spingboot异常线程

自定义线程池

import org.apache.tomcat.util.threads.ThreadPoolExecutor;
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;

@Configuration
@EnableAsync
public class MyExecutePoll {
    @Bean("myAsyncPool")
    public Executor myAsyncPool() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(50);
        executor.setMaxPoolSize(60);
        executor.setQueueCapacity(100);
        // 活跃时间
        executor.setKeepAliveSeconds(300);
        // 线程名字前缀
        executor.setThreadNamePrefix("MyExecutor-");
        //设置线程池关闭的时候等待所有任务都完成再继续销毁其他的Bean,使异步线程的销毁优先于Redis等其他处理报错
        executor.setWaitForTasksToCompleteOnShutdown(true);
        //设置线程池中任务的等待时间，如果超过这个时候还没有销毁就强制销毁，以确保应用最后能够被关闭，而不是阻塞住
        executor.setAwaitTerminationSeconds(600);
        // setRejectedExecutionHandler：当pool已经达到max size的时候，如何处理新任务
        // CallerRunsPolicy：不在新线程中执行任务，而是由调用者所在的线程来执行
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }
}

实现spring框架

import java.util.concurrent.Executor;
import java.util.concurrent.Executors;
import org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler;
import org.springframework.aop.interceptor.SimpleAsyncUncaughtExceptionHandler;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.AsyncConfigurer;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.SchedulingConfigurer;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.scheduling.config.ScheduledTaskRegistrar;
@Configuration
public class TaskConfig {
    @Configuration
    @EnableAsync
    public static class AsyncTaskConfig implements AsyncConfigurer{
        @Override
        public Executor getAsyncExecutor() {
            ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
            taskExecutor.setCorePoolSize(5);
            taskExecutor.setAllowCoreThreadTimeOut(true);
            taskExecutor.setMaxPoolSize(15);
            taskExecutor.initialize();
            return taskExecutor;
        }
        @Override
        public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
            return new SimpleAsyncUncaughtExceptionHandler();
        }
    }
    @Configuration
    @EnableScheduling
    public class ScheduleTaskConfig implements SchedulingConfigurer{
        @Override
        public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
            taskRegistrar.setScheduler(Executors.newScheduledThreadPool(10));
        }
    }
}

实现异步的方法，在方法上加注解

@Async("myAsyncPool")
