activiti 流程模型複製源碼

activiti 流程模型複製源碼

今天使用框架開發流程時，感覺從頭畫一個activiti 流程圖太麻煩了，隨即想到加個流程模型複製功能可以節省大量的開發時間。lets go 。
代碼如下：

  //activiti 流程模型複製
    @Transactional(readOnly = false)
    public Model copy(String id) throws Exception {

        Model sourceModel = this.get(id);
        ObjectNode sourceObjectNode = (ObjectNode) new ObjectMapper().readTree(repositoryService.getModelEditorSource(id));

        Model model = repositoryService.newModel();
        model.setKey(sourceModel.getKey() + "_" + IdGenerator.get());
        model.setName(sourceModel.getName()+"_copy");
        model.setCategory(sourceModel.getCategory());
        model.setVersion(1);
        repositoryService.saveModel(model);

        ObjectNode editorNode = sourceObjectNode.deepCopy();
        ObjectNode properties = objectMapper.createObjectNode();
        properties.put("process_id", model.getKey());
        properties.put("process_author", "lms");
        properties.put("name", model.getName());
        editorNode.set("properties", properties);

        repositoryService.addModelEditorSource(model.getId(), editorNode.toString().getBytes("utf-8"));

        return model;

    }
