spring管理不了thread中的事务。

java主类由spring管理，主类中调用thread，目标是：thread中逻辑有异常后，所有事务回滚。

下面是thread的实现，必须开启一个新的事务，单独管理线程中的逻辑

class BusiOrderSaveThread extends Thread{
  BusiOrder busiOrder;
  LoginOpr loginOpr;
  CountDownLatch countdown ;
  IBusiPubOrder busiPubOrder;
  private Map<String,String> map;
  private boolean flag;
  /**
   * @param bo
   * @param loginOpr
   * @throws IOException
   * @throws IOException
   */
public BusiOrderSaveThread(BusiOrder busiOrder, LoginOpr loginOpr,CountDownLatch countdown,IBusiPubOrder busiPubOrder,Map<String,String> map,boolean flag) throws IOException {
   super();
   this.busiOrder=busiOrder;
   this.loginOpr = loginOpr;
   this.countdown = countdown;
   this.busiPubOrder = busiPubOrder;
   this.map = map;
   this.flag = flag;
  }
  @SuppressWarnings("unchecked")
  @Override
  public void run() {

   long id = Thread.currentThread().getId();
   DataSourceTransactionManager transactionManager =
    (DataSourceTransactionManager) SpringContextFactory.getBean("transactionManager");
   DefaultTransactionDefinition def = new DefaultTransactionDefinition();
   def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRES_NEW); //事物隔离级别
   TransactionStatus status = transactionManager.getTransaction(def); //获得事务状态
   try {
    if(flag){
     this.busiPubOrder.saveOrder(this.busiOrder, this.loginOpr);
     String a =null;
     if(a.equals("1"));
    }
    transactionManager.commit(status);

   } catch (Exception e) {
    flag =false;
    if(e instanceof BusiException){
     BusiException ex = (BusiException)e;
     this.map.put("false"+id,ex.getErrMsg());
    }else{
        this.map.put("false"+id,e.getMessage());
    }
    transactionManager.rollback(status);
   }finally{
                this.countdown.countDown();
    }
   }
   }

主类调用：

//深度拷贝
     BusiOrder bo = new BusiOrder();
     bo=(BusiOrder)JavaTool.cloneObject(busiOrder);
     ThreadExcutorSingleton.service.execute(new BusiOrderSaveThread(bo,loginOpr,countdown,busiPubOrder,map,flag));
    }
    countdown.await();
    //获取异常信息 begin add by zhaozj
    Set<String> keys = map.keySet();
    List<String> errorList = new ArrayList<String>();
    if(keys!=null&&keys.size()>0){
     for(String key:keys){
      errorList.add(map.get(key));
     }
     throw new BusiException("成员管理保存订单异常："+errorList.get(0));
    }
