RepositoryService.getDecisionDiagram介绍

[英]Gives access to a deployed decision diagram, e.g., a PNG image, through a stream of bytes.
[中]通过字节流访问已部署的决策图，例如PNG图像。

@Override

 DecisionDefinition definition = engine.getRepositoryService().getDecisionDefinition(decisionDefinitionId);
 InputStream decisionDiagram = engine.getRepositoryService().getDecisionDiagram(decisionDefinitionId);
 if (decisionDiagram == null) {
  return Response.noContent().build();
 } else {
  String fileName = definition.getDiagramResourceName();
  return Response.ok(decisionDiagram).header("Content-Disposition", "attachment; filename=" + fileName)
    .type(ProcessDefinitionResourceImpl.getMediaTypeForFileSuffix(fileName)).build();
 }
