java线程中interrupt执行之后，并不能阻止线程执行，可以使用变量来控制，如下代码：

package com.qiu.lin.he;

import java.io.IOException;

public class CeShi extends Thread {
volatile boolean stop = false;

public static void main(String[] args) throws IOException,
InterruptedException {
CeShi thread = new CeShi();
System.out.println("Starting thread...");
thread.start();
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("Asking thread to stop...");

thread.stop = true;
Thread.sleep(3000);
System.out.println("Stopping application...");
}

@Override
public void run() {
while (!stop) {//当stop变量为false时，则停止
System.out.println("Thread is running...");
long time = System.currentTimeMillis();
while (System.currentTimeMillis() - time < 1000 && !stop) {
}
}
System.out.println("Thread exiting under request...");
}

}

运行结果如下：

以下为我的实现代码，可以试下：
import java.util.Date;
public class TestInterrupt {

/**
* @param args
*/
public static void main(String[] args) {
MyThread thread = new MyThread();
thread.start();
int i = 0;
while(i++<=10){ //当i=10时，终止标志设为true
thread.stopThread();
}

}

}

class MyThread extends Thread {
private boolean stopFlag = false ; //设置终止标志为false
public void run() {
while(true) {
System.out.println("===" + new Date() + "===");
try {
sleep(1000);
if(stopFlag){//当终止标志为true时，跳出循环体，线程结束
interrupt(); //当触发interrupt操作时，会
}
} catch(InterruptedException e) {
break;
}
}
}

public void stopThread(){
stopFlag = true;
}

}

catch (InterruptedException e) {
thread.interrupt();
}
应该写成：
catch (InterruptedException e) {
}
thread.interrupt();
