老师,你好:
自定义异步线程池时: 下面2种方式哪个更优?有什么区别?

1. 重写springBoot默认线程池, 实现 AsyncConfiger
2. 自定义线程池配置类

@Configuration
public class PoolConfig {
    @Bean
    public Executor testExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(10);
        executor.setMaxPoolSize(20);
        executor.setQueueCapacity(20);
        executor.setKeepAliveSeconds(60);
        executor.setThreadNamePrefix("ImoocAsync_");
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        return executor;
    }
}
