1、自定义线程池

@Configuration
public class ThreadPoolConfig {

    public static ThreadPoolExecutor getThreadPoolExecutor() {
        int availableProcessors = Runtime.getRuntime().availableProcessors();
        return new ThreadPoolExecutor(
                availableProcessors,
                availableProcessors,
                0L,
                TimeUnit.MILLISECONDS,
                new LinkedBlockingQueue<>(9999),
                new ThreadFactoryBuilder().setNameFormat("custom-thread-pool-%d").build(),
                new ThreadPoolExecutor.CallerRunsPolicy());
    }

}

2、程序存在异常，却返回成功

写一个存在异常的程序，让其异步执行

public static final ThreadPoolExecutor CUSTOM_THREAD_POOL = ThreadPoolConfig.getThreadPoolExecutor();

/**
 * 异步执行异常测试
 */
@ApiOperation(value = "异步执行异常测试", code = 800)
@GetMapping("/asyncException")
public ResponseDat
