匿名内部类快速重写方法及异步线程传递ThreadLocal方案

public class DemoMain {
	static ThreadLocal<String> local = new ThreadLocal<>();
	public static void main(String[] args) {
			local.set("HH");
	
		ThreadPoolExecutor poolExecutor = new ThreadPoolExecutor(1, 2, 20, 
				TimeUnit.SECONDS, 
				new ArrayBlockingQueue<>(1),
				Executors.defaultThreadFactory(),
				new ThreadPoolExecutor.CallerRunsPolicy()) {
			@Override
			public void execute(Runnable command) {
				// 目的:异步线程传递ThreadLoad
				String string = local.get();
				super.execute(()-> {
					local.set(Thread.currentThread().getName()+":"+string);
					command.run();
					local.remove();
				});
			}
		};
		for(int i=1; i<=4; i++) {
			poolExecutor.execute(()->{
				try {
					Thread.sleep(1000);
				} catch (InterruptedException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				System.out.println(Thread.currentThread().getName());
				System.out.println(local.get());
			});
		}
		poolExecutor.shutdown();
		// 其它类
		Studen studen = new Studen() {
			@Override
			public void doSomething() {
				System.out.println("befor");
				super.doSomething();
				System.out.println("after");
			}
			
		};
		studen.doSomething();
	}
}

其它类:

public class Studen {
	
	private  String name;
	
	public Studen() {}
	
	public void doSomething() {
		System.out.println("Studen hhh");
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}

结果:
pool-1-thread-2
pool-1-thread-2:HH
main
main:HH
befor
Studen hhh
after
pool-1-thread-1
pool-1-thread-1:HH
pool-1-thread-2
pool-1-thread-2:HH
