java TheadLocal 多线程资源使用

线程处理资源类：

package org.shefron.fc.thread.threadlocal;

import java.util.HashMap;

public class HandleThead extends Thread {
	private HashMap map = null;

	public HandleThead(HashMap hashMap) {
		map = hashMap;
	}
	@Override
	public void run() {
		super.run();
		RegisterManager.getRegisterManager().startRegister(map);
		if (RegisterManager.getRegisterManager().getRegister() != null){
			System.out.println("呵呵,有啊");
		}
	}
	public void print(){
		if (RegisterManager.getRegisterManager().getRegister() == null){
			System.out.println("没有了");
		}
	}

}

多线程资源管理类：

package org.shefron.fc.thread.threadlocal;

import java.util.HashMap;

public class RegisterManager {

	private ThreadLocal<HashMap> localRegister = new ThreadLocal<HashMap>();
	private static RegisterManager manager = new RegisterManager();

	private RegisterManager(){
	}

	public static RegisterManager getRegisterManager(){
		return manager;
	}

	public void startRegister(HashMap infoMap){
		this.localRegister.set(infoMap);
	}

	public HashMap getRegister(){
		return this.localRegister.get();
	}

}

主方法测试类：

package org.shefron.fc.thread.threadlocal;

import java.util.HashMap;


public class TestThreadLocal {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		HashMap map = new HashMap();
		map.put("hehe", "haha");

		RegisterManager.getRegisterManager().startRegister(map);


		HandleThead handle = null;
		for (int i=1;i<4;i++){
			handle = new HandleThead(new HashMap());
			//子线程
			handle.start();

			if(handle != null){
				//此方法位于主线程
				handle.print();
			}
		}

		System.out.println(RegisterManager.getRegisterManager().getRegister());


	}

}
