activiti 获取流程图

activiti 获取流程图

activiti在部署的时候将 bgmn和生成的图片 png，存放到ACT_GE_BYTEARRAY表中，需要在显示流程图的时候，直接从数据库查出即可

@Test    public void viewImage() throws IOException{        Deployment deployment = repositoryService.createDeploymentQuery().list().get(0);        String id = deployment.getId();        List<String> names = repositoryService.getDeploymentResourceNames(id);        String imageName = "";        for (String name : names) {            System.out.println("name:"+name);            if(name.indexOf(".png")>=0){                imageName = name;            }        }        if(imageName!=""){            File file = new File("c://"+imageName);            FileUtils.copyInputStreamToFile(repositoryService.getResourceAsStream(id, imageName), file);            file.createNewFile();        }    }
