1、转bpmn流程图接口
java
/**
* 转为bpmn xml格式
* @param processModel
* @throws IOException
*/
@PostMapping("/ddtobpmnxml")
public Result<?> ddToBpmnXml(@RequestBody ProcessModel processModel) {
try {
BpmnModel bpmnModel = processModel.toBpmnModel();
return Result.OK(new String(new BpmnXMLConverter().convertToXML(bpmnModel)));
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException("创建失败: e=" + e.getMessage());
}
}
2、toBpmnModel()方法
java
public BpmnModel toBpmnModel() {
BpmnModel bpmnModel = new BpmnModel();
// 命名空间
bpmnModel.setTargetNamespace("https://flowable.org/bpmn20");
// 创建一个流程
Process process = new Process();
// 设置流程的id
process.setId(this.getCode());
// 设置流程的name
process.setName(this.getName());
// 设置流程的文档
process.setDocumentation(this.getRemark());
// 递归构建所有节点
Node node = this.getProcess();
List<FlowElement> flowElementList = node.convert();
for (FlowElement flowElement : flowElementList) {
process.addFlowElement(flowElement);
}
// 设置流程
bpmnModel.addProcess(process);
// 自动布局
new BpmnAutoLayout(bpmnModel).execute();
return bpmnModel;
}
3、前端调用接口
javascript
const converterBpmn = () => {
const processModel = {
code: pCode.value,
name: pName.value,
icon: {
name: 'el:HomeFilled',
color: '#409EFF'
},
process: props.process,
enable: true,
version: 1,
sort: 0,
groupId: '',
remark: ''
}
ddToBpmnXml(processModel).then(res => {
console.log("ddToBpmnXml res",res)
processView.title = pName.value
processView.index = pCode.value
processView.xmlData = res.result
processView.open = true
})
}
