页面代码介绍：

springboot静态文件处理

@Configurationpublic class WebConfig implementsWebMvcConfigurer {

@Overridepublic voidaddResourceHandlers(ResourceHandlerRegistry registry){

registry.addResourceHandler("/html/**").addResourceLocations("classpath:/html/");

registry.addResourceHandler("/diagram-viewer/**").addResourceLocations("classpath:/html/");

registry.addResourceHandler("/editor-app/**").addResourceLocations("classpath:/html/");

registry.addResourceHandler("/js/**").addResourceLocations("classpath:/js/");

registry.addResourceHandler("/css/**").addResourceLocations("classpath:/css/");

}

}

获取json数据的请求

@RestControllerpublic classTest01Controller {

@RequestMapping("/editor/stencilset")publicString test01(){

InputStream stream=this.getClass().getClassLoader().getResourceAsStream("stencilset.json");try{return IOUtils.toString(stream,"utf-8");

}catch(Exception e){

}return null;

}

}

在线设计流程新建model

@Controller

@RequestMapping("model")public classModelTest {

@RequestMapping("create")public voidcreateModel(HttpServletRequest request, HttpServletResponse response){try{

String modelName= "modelName6";

String modelKey= "modelKey66";

String description= "modelKey666";

ProcessEngine processEngine=ProcessEngines.getDefaultProcessEngine();

RepositoryService repositoryService=processEngine.getRepositoryService();

ObjectMapper objectMapper= newObjectMapper();

ObjectNode editorNode=objectMapper.createObjectNode();

editorNode.put("id", "canvas");

editorNode.put("resourceId", "canvas");

ObjectNode stencilSetNode=objectMapper.createObjectNode();

stencilSetNode.put("namespace", "http://b3mn.org/stencilset/bpmn2.0#");

editorNode.put("stencilset", stencilSetNode);

Model modelData=repositoryService.newModel();

ObjectNode modelObjectNode=objectMapper.createObjectNode();

modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME, modelName);

modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION,1);

modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION, description);

modelData.setMetaInfo(modelObjectNode.toString());

modelData.setName(modelName);

modelData.setKey(modelKey);//保存模型

repositoryService.saveModel(modelData);

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

response.sendRedirect(request.getContextPath()+ "/html/modeler.html?modelId=" +modelData.getId());

}catch(Exception e){

}

}

}

画流程图保存请求

@RequestMapping("/model/{modelId}/save")

@ResponseStatus(HttpStatus.OK)public voidsaveModel(@PathVariable String modelId, HttpServletRequest req, HttpServletResponse resp) {try{

Model model= this.repositoryService.getModel(modelId);

ObjectNode modelJson= (ObjectNode)this.objectMapper.readTree(model.getMetaInfo());

modelJson.put("name", req.getParameter("name"));

modelJson.put("description",req.getParameter("description"));

model.setMetaInfo(modelJson.toString());

model.setName(req.getParameter("name"));this.repositoryService.saveModel(model);this.repositoryService.addModelEditorSource(model.getId(), (req.getParameter("json_xml")).getBytes("utf-8"));

InputStream svgStream= new ByteArrayInputStream((req.getParameter("svg_xml")).getBytes("utf-8"));

TranscoderInput input= newTranscoderInput(svgStream);

PNGTranscoder transcoder= newPNGTranscoder();

ByteArrayOutputStream outStream= newByteArrayOutputStream();

TranscoderOutput output= newTranscoderOutput(outStream);

transcoder.transcode(input, output);byte[] result =outStream.toByteArray();

System.out.println(new String(result,"utf-8"));this.repositoryService.addModelEditorSourceExtra(model.getId(), result);

outStream.close();

}catch(Exception var11) {

LOGGER.error("Error saving model", var11);throw new ActivitiException("Error saving model", var11);

}

}

流程图查看的请求

@RequestMapping(

value= {"/model/{modelId}/json"},

method={RequestMethod.GET},

produces= {"application/json"}

)publicObjectNode getEditorJson(@PathVariable String modelId) {

ObjectNode modelNode= null;

Model model= this.repositoryService.getModel(modelId);if (model != null) {try{if(StringUtils.isNotEmpty(model.getMetaInfo())) {

modelNode= (ObjectNode)this.objectMapper.readTree(model.getMetaInfo());

}else{

modelNode= this.objectMapper.createObjectNode();

modelNode.put("name", model.getName());

}

modelNode.put("modelId", model.getId());

ObjectNode editorJsonNode= (ObjectNode)this.objectMapper.readTree(new String(this.repositoryService.getModelEditorSource(model.getId()), "utf-8"));

modelNode.put("model", editorJsonNode);

}catch(Exception var5) {

LOGGER.error("Error creating model JSON", var5);throw new ActivitiException("Error creating model JSON", var5);

}

}returnmodelNode;

}

流程图保存成功以后这张表会有数据

流程图部署以后会出现bomn结尾的文件，

部署流程的请求，根据modelId

@RequestMapping("/model/test02")public void test02(Object obj) throwsException {

Model modelData= repositoryService.getModel("40001");

ObjectNode modelNode= (ObjectNode) newObjectMapper().readTree(repositoryService.getModelEditorSource(modelData.getId()));byte[] bpmnBytes = null;

BpmnModel model= newBpmnJsonConverter().convertToBpmnModel(modelNode);

bpmnBytes= newBpmnXMLConverter().convertToXML(model);

String processName= modelData.getName() + ".bpmn";

Deployment deployment=repositoryService.createDeployment()

.name(modelData.getName()).addString(processName,new String(bpmnBytes,"UTF-8"))

.deploy();

}

根据这个表的key进行流程启动，指定审批人

随意写了一些demo。。。。

重点步骤 就是新建model,保存提交部署流程，启动流程指定审批人，审批提交
