# `Spring boot`异步任务

全局要加上 @EnableAsync注解

定义一个接口 service 一定要加 @Async

public interface Service {
    @Async
    ListenableFuture<String> hello(String name);
}

实现接口ServiceImpl

@Component
public class ServiceImpl implements Service {
    @Override
    public ListenableFuture<String> hello(String name) {
        return new AsyncResult("hello" + name);
    }
}

调用

 ConfigurableApplicationContext context = SpringApplication.run(DemoApplication.class, args);
 Service bean = context.getBean(Service.class);
 ListenableFuture<String> hello = bean.hello("li si");
 hello.addCallback(System.out::println, System.out::println);
