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());	}}
