flowable流程中心设计之审核按钮扩展(十一)

 

说明

为了满足不同的流程节点可以操作的按钮不同,支持对接方动态配置

如 办理 、驳回、 抄送 、挂起流程 、流程终止 可以控制某些节点可操作按钮

同监听器一样

针对模型设计提交的json改动

针对部署改动

1.针对json转运行时PBMN对象处

com.biaoguoworks.flowable.custom.convert.CustomUserTaskJsonConverter#convertJsonToElement

2.针对BPMN对象转XML处

com.biaoguoworks.flowable.custom.convert.CustomUserTaskXMLConverter#writeAdditionalAttributes

跟监听器不同的监听器类型我们是根据type区分。但是针对属性我们是扩展属性所以我们要自定义一个TASK继承原有TASK进行封装我们的自定义属性

com.biaoguoworks.flowable.custom.model.CustomUserTask

执行阶段改动

针对XML转为BPMN对象

com.biaoguoworks.flowable.custom.convert.CustomUserTaskJsonConverter#convertJsonToElement

使用

com.biaoguoworks.flowable.center.service.impl.CenterFormServiceImpl#getTaskForm

后续我们就可以通过任务找到流程定义 通过api将流程定义xml转换成运行时对象则可以拿到我们自定义button信息

 

ProcessDefinition processDefinition=processEngine.getRepositoryService().createProcessDefinitionQuery().processDefinitionId(task.getProcessDefinitionId()).singleResult();
BpmnModel bpmnModel = flowBpmnModelService.getBpmnModelByProcessDefId(task.getProcessDefinitionId());
Process process = bpmnModel.getProcessById(processDefinition.getKey());
FlowElement taskFlowElement = process.getFlowElement(task.getTaskDefinitionKey());
if (!(taskFlowElement instanceof CustomUserTask)) {
    return null;
}
CustomUserTask customUserTask=(CustomUserTask)taskFlowElement;
getTaskFormResDto.setButtons(ButtonParse.INSTANCE.getProcessButtons(customUserTask.getButtons()));
