 asyncTool: 解决任意的多线程并行、串行、阻塞、依赖、回调的并行框架，可以任意组合各线程的执行顺序，带全链路执行结果回调。多线程编排一站式解决方案。来自于京东主App后台。

/*** 批量更新用户（使用京东AsyncTool）** @param idList*/public void batchUpdateAsyncTool(List<Long> idList) {Boolean resultBoolean = processOrderAsyncTool(idList);if (resultBoolean) {System.out.println("所有都执行完毕");}}

@Transactional(rollbackFor = Exception.class)public Boolean processOrderAsyncTool(List<Long> idList) {List<WorkerWrapper> workerWrapperList = new ArrayList<>();for (int i = 0; i < idList.size(); i++) {UserServiceUpdateAsyncTool userServiceUpdateAsyncToolObject = new UserServiceUpdateAsyncTool();WorkerWrapper<Long, Boolean> workerWrapper = new WorkerWrapper.Builder<Long, Boolean>().id("wrapper" + idList.get(i)).worker(userServiceUpdateAsyncToolObject).callback(userServiceUpdateAsyncToolObject).param(idList.get(i))//1+1.build();workerWrapperList.add(workerWrapper);}try {//3个WorkerWrapper一起begincom.jd.platform.async.executor.Async.beginWork(1000, asyncExecutor, workerWrapperList);} catch (ExecutionException | InterruptedException e) {e.printStackTrace();}workerWrapperList.stream().forEach(workerWrapper -> {System.out.println("workResult:" + workerWrapper.getWorkResult());if ("EXCEPTION".equals(workerWrapper.getWorkResult().getResultState().name())) {if (workerWrapper.getWorkResult().getEx() instanceof BusinessException) {throw new BusinessException(workerWrapper.getWorkResult().getEx().getMessage());} else {throw new RuntimeException(workerWrapper.getWorkResult().getEx().getMessage());}}});return Boolean.TRUE;}

}

运行结果：

{"success": false,"code": "505","message": "出现了2异常","data": null
}

入参：[1,2,3,4,5]

运行结果，2、3没有更新，更新了1、4、5
