给线程池里面线程添加名称的4种方式
- 1、 Spring 框架提供的 CustomizableThreadFactory
- 2、Google guava 工具类 提供的 ThreadFactoryBuilder ,使用链式方法创建。
- 3、 Apache commons-lang3 提供的 BasicThreadFactory
- 4、 自定义一个ThreadFactory
1、 Spring 框架提供的 CustomizableThreadFactory
private ThreadFactory springThreadFactory = new CustomizableThreadFactory("springThread-pool-");
ThreadPoolExecutor threadPool = new ThreadPoolExecutor(
10,
30,
5,
TimeUnit.MINUTES,
new ArrayBlockingQueue<Runnable>(1000),
springThreadFactory ); //给线程池中的线程自定义名称
2、Google guava 工具类 提供的 ThreadFactoryBuilder ,使用链式方法创建。
private ThreadFactory guavaThreadFactory = new ThreadFactoryBuilder().setNameFormat("retryClient-pool-").build();
ThreadPoolExecutor threadPool = new ThreadPoolExecutor(
10,
30,
5,
TimeUnit.MINUTES,
new ArrayBlockingQueue<Runnable>(1000),
guavaThreadFactory ); //给线程池中的线程自定义名称
3、 Apache commons-lang3 提供的 BasicThreadFactory
private ThreadFactory basicThreadFactory = new BasicThreadFactory.Builder().namingPattern("basicThreadFactory-").build();
ThreadPoolExecutor threadPool = new ThreadPoolExecutor(
10,
30,
5,
TimeUnit.MINUTES,
new ArrayBlockingQueue<Runnable>(1000),
basicThreadFactory ); //给线程池中的线程自定义名称
4、 自定义一个ThreadFactory
自定义NamesThreadFactory 代码:
public class NamesThreadFactory implements ThreadFactory{
private final ThreadGroup group;
private final AtomicInteger threadNumber = new AtomicInteger(1);
private final String namePrefix;
public NamesThreadFactory(String name) {
SecurityManager s = System.getSecurityManager();
group = (s != null) ? s.getThreadGroup() : Thread.currentThread().getThreadGroup();
if (null == name || name.isEmpty()) {
name = "pool";
}
namePrefix = name + "-thread-";
}
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;
}
}
使用代码
private NamesThreadFactory namesThreadFactory = new NamesThreadFactory("namesThread-");
ThreadPoolExecutor threadPool = new ThreadPoolExecutor(
10,
30,
5,
TimeUnit.MINUTES,
new ArrayBlockingQueue<Runnable>(1000),
namesThreadFactory); //给线程池中的线程自定义名称
