java - 错误 beanFactory/ApplicationContext - JAVA

Question

我正在关注 tutorial使用JAVA操作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/声明它。谁能帮我吗？

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: 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？

Answer 1

我通过替换以下内容解决了这个问题: 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");
    }
