java - 错误beanFactory/ApplicationContext-JAVA

我正在遵循tutorial来使用JAVA在Alfresco上操作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，但无法正确初始化/声明。谁能帮我？

我尝试：

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：错误
  在类中创建名称为“ GlobalAuthenticationFilter”的bean
  路径资源[alfresco / web-client-application-context.xml]：无法
  设置bean属性时解析对bean'Authentication'的引用
  'applicationContextManager';嵌套异常为
  org.springframework.beans.factory.NoSuchBeanDefinitionException：否
  定义了名为“身份验证”的bean


另一种方式？我该如何解决？

最佳答案

我用以下替代方法解决了它：ServiceRegistry serviceRegistry = (ServiceRegistry) beanFactory.getBean(ServiceRegistry.SERVICE_REGISTRY);

为了这：

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");
    }
