自定义线程工厂的代码
import java.util.concurrent.ThreadFactory;
import java.util.concurrent.atomic.AtomicInteger;
public class CustomThreadFactory implements ThreadFactory {
private static final AtomicInteger poolNumber = new AtomicInteger(1);
private final ThreadGroup group;
private final AtomicInteger threadNumber = new AtomicInteger(1);
private final String namePrefix;
public CustomThreadFactory(String namePrefix) {
SecurityManager s = System.getSecurityManager();
this.group = (s != null) ? s.getThreadGroup() :
Thread.currentThread().getThreadGroup();
if (namePrefix == null || namePrefix.isEmpty()) {
this.namePrefix = "pool-" +
poolNumber.getAndIncrement() +
"-thread-";
} else {
if (!namePrefix.endsWith("-")) {
this.namePrefix = namePrefix + "-";
} else {
this.namePrefix = namePrefix;
}
}
}
public CustomThreadFactory() {
SecurityManager s = System.getSecurityManager();
group = (s != null) ? s.getThreadGroup() :
Thread.currentThread().getThreadGroup();
namePrefix = "pool-" +
poolNumber.getAndIncrement() +
"-thread-";
}
@Override
public Thread newThread(Runnable r) {
Thread t = new Thread(group, r,
namePrefix + threadNumber.getAndIncrement(),
0);
if (t.isDaemon())
t.setDaemon(false);
if (t.getPriority() != Thread.NORM_PRIORITY)
t.setPriority(Thread.NORM_PRIORITY);
return t;
}
}
使用自定义的线程工厂
return new ThreadPoolExecutor(3,
3,
60,
TimeUnit.SECONDS,
new LinkedBlockingQueue<>(20),
new CustomThreadFactory("mdc-thread-pool"));
