错误 beanFactory/ApplicationContext - JAVA

Question

我正在跟随 tutorial 使用 JAVA 操作 nodeRef 和 A​​lfresco 上的内容。但是当我尝试定义 serviceRegistry,

 ServiceRegistry serviceRegistry = (ServiceRegistry) beanFactory.getBean(ServiceRegistry.SERVICE_REGISTRY);
   

beanFactory 未初始化。我已经尝试了很多声明，但我不能 initialise/declare 正确。谁能帮帮我？

我试试：

ApplicationContext appContext = new ClassPathXmlApplicationContext("alfresco/web-client-application-context.xml");

ServiceRegistry serviceRegistry = (ServiceRegistry) appContext.getBean(ServiceRegistry.SERVICE_REGISTRY);

web-client-application-context.xml: https://github.com/Alfresco/community-edition/blob/master/projects/web-client/config/alfresco/web-client-application-context.xml

错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'GlobalAuthenticationFilter' defined in class path resource [alfresco/web-client-application-context.xml]: Cannot resolve reference to bean 'Authentication' while setting bean property 'applicationContextManager'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'Authentication' is defined

另一种方式？我该如何解决这个问题？

我用这个替代解决了这个问题：ServiceRegistry serviceRegistry = (ServiceRegistry) beanFactory.getBean(ServiceRegistry.SERVICE_REGISTRY);

为此：

protected ServiceRegistry getServiceRegistry() {
        ProcessEngineConfigurationImpl config = Context.getProcessEngineConfiguration();
        if (config != null) {
            // Fetch the registry that is injected in the activiti spring-configuration
            ServiceRegistry registry = (ServiceRegistry) config.getBeans().get(ActivitiConstants.SERVICE_REGISTRY_BEAN_KEY);

            if (registry == null) {
                throw new RuntimeException("Service-registry not present in ProcessEngineConfiguration beans, expected ServiceRegistry with key" + ActivitiConstants.SERVICE_REGISTRY_BEAN_KEY);
            }

            return registry;
        }
        throw new IllegalStateException("No ProcessEngineCOnfiguration found in active context");
    }
