在系统运行后,在线程快照里总是看到线程池的名字为pool-xx,这样导致很不好定位,怎么给线程池一个有意义的名字呢。参照ThreadPoolExecutor类的ThreadFactory,自己实现ThreadFactory接口,重写newThread方法即可。参考代码如下:
public class NamedThreadFactory implements ThreadFactory { private static final AtomicInteger POOL_SEQ = new AtomicInteger(1); private final AtomicInteger mThreadNum = new AtomicInteger(1); private final String mPrefix; private final boolean mDaemo; private final ThreadGroup mGroup; public NamedThreadFactory() { this("pool-" + POOL_SEQ.getAndIncrement(),false); } public NamedThreadFactory(String prefix) { this(prefix,false); } public NamedThreadFactory(String prefix,boolean daemo) { mPrefix = prefix + "-thread-"; mDaemo = daemo; SecurityManager s = System.getSecurityManager(); mGroup = ( s == null ) ? Thread.currentThread().getThreadGroup() : s.getThreadGroup(); } public Thread newThread(Runnable runnable) { String name = mPrefix + mThreadNum.getAndIncrement(); Thread ret = new Thread(mGroup,runnable,name,0); ret.setDaemon(mDaemo); return ret; } public ThreadGroup getThreadGroup() { return mGroup; } }
