Solon v3.0.0

Async 调度(异步)

</> markdown

引入调度相关的插件

<dependency>
    <groupId>org.noear</groupId>
    <artifactId>solon-scheduling</artifactId>
</dependency>

启用异步调度

@EnableAsync
public class DemoApp{
    public void static void main(String[] args){
        Solon.start(DemoApp.class, args);
    }
}

定义异步执行的服务

//定义个服务
@Component
public class AsyncTask {
    //会被异步运行(提交到异步执行器运行)//不要返回值(返回也拿不到)
    @Async
    public void test(String hint){
        System.out.println(Thread.currentThread().getName());
    }
}

应用示例

//应用
@Controller
public class DemoController{
    @Inject
    AsyncTask asyncTask;
    
    @Mapping("/test")
    public void test(){
        //调用
        asyncTask.test("test");
    }
}

自定义异步执行器

@Component
public class AsyncExecutorImpl implements AsyncExecutor {
    //定义个线程池
    ExecutorService executor = ...;
    
    @Override
    public Future submit(Invocation inv, Async anno) throws Throwable{
        if (inv.method().getReturnType().isAssignableFrom(Future.class)) {
            return (Future) inv.invoke();
        } else {
            return executor.submit(() -> {
                try {
                    return inv.invoke();
                } catch (Throwable e) {
                    throw new RuntimeException(e);
                }
            });
        }
    }
}
