SpringBoot配置和使用多线程池的实现-创新互联

某些情况下，我们需要在项目中对多种任务分配不同的线程池进行执行。从而通过监控不同的线程池来控制不同的任务。为了达到这个目的，需要在项目中配置多线程池。

spring boot 提供了简单高效的线程池配置和使用方案。

配置

首先是配置线程池的bean交给spring 管理：

@Configuration

public class TaskExecutePool {

 @Bean(name ="threadPoolA")

public ThreadPoolTaskExecutormyTaskAsyncPool() {

ThreadPoolTaskExecutor executor =new ThreadPoolTaskExecutor();
  executor.setCorePoolSize(4);

  executor.setMaxPoolSize(8);

  executor.setQueueCapacity(100);

  executor.setKeepAliveSeconds(60);

  executor.setThreadNamePrefix("Pool-A");

  executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());

  executor.initialize();

  return executor;

 }

@Bean(name ="ThreadPoolB")

public ThreadPoolTaskExecutorAsyncPoolB() {

ThreadPoolTaskExecutor executor =new ThreadPoolTaskExecutor();

  executor.setCorePoolSize(2);

  executor.setMaxPoolSize(4);

  executor.setQueueCapacity(8);

  executor.setKeepAliveSeconds(60);

  executor.setThreadNamePrefix("Pool-B");
  //当任务数量超过MaxPoolSize和QueueCapacity时使用的策略，该策略是又调用任务的线程执行
  executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());

  executor.initialize();

  return executor;

 }

}
