activiti獲取流程圖實例

本文實例講述了activiti獲取流程圖的方法，具體操作步驟如下：

1.發布流程代碼如下:

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

2.根據key獲取流程圖代碼如下:

ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery() 
                            .processDefinitionKey("expense") 
                            .singleResult(); 
 
String diagramResourceName = processDefinition.getDiagramResourceName(); 
InputStream imageStream = repositoryService.getResourceAsStream(processDefinition.getDeploymentId(), diagramResourceName); 
 

3.如果想流程發布的時候不生成流程圖，需要進行如下配置：

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