Activiti: 三种部署方式和几种启动方式

三种部署：
1.自动部署: <property name="deploymentResources" value="classpath*:/bpmn/*.bpmn"/>

    <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
        <property name="dataSource" ref="dataSource"/>
        <property name="deploymentResources" value="classpath*:/bpmn/*.bpmn"/>
        <property name="transactionManager" ref="transactionManager"/>
        <property name="databaseSchemaUpdate" value="true"/>
        <property name="jobExecutorActivate" value="false"/>
        <property name="processDefinitionCacheLimit" value="10"/>
        <property name="activityFontName" value="${diagram.activityFontName}"/>
        <property name="labelFontName" value="${diagram.labelFontName}"/>
    </bean>

2.手动部署：

repositoryService.createDeployment()
                .addClasspathResource("bpmn/MyProcess.bpmn")
                .deploy();

3. 使用web modeler保存后，从数据库部署

    @RequestMapping("/startModel")
    public ModelAndView startModel(@RequestParam("id") String id) {
        System.out.println("id=" + id);
        Deployment deployment = null;
        try {
            Model modelData = repositoryService.getModel(id);
            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() + ".bpmn20.xml";

            deployment = repositoryService.createDeployment()
                    .name(modelData.getName())
                    .addString(processName, new String(bpmnBytes))
                    .deploy();

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


        String url = "redirect:/a/list.do";
        return new ModelAndView(url);
    }

几种启动方式
processDefinitionId：这个参数的值可以通过repositoryService.createProcessDefinitionQuery()方法查询，对应数据库：ACT_RE_PROCDEF；每次部署一次流程定义就会添加一条数据，同名的版本号累加。
ACT_RE_PROCDEF：业务流程定义数据表ID_：流程ID，由“流程编号:流程版本号:自增长ID ” 组成
建议使用startProcessInstanceByKey，特殊情况需要使用以往的版本选择使用startProcessInstanceById。

1. 根据key启动

ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("myProcess", variables);
        StartFormData formData = formService.getStartFormData(processInstance.getProcessDefinitionId());

2. 启动表单流程

Map<String, String> properties = new HashMap<String, String>();
        ProcessInstance processInstance = formService.submitStartFormData(ProcessDefinitionId, properties);
