1. 异常捕获

public class LoggerThreadFactory  implements ThreadFactory {  
   
 @Override  
 public Thread newThread(Runnable r) {  
   Thread t = new Thread(r);  
   t.setUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler(){  
      @Override  
      public void uncaughtException(Thread t, Throwable e) {  
        LoggerFactory.getLogger(t.getName()).error(e.getMessage(), e);  
      }  
   });  
 return t;  
 }  
}  

设置线程名，计数等

public WorkerThreadFactory implements ThreadFactory {  
   
 private int counter = 0;  
 private String prefix = "";  
   
 public WorkerThreadFactory(String prefix) {  
   this.prefix = prefix;  
 }  
   
 public Thread newThread(Runnable r) {  
   return new Thread(r, prefix + "-" + count++);  
 }  
}  

设置thread属性

public class DaemonThreadFactory implements ThreadFactory {  
    public Thread newThread(Runnable r) {  
       Thread t = new Thread(r);  
       t.setDaemon(true);  
       return t;  
    }  
}  

当线程放入池里，会调用ThreadFactory的newThread()进行封装。
