//实例化BpmnModel对象
BpmnModel bpmnModel=new BpmnModel();
//开始节点的属性
StartEvent startEvent=new StartEvent();
startEvent.setId("start1shareniu");
startEvent.setName("start1shareniu");
//普通的UserTask节点
UserTask userTask=new UserTask();
userTask.setId("userTask1shareniu");
userTask.setName("userTask1shareniu");
//结束节点属性
EndEvent endEvent=new EndEvent();
endEvent.setId("endEventshareniu");
endEvent.setName("endEventshareniu");
//连线信息
List<SequenceFlow> sequenceFlows=new ArrayList<SequenceFlow>();
List<SequenceFlow> toEnd=new ArrayList<SequenceFlow>();
SequenceFlow s1=new SequenceFlow();
s1.setId("starttouserTask");
s1.setName("starttouserTask");
s1.setSourceRef("start1shareniu");
s1.setTargetRef("userTask1shareniu");
sequenceFlows.add(s1);
SequenceFlow s2=new SequenceFlow();
s2.setId("userTasktoend");
s2.setName("userTasktoend");
s2.setSourceRef("userTask1shareniu");
s2.setTargetRef("endEventshareniu");
toEnd.add(s2);
startEvent.setOutgoingFlows(sequenceFlows);
userTask.setOutgoingFlows(toEnd);
userTask.setIncomingFlows(sequenceFlows);
endEvent.setIncomingFlows(toEnd);
//Process对象
Process process=new Process();
process.setId("process1");
process.addFlowElement(startEvent);
process.addFlowElement(s1);
process.addFlowElement(userTask);
process.addFlowElement(s2);
process.addFlowElement(endEvent);
bpmnModel.addProcess(process);

//BpmnModel转化xml

//将上面的对象转化为标准的xml代码如下所示：

//bpmnModel 转换为标准的bpmn xml文件

BpmnXMLConverter bpmnXMLConverter=new BpmnXMLConverter();

byte[] convertToXML = bpmnXMLConverter.convertToXML(bpmnModel);

String bytes=new String(convertToXML);

System.out.println(bytes);

ProcessValidatorFactory processValidatorFactory=new ProcessValidatorFactory();

ProcessValidator defaultProcessValidator = processValidatorFactory.createDefaultProcessValidator();

//验证失败信息的封装ValidationError

List<ValidationError> validate = defaultProcessValidator.validate(bpmnModel);

System.out.println(validate.size());

//需要说明的是：ValidationError封装的是验证信息，如果size为0说明，bpmnmodel正确，大于0,说明自定义的bpmnmodel是错误的，不可以使用的。
