这个章节来完成并行网关，前端无需修改，直接后端修改就可以了。

1、并行网关后端修改如下：

 String createConcurrentGatewayBuilder(String formId, JSONObject flowNode) throws InvocationTargetException, IllegalAccessException {
        //String name = flowNode.getString("nodeName");
        ParallelGateway parallelGateway = new ParallelGateway();
        String parallelGatewayId = id("parallelGateway");
        parallelGateway.setId(parallelGatewayId);
        parallelGateway.setName("并行网关");
        ddProcess.addFlowElement(parallelGateway);
        ddProcess.addFlowElement(connect(formId, parallelGatewayId));

        if (Objects.isNull(flowNode.getJSONArray("concurrentNodes"))
                && Objects.isNull(flowNode.getJSONObject("childNode"))) {
            return parallelGatewayId;
        }

        List<JSONObject> flowNodes = Optional.ofNullable(flowNode.getJSONArray("concurrentNodes")).map(e -> e.toJavaList(JSONObject.class)).orElse(Collections.emptyList());
        List<String> incoming = Lists.newArrayListWithCapacity(flowNodes.size());
        for (JSONObject element : flowNodes) {
            JSONObject childNode = element.getJSONObject("childNode");
            if (Objects.isNull(childNode)) {
                incoming.add(parallelGatewayId);
                continue;
            }
            String identifier = create(parallelGatewayId, childNode);
            if (Objects.nonNull(identifier)) {
                incoming.add(identifier);
            }
        }

        JSONObject childNode = flowNode.getJSONObject("childNode");
        if (Objects.nonNull(childNode)) {
            // 普通结束网关
            if (CollectionUtils.isEmpty(incoming)) {
                return create(parallelGatewayId, childNode);
            } else {
                // 所有 service task 连接 end parallel gateway
                childNode.put("incoming", incoming);
                FlowElement flowElement = ddBpmnModel.getFlowElement(incoming.get(0));
                // 1.0 先进行边连接, 暂存 nextNode
                JSONObject nextNode = childNode.getJSONObject("childNode");
                childNode.put("childNode", null);
                String identifier = create(incoming.get(0), childNode);
                for (int i = 1; i < incoming.size(); i++) {
                    FlowElement flowElement1 = ddBpmnModel.getFlowElement(incoming.get(i));
                    ddProcess.addFlowElement(connect(flowElement1.getId(), identifier));
                }
                // 1.1 边连接完成后，在进行 nextNode 创建
                if (Objects.nonNull(nextNode)) {
                    return create(identifier, nextNode);
                } else {
                    return identifier;
                }
            }
        }
        return parallelGatewayId;
    }

2、效果图如下：

3、生产的xml如下：
