Question

我跟随tutorial使用JAVA操纵Alfresco上的nodeRef和内容。但是当我尝试定义serviceRegistry时，

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

beanFactory未初始化。我已经尝试了很多声明，但我无法正确初始化/声明这一点。任何人都可以帮助我吗？

我试试：

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

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

网络的客户端的应用程序-context.xml中： https://github.com/Alfresco/community-edition/blob/master/projects/web-client/config/alfresco/web-client-application-context.xml

ERROR：

org.springframework.beans.factory.BeanCreationException：错误使用名称＆＃39; GlobalAuthenticationFilter＆＃39;创建bean在课堂上定义路径资源[alfresco / web-client-application-context.xml]：不能解析对bean＆＃39; Authentication＆＃39;的引用设置bean属性时＆＃39; applicationContextManager＆＃39 ;;嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有 bean名为＆＃39; Authentication＆＃39;已定义

另一种方式？我该如何解决这个问题？

我通过替换它来解决它：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");
    }

错误beanFactory / ApplicationContext - JAVA
