java 实现timeout 的问题

[lovingpig520]

代码里有一个调用其他模块的方法， 但是那个方法有时候会需要很长时间， 想实现一个timeout

创建了如下代码：
package com.timeout;

import java.util.Date;
import java.util.concurrent.Callable;
import java.util.concurrent.FutureTask;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.TimeoutException;

public class TimeOutExample {
public static void print(){
int i = 0;
while(i == 0){

}

}
public static void main(String[] args) throws Exception {

Callable reservationTask = new Callable() {
public Object call() throws InterruptedException {
String s = "";

//put JCO call here
print();

return "task has runned";
}
};

final FutureTask future = new FutureTask(reservationTask);
Thread th = new Thread() {
public void run() {
future.run();
}

};

System.out.println("Start");
long start = new Date().getTime();
th.start();

try {


String result = (String)future.get(2, TimeUnit.SECONDS);
System.out.println(result);
System.out.println("end");
} catch (TimeoutException e) {
System.out.println("time out");
future.cancel(true);

e.printStackTrace();
} finally {
long end = new Date().getTime();
System.out.println("total run time" + (end - start) + "millisecond");
}
}
}

代码中　虽然throw了　timeoutexception, 但是并没用结束print方法的执行。　问下这种情况print方法调用结束了么

问题补充　如果print是一个数据库的调用，　在线程timeout的时候和数据库的连接　能中止么？

有高手帮忙解答下么

future.getTimeout(long time,TimeUnit unit);
