将JSON结构转换为BPMN代码的具体实现方式取决于所使用的BPMN工具和库。以下是一些常用的BPMN工具和库的示例代码:
1. Camunda Modeler:
```javascript
var json = {
"id": "process",
"name": "Process",
"bpmn2:definitions": {
"bpmn2:process": {
"id": "Process_1",
"isExecutable": "true",
"bpmn2:startEvent": {
"id": "StartEvent_1",
"name": "Start"
},
"bpmn2:sequenceFlow": {
"id": "SequenceFlow_1",
"sourceRef": "StartEvent_1",
"targetRef": "Task_1"
},
"bpmn2:userTask": {
"id": "Task_1",
"name": "User Task",
"bpmn2:incoming": "SequenceFlow_1",
"bpmn2:outgoing": "SequenceFlow_2"
},
"bpmn2:sequenceFlow": {
"id": "SequenceFlow_2",
"sourceRef": "Task_1",
"targetRef": "EndEvent_1"
},
"bpmn2:endEvent": {
"id": "EndEvent_1",
"name": "End",
"bpmn2:incoming": "SequenceFlow_2"
}
},
"xmlns:bpmn2": "http://www.omg.org/spec/BPMN/20100524/MODEL"
}
};
var xml = jsonxml(json, {rootName: 'bpmn:definitions'});
var canvas = document.getElementById('canvas');
var viewer = new BpmnJS({
container: canvas
});
viewer.importXML(xml, function(err) {
if (err) {
console.log('error rendering', err);
} else {
console.log('rendered');
}
});
```
2. bpmn-moddle:
```javascript
var json = {
"id": "process",
"name": "Process",
"flowElements": [
{
"id": "StartEvent_1",
"name": "Start",
"type": "bpmn:StartEvent"
},
{
"id": "Task_1",
"name": "User Task",
"type": "bpmn:UserTask",
"incoming": [
{
"id": "SequenceFlow_1"
}
],
"outgoing": [
{
"id": "SequenceFlow_2"
}
]
},
{
"id": "EndEvent_1",
"name": "End",
"type": "bpmn:EndEvent",
"incoming": [
{
"id": "SequenceFlow_2"
}
]
}
],
"sequenceFlows": [
{
"id": "SequenceFlow_1",
"sourceRef": "StartEvent_1",
"targetRef": "Task_1"
},
{
"id": "SequenceFlow_2",
"sourceRef": "Task_1",
"targetRef": "EndEvent_1"
}
]
};
var moddle = new BpmnModdle();
moddle.fromJSON(json, function(err, bpmn) {
if (err) {
console.log('error rendering', err);
} else {
console.log('rendered', bpmn);
}
});
```
这些示例代码演示了如何使用Camunda Modeler和bpmn-moddle将JSON结构转换为BPMN。这些示例代码只是演示,实际应用中还需要根据具体的场景进行修改和定制。
