我有一个java程序,需要很长时间才能编译。
出于测试目的,如果编译需要很长时间,我想终止该程序并重新启动它。
这是我的代码的简化版本:
public class Main {
public static void main(String[] args) {
Thread foo = new Thread(new Foo());
while (true) {
foo.start();
while (true) {
if (needRestart()) {
foo.interrupt();
break;
}
}
}
}
}
foo.java 看起来有点像这样:
public class Foo implements Runnable {
// some code
public void run () {
try {
while (!Thread.currentThread().isInterrupted()) {
// some code
}
} catch(InterruptedException ex) {
Thread.currentThread().interrupt();
}
}
}
问题是程序崩溃并抛出IllegalThreadStateException
如果您需要完整的代码,这里是:full code
最佳答案
不要在 while(true)
循环中启动 foo 线程。 Thread
在其生命周期中只能启动一次。
将 foo.start();
移至 while(true)
上方
引用oracle文档页面关于Thread类start()
方法
public void start()
Causes this thread to begin execution; the Java Virtual Machine calls the run method of this thread.
The result is that two threads are running concurrently: the current thread (which returns from the call to the start method) and the other thread (which executes its run method).
It is never legal to start a thread more than once. In particular, a thread may not be restarted once it has completed execution.
关于java - Thread.interrupt 上的 IllegalThreadStateException,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/32782867/
