@Asyn使用自定义线程池

1 主类上增加启用异步注解

@SpringBootApplication
@EnableAutoConfiguration
@EnableAsync
public class Application {


    public static void main(String[] args){
        SpringApplication.run(Application.class, args);
    }
}

2 配置自己线程池（commonPoolTaskExecutor）

@Configuration
public class ExecutorConfig {


    @Bean
    public ThreadPoolTaskExecutor commonPoolTaskExecutor(){
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(5);
        executor.setMaxPoolSize(10);
        executor.setQueueCapacity(100);
        executor.setKeepAliveSeconds(300);
        executor.setThreadNamePrefix("CommExecutor-");
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        return executor;
    }
}

3 定义异步方法

由于spring代理原理，异步方法需要写到单独一个类，由其它类从外部来调用，否则调用本类的@Async不起效的

@Component
public class SmsAlarmTemplate {

    @Async("commonPoolTaskExecutor")// 使用自定义的线程池
    public void fun(){
// 异步方法
    }
}
