基于Java8并行流(parallelStream)的注意点

List<OrderListVO> orderListVOS = new LinkedList<OrderListVO>();

baseOrderBillList.parallelStream().forEach(baseOrderBill -> {
   OrderListVO orderListVO = new OrderListVO();
   // 设置order中的属性

   orderListVO.setOrderbillgrowthid(baseOrderBill.getOrderbillgrowthid());
   orderListVO.setOrderbillid(baseOrderBill.getOrderbillid());
   ……
   orderListVOS.add(orderListVO);
}

List<OrderListVO> orderListVOS = Collections
.synchronizedList(new LinkedList<OrderListVO>());

List<OrderListVO> orderListVOS = orderListVOS.parallelStream()
                .sorted(Comparator.comparing(OrderListVO::getCreatetime).reversed())
                .collect(Collectors.toList());

listByPage.parallelStream().forEach(str-> {
           //使用线程安全的数据结构
           //ConcurrentHashMap
           //CopyOnWriteArrayList
           //等等进行操作
        });

  ForkJoinPool forkJoinPool = new ForkJoinPool(10);
        forkJoinPool.execute(() -> {
            listByPage.parallelStream().forEach(str -> {
                
            });
        });
