springboot异步执行

使用@EnableAsync开启异步执行

在接口方法上使用@Async注解进行标注，该接口是一个异步接口

自定义异步线程执行器

@Configuration
public class CustomAsyncConfigurer implements AsyncConfigurer {

    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(4);
        executor.setMaxPoolSize(20);
        executor.setQueueCapacity(20);
        executor.setKeepAliveSeconds(60);
        executor.setThreadNamePrefix("myThreadPool-");
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return new AsyncUncaughtExceptionHandler() {
            @Override
            public void handleUncaughtException(Throwable ex, Method method, Object... params) {
                System.out.println("出现异常");
                ex.printStackTrace();
            }
        };
    }
}
