大家好，又见面了，我是你们的朋友全栈君。

一、线程池配置

1、ThreadPoolConfig

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import java.util.concurrent.Executor;
import java.util.concurrent.ThreadPoolExecutor;
@Configuration
public class ThreadPoolConfig { 

private final static int AVAILABLE_PROCESSOR = Runtime.getRuntime().availableProcessors();
/** * 通用线程池配置 */
@Bean("taskPoolExecutor")
public Executor taskExecutor() { 

ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
//设置线程池参数信息
taskExecutor.setCorePoolSize(6);
taskExecutor.setMaxPoolSize(6*2);
taskExecutor.setQueueCapacity(12);
taskExecutor.setKeepAliveSeconds(60);
taskExecutor.setThreadNamePrefix("taskPoolExecutor--");
taskExecutor.setWaitForTasksToCompleteOnShutdown(true);
taskExecutor.setAwaitTerminationSeconds(60);
//修改拒绝策略为使用当前线程执行
taskExecutor.setRejectedExecutionHandler(new ThreadPoolExecutor.AbortPolicy());
//初始化线程池
taskExecutor.initialize();
return taskExecutor;
}
/** * 发送短信线程池 * @return */
@Bean("sendSmsThreadPool")
public Executor sendSmsThreadPool() { 

ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
//设置线程池参数信息
taskExecutor.setCorePoolSize(AVAILABLE_PROCESSOR);
taskExecutor.setMaxPoolSize(AVAILABLE_PROCESSOR + 1);

taskExecutor.setKeepAliveSeconds(20);
taskExecutor.setThreadNamePrefix("sendSmsThreadPool--");
taskExecutor.setWaitForTasksToCompleteOnShutdown(true);
taskExecutor.setAwaitTerminationSeconds(60);
//修改拒绝策略为使用当前线程执行
taskExecutor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
//初始化线程池
taskExecutor.initialize();
return taskExecutor;
}
/** * 发送邮件线程池 * @return */
@Bean("sendEmailThreadPool")

//设置线程池参数信息
taskExecutor.setCorePoolSize(AVAILABLE_PROCESSOR);

}
