## **BPMN2.0元素** ##

事件（普通启动、定时启动、错误启动、普通结束、错误结束）

网关－独占网关（唯一网关）、并行网关、包含网关

活动 - 用户任务、事件任务、服务任务、脚本任务

组 - 泳道、子流程

线 - 顺序

## **引擎** ##

配置：activiti.cfg.xml

## **模型** ##

*  模型创建ProcessDefinationController

try {
             BpmServiceUtils.getRepositoryService().addModelEditorSource(entity.getId(), modeljson.toString().getBytes("utf-8"));
          } catch (UnsupportedEncodingException e) {
             
          }

*  模型保存

Model model = repositoryService.getModel(modelId);
    
    
       resultNode.put("update_time", model.getLastUpdateTime().toString());
       repositoryService.addModelEditorSource(model.getId(), values
             .getFirst("json_xml").getBytes("utf-8"));
       //生成png图片
       /*PNGTranscoder transcoder = new PNGTranscoder();
       // Setup output
       ByteArrayOutputStream outStream = new ByteArrayOutputStream();
       TranscoderOutput output = new TranscoderOutput(outStream);
    
       // Do the transformation
       transcoder.transcode(input, output);
       final byte[] result = outStream.toByteArray();
       repositoryService.addModelEditorSourceExtra(model.getId(), result);
       outStream.close();*/
    
       JsonNode editorNode = new ObjectMapper().readTree(values.getFirst(
             "json_xml").getBytes("utf-8"));
       BpmnJsonConverter jsonConverter = new BpmnJsonConverter();
       BpmnModel bpmModel = jsonConverter.convertToBpmnModel(editorNode);
       resultNode=validate(bpmModel,resultNode);
