public void processFile(@PathVariable String id, @PathVariable String type, HttpServletResponse response) 
        try 
            byte[] b = null;
            ProcessDefinitionVo pd = flowableProcessDefinitionService.getById(id);
            if (pd != null) 
                if (type.equals("xml")) 
                    response.setHeader("Content-type", "text/xml;charset=UTF-8");
                    InputStream inputStream = repositoryService.getResourceAsStream(pd.getDeploymentId(), pd.getResourceName());
                    b = IoUtil.readInputStream(inputStream, "image inputStream name");
                 else 
                    response.setHeader("Content-Type", "image/png");
                    InputStream inputStream = repositoryService.getResourceAsStream(pd.getDeploymentId(), pd.getDgrmResourceName());
                    b = IoUtil.readInputStream(inputStream, "image inputStream name");
                
                response.getOutputStream().write(b);
            
         catch (Exception e) 
            LOGGER.error("ApiFlowableModelResource-loadXmlByModelId:" + e);
            e.printStackTrace();
