我需要在bootstartup中通過Java代碼刪除工作流程。我的代碼在運行時正常工作，但是如果我在引導啓動時運行它，則會引發異常。我應該如何通過Java代碼刪除bootstartup中的工作流程？在bootstartup中通過Java代碼刪除工作流程
例如：
我-例如-context.xml中：
<bean id="my-example" class="MyExamle" init-method="init">
<property name="workflowService">
<ref bean="WorkflowService"/>
</property>
</bean>
MyExamle.java：
public class MyExamle {
...
private WorkflowService workflowService;
public void init() {
PropertyCheck.mandatory(this, "workflowService", workflowService);
AuthenticationUtil.runAs(new AuthenticationUtil.RunAsWork<Integer>() {
@Override
public Integer doWork() throws Exception {
Integer count = 0;
WorkflowDefinition reviewDef = workflowService.getDefinitionByName(
"activiti$activitiReview"
);
List<WorkflowInstance> workflowInstanceList = workflowService.getActiveWorkflows(
reviewDef.getId()
);
count = workflowInstanceList.size();
for (WorkflowInstance workflowInstance : workflowInstanceList) {
workflowService.deleteWorkflow(
workflowInstance.getId()
);
}
return count;
}
}, AuthenticationUtil.getSystemUserName());
}
...
}
這個代碼拋出異常：org.alfresco。 service.namespace.NamespaceException：名稱空間前綴wf未映射到名稱空間URI
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mrem-extention-bootstartup' defined in URL [jar:file:/C:/Alfresco/tomcat/webapps/alfresco/WEB-INF/lib/moldavia-rem.jar!/alfresco/extension/mrem-bootstartup-context.xml]: Invocation of init method failed; nested exception is org.alfresco.service.namespace.NamespaceException: Namespace prefix wf is not mapped to a namespace URI

我使用默認的「使用Activiti工作流引擎查看和批准內容」工作流程，因此數據模型定義沒問題。此外，此代碼在運行時正常工作。我嘗試使用「onBootstrap（）」，「@PostConstruct」和「init-method」，但應用程序拋出NamespaceException。猜猜，工作流模型稍後會加載，但我不知道如何列出這個事件:( – Kot4 2012-07-16 12:57:42
沒問題;哪條線會拋出異常？但是首先嚐試onBootstrap（），它也解決了我前一段時間的問題:-) – shmoula 2012-07-16 13:02:46
I同意 - 你會想使用onBootstrap（）。在引導之前，並不是所有的bean都會被定義和初始化。 – Gagravarr 2012-07-16 13:06:49
