1，先建一个Map

/**

* 创建一个Map用于存放线程id对象集合，主要是用于到达岗亭之后扫码付费，如果人工收费就需要关闭线程，key是停车记录Id，

*/

public static MapMAPTHREAD = new HashMap();

2.建一个线程类继承Runnable

/**

* 轮询查询网上支付结果

* @author Administrator

*

*/

@Component

public class PollingSearch implements Runnable{

private String flag;

private ParkingRecord parkingRecord;

// @Autowired

// private OnlinePaymentService onlinePaymentService;

//@Autowired

//private CameraLogic cameraLogic;

@Override

public void run() {

try {

CameraLogic cameraLogic = (CameraLogic) SpringUtil.getObject("cameraLogic");

OnlinePaymentService onlinePaymentService = (OnlinePaymentService) SpringUtil.getObject("onlinePaymentServiceImpl");

while(CommonUtil.MAPTHREAD.get(flag).equals("true")) {

Thread.sleep(5000);

}

} catch (Exception e) {

e.printStackTrace();

}

}

public void setFlag(String flag) {

this.flag = flag;

}

public ParkingRecord getParkingRecord() {

return parkingRecord;

}

public void setParkingRecord(ParkingRecord parkingRecord) {

this.parkingRecord = parkingRecord;

}

public String getFlag() {

return flag;

}

spring容器中无法自动注入，所以用这两句代码获取，springUtil可参考我的另一篇文章 spring ioc容器管理

CameraLogic cameraLogic = (CameraLogic) SpringUtil.getObject("cameraLogic");

OnlinePaymentService onlinePaymentService = (OnlinePaymentService) SpringUtil.getObject("onlinePaymentServiceImpl");

重要的代码在这

while(CommonUtil.MAPTHREAD.get(flag).equals("true")) {

上面代码在根据map中判断了是否执行轮询，当为true时才执行

下面开启线程

final String parkRecordId = oldRecord.getId();

final ParkingRecord parkingRecord = oldRecord;

//将账单id放进map中，为了等待支付完成时可以根据停车记录id找到该账单后删除

CommonUtil.PAYMENTRECORDMAP.put(parkRecordId, paymentRecord.getId());

CommonUtil.MAPTHREAD.put(parkRecordId, "true");

PollingSearch pollingSearch = new PollingSearch();

pollingSearch.setParkingRecord(parkingRecord);

pollingSearch.setFlag(parkRecordId);

Thread thread = new Thread(pollingSearch);

thread.start();

在需要关闭线程的时候

final String parkingRecordId = parkingRecord.getId();

CommonUtil.MAPTHREAD.put(parkingRecordId,"false");

CommonUtil.MAPTHREAD.remove(parkingRecordId);

这样子就可以给各个线程手动关闭了
