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会抛出异常。我应该怎么做才能通过 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.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());
    }
    ...
}

此代码抛出异常：org.alfresco.service.namespace.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

我认为您提供的例外与您的问题无关。检查您的数据模型定义。

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类并覆盖 onBootstrap(ApplicationEvent event) 和 onShutdown(ApplicationEvent event)。调用 init() 时可能存在未初始化的 Alfresco 系统部分。
