activiti获取流程图实例

本文实例讲述了activiti获取流程图的方法，具体操作步骤如下：

1.发布流程代码如下:

repositoryService.createDeployment()
 .name("expense-process.bar")
 .addClasspathResource("org/activiti/expenseProcess.bpmn20.xml")
 .addClasspathResource("org/activiti/expenseProcess.png")
 .deploy();

2.根据key获取流程图代码如下:

ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
                            .processDefinitionKey("expense")
                            .singleResult();

String diagramResourceName = processDefinition.getDiagramResourceName();
InputStream imageStream = repositoryService.getResourceAsStream(processDefinition.getDeploymentId(), diagramResourceName);

3.如果想流程发布的时候不生成流程图，需要进行如下配置：

<property name="createDiagramOnDeploy" value="false" />
