页面代码介绍：
springboot静态文件处理
@Configuration public class WebConfig implements WebMvcConfigurer { @Override public void addResourceHandlers(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
@RestController public class Test01Controller { @RequestMapping("/editor/stencilset") public String 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 class ModelTest { @RequestMapping("create") public void createModel(HttpServletRequest request, HttpServletResponse response){ try{ String modelName = "modelName6"; String modelKey = "modelKey66"; String description = "modelKey666"; ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RepositoryService repositoryService = processEngine.getRepositoryService(); ObjectMapper objectMapper = new ObjectMapper(); 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 void saveModel(@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 = new TranscoderInput(svgStream);
PNGTranscoder transcoder = new PNGTranscoder();
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
TranscoderOutput output = new TranscoderOutput(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"} ) public ObjectNode 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); } } return modelNode; }
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) throws Exception {
Model modelData = repositoryService.getModel("40001");
ObjectNode modelNode = (ObjectNode) new ObjectMapper().readTree(repositoryService.getModelEditorSource(modelData.getId()));
byte[] bpmnBytes = null;
BpmnModel model = new BpmnJsonConverter().convertToBpmnModel(modelNode);
bpmnBytes = new BpmnXMLConverter().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
