPoolTaskExecutor?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我现在使用 @EnableAsync
和 @Async
注释在 Spring Boot 中使用多线程.我有服务 A(快)和服务 B(慢).
I am now using @EnableAsync
and @Async
annotation to use multithreaded in Spring Boot. I have service A(fast) and service B(slow).
如何为它们设置不同的池?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.
How can I set different pool for them? So when there are lots of calls for B, the application can still handle service A in a different pool from B.
@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;
}
}
推荐答案
首先,你可以定义你的线程池执行器并使用它们作为 bean 像这样配置它们 -
First of all, you can define your thread pool executor and use them as a configure them as beans like this -
@Configuration
public class ThreadConfig {
@Bean
public TaskExecutor executorA() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(4);
executor.setMaxPoolSize(4);
executor.setThreadNamePrefix("default_task_executor_thread");
executor.initialize();
return executor;
}
@Bean
public TaskExecutor executorB() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(4);
executor.setMaxPoolSize(4);
executor.setThreadNamePrefix("executor-B");
executor.initialize();
return executor;
}
}
之后,您可以像这样在方法级别指定执行器 -
After that, you can specify your executor on method level like this -
@Async("executorA")
public void methodWithVoidReturnType(String s) {
.....
}
@Async("executorA")
public Future<String> methodWithSomeReturnType() {
...
try {
Thread.sleep(5000);
return new AsyncResult<String>("hello world !!!!");
} catch (InterruptedException e) {
...
}
return null;
}
