code: @Override
  	public synchronized void releaseAllThriftSocket() {
  		if (selfMap == null || selfMap.isEmpty())
  			return;
  		ThriftSocket socket;
  		for (Entry<String, SimpleSocketPoolImpl> entry : selfMap.entrySet()) {
  			SimpleSocketPoolImpl self = entry.getValue();
  			for (byte i = 0; i < size; i++) {
  				socket = self.socketPool.get(new Byte(i));
  				try {
  					socket.close();
  					self.socketStatusArray[i] = Boolean.FALSE;
  				} catch (Exception e) {
  					log.error(e.getMessage());
  				}
  			}
  		}
  	}
docs: 回收所有ThriftSocket连接
