java8从集合中查找对象的属性 + 集合筛选功能

        // 根据流程实例ID查询已经撤销的流程
        List<String> processInstanceIds = models.stream().map(ProcessForLineScreenResponse::getInstanceId).collect(Collectors.toList());
        if (processInstanceIds.size() > 0) {
            List<String> ids = this.mapper.getStopedProcessInstanceByIds(processInstanceIds);
            // 过滤掉已撤销的流程
            models = models.stream().filter(u -> !ids.contains(u.getInstanceId())).collect(Collectors.toList());
        }
