package com.example;import java.util.Random;public class App {        public static class MyRunnable1 implements Runnable {        //ThreadLocal是一個線程局部變數        private ThreadLocal<String> threadlocal             = new ThreadLocal<String>();         @Override        public void run() {            //threadlocal 包含方法：            //set:建立一個執行緒區域變數            //remove:移除該本地變數            //get:擷取該本地變數的值            //在hibernate中被用於本地session管理                        threadlocal.set("Name:"+new Random().nextInt(10));            try {                Thread.sleep(2000);            } catch (InterruptedException e) {                e.printStackTrace();            }            System.out.println(Thread.currentThread().getName() + " : " + threadlocal.get());        }    }     public static void main(String[] args) {        MyRunnable1 r = new MyRunnable1();        Thread t1 = new Thread(r,"thread1");        Thread t2 = new Thread(r,"thread2");        t1.start();        t2.start();    }}
