如何在serviceImpl抛出异常

    private void checkRelationTaskList(List<DeliveryTaskDO> taskList) {        if (CollectionUtils.isNotEmpty(taskList)) {            List<String> errorList = taskList.stream()                .map(deliveryTaskDO -> String.format("%s(%s)", deliveryTaskDO.getTaskName(), deliveryTaskDO.getId()))                .collect(Collectors.toList());            String errorMessage = String.format("投放任务有引用，无法删除：%s", Joiner.on(", ").join(errorList));            throw new IllegalArgumentException(errorMessage);        }    }
