多个 ThreadPoolTask​​Executers Spring Java 配置

Question

我的应用程序中需要多个任务执行器，但我没有看到如何使用 Java Config。 XML 版本很简单，但我一定在 Java Config

中遗漏了一些东西

我需要两个具有不同队列和线程池大小的不同执行器，如何使用 Java 配置来完成？

这是我的 AsyncConfig class

import org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler;
import org.springframework.aop.interceptor.SimpleAsyncUncaughtExceptionHandler;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.scheduling.annotation.AsyncConfigurer;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import java.util.concurrent.Executor;

@EnableScheduling
@EnableAsync
@Configuration
public class AsyncConfig implements AsyncConfigurer {

    @Autowired
    Environment environment;

    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(environment.getRequiredProperty("aysnc.executor.poolSize", Integer.class));
        executor.setMaxPoolSize(environment.getRequiredProperty("aysnc.executor.maxPoolSize", Integer.class));
        executor.setQueueCapacity(environment.getRequiredProperty("aysnc.executor.queueCapacity", Integer.class));
        executor.initialize();
        return executor;
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return new SimpleAsyncUncaughtExceptionHandler();
    }
}

Answer 1

我认为您可以删除接口，在标记为 @Bean(name = "nameOfExecutor") 的 JavaConfig 中定义 2 个执行器，然后根据文档在 @Async("nameOfExecutor") 中使用 bean 名称：May be used to determine the target executor to be used when executing this method, matching the qualifier value (or the bean name) of a specific Executor or TaskExecutor bean definition.

Answer 2

如果您的用户 Spring 引导您可以定义一个 bean SchedulingConfigurer。在此 bean 中，您可以覆盖方法 configureTasks。

我觉得你可以尝试设置每个任务的执行者

@Configuration
public class MySchedulingConfigurer implements SchedulingConfigurer {

    @Autowired
    @Qualifier(value="taskExecutor2")
    Executor taskExecutor2;

    @Autowired
    @Qualifier(value="taskExecutor1")
    Executor taskExecutor1;

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        if (XXXXXXXXXX) {
            taskRegistrar.setScheduler(taskExecutor1);
        } else {
            taskRegistrar.setScheduler(taskExecutor2);
        }
    }

    @Bean(destroyMethod = "shutdown",name="taskExecutor2")
    public Executor taskExecutor() {
        return Executors.newScheduledThreadPool(10);
    }

    @Bean(destroyMethod = "shutdown",name="taskExecutor1")
    public Executor taskExecutor() {
        return Executors.newScheduledThreadPool(100);
    }
}
