在启动时通过Java代码删除工作流
我需要在启动时通过Java代码删除工作流。我的代码在运行时正常工作，但如果我在启动时运行它，它会引发异常。如何通过Java代码在启动时删除工作流
例如：
我的示例上下文。xml:
<bean id="my-example" class="MyExamle" init-method="init">
<property name="workflowService">
<ref bean="WorkflowService"/>
</property>
</bean>
MyExamle。爪哇：
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());
}
...
}
此代码引发异常：org。露天的。服务名称空间。NamespaceException:命名空间前缀wf未映射到命名空间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

我认为你提供的例外情况与你的问题无关。检查数据模型定义
在所有情况下——回到你的问题——尝试使用onBootstrap（）而不是init（），只需扩展AbstractLifecycleBean类并重写onBootstrap（ApplicationEvent事件）和onShutton（ApplicationEvent事件）。调用init（）时，Alfresco系统可能存在未初始化的部分
