activiti7根据xml字符串进行流程部署

try {
    //获取流程XML
    XMLInputFactory factory = XMLInputFactory.newFactory();
    Reader reader = new StringReader('xml 字符串');
    XMLStreamReader streamReader = factory.createXMLStreamReader(reader);
    BpmnXMLConverter converter = new BpmnXMLConverter();
    BpmnModel bpmnModel = converter.convertToBpmnModel(streamReader);


    //1.创建ProcessEngine对象
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

    //2.得到RepositoryService实例
    RepositoryService repositoryService = processEngine.getRepositoryService();

    //3.进行部署
    Deployment deployment = repositoryService.createDeployment()//创建Deployment对象
            .name('name')
            .key('key')
            .category('category')

} catch (Exception e) {
    e.printStackTrace();
