Java实现异步调用的代码示例

public class MyExecutor {
    private ExecutorService executor = Executors.newCachedThreadPool() ;
    public void fun() throws Exception {
        executor.submit(new Runnable(){
            @override
                public void run() {
                    try {
                        //要执行的业务代码，我们这里没有写方法，可以让线程休息几秒进行测试
                        Thread.sleep(10000);
                        System.out.print("睡够啦~");
                    }catch(Exception e) {
                        throw new RuntimeException("报错啦！！");
                    }
                }
        });
    }
}

public class Demo{
    
    public static void main(String[] args) {
        
         MyExecutor  myExecutor = new MyExecutor();
         try {
            myExecutor.fun();
            System.our.print("你先睡着,我先回家啦~");
        }catch(Exception e) {
             throw new RuntimeException("业务程序报错啦！！");
        }
    }
}
