由于每次上传execl数据十万条，一次批量太慢
用的是线程池+batchSave，但是事物失效，怎么办

@Before(Tx.class)
public void test1(List<TaxPayExcel> resultList){
    long begin=System.currentTimeMillis();
    ExecutorService executorService = Executors.newCachedThreadPool();
    for(int j=0;j<10;j++){
        int finalJ = j;
        executorService.execute(()->{
            List<TaxPayExcel> tempList=new ArrayList<>();
            for(int i = finalJ *3000; i<(finalJ+1)*3000; i++){
                tempList.add(resultList.get(i));
            }
            Db.batchSave(tempList,tempList.size());
        });
    }
    executorService.shutdown();
    try {
        executorService.awaitTermination(1, TimeUnit.DAYS);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    long end=System.currentTimeMillis();
    System.out.println(end-begin);
    throw new RuntimeException("");
}
