包路径：org.activiti.engine.RepositoryService
类名称：RepositoryService
方法名：getBpmnModel

RepositoryService.getBpmnModel介绍

[英]Returns the BpmnModel corresponding with the process definition with the provided process definition id. The BpmnModel is a pojo versions of the BPMN 2.0 xml and can be used to introspect the process definition using regular Java.
[中]使用提供的流程定义id返回与流程定义相对应的BpmnModel。BpmnModel是BPMN 2.0 xml的pojo版本，可用于使用常规Java内省流程定义。
