API alfresco repository version 6.X or 7.X 应用上下文的初始化问题

Question

When I want to initialize the application context of the Alfresco repository version 6.X or 7.X (I have tested the latest version 7.78 and the version 6.57), I have these errors:

Configuration problem: Failed to import bean definitions from URL location [classpath:alfresco/application-context-core.xml]

Offending resource: class path resource [alfresco/application-context.xml]; nested exception is org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from URL location [classpath:alfresco/core-services-context.xml]

Offending resource: class path resource [alfresco/application-context-core.xml]; nested exception is org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 587 in XML document from class path resource [alfresco/core-services-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 587; columnNumber: 107; cvc-datatype-valid.1.2.1: 'cm:constraintRegistry' is not a valid value for 'NCName'.

My code is very simple:

public class AlfrescoApp {

    public static void main(String[] args) {

        try {
            ServiceRegistry serviceRegistry = null;
            ApplicationContext context = null;
            context = new ClassPathXmlApplicationContext("alfresco/application-context.xml");

            serviceRegistry = (ServiceRegistry) context.getBean(ServiceRegistry.SERVICE_REGISTRY);
            AuthenticationUtil.setAdminUserAsFullyAuthenticatedUser();

            NodeService nodeService = serviceRegistry.getNodeService();

        } catch (Exception e) {
            System.err.println(e.getMessage());
        }
    }

}

and this is the content of my POM.xml file:

I don't know why I have these errors with this above code. Please could you help me to solve this problem?

Answer 1

The problem is that you mixed up various versions of the Spring framework jar-s in your pom.xml. To fix this, simply remove all unnecessary dependencies from your pom.xml and don't use old versions of Spring, like that "all-in-one" 2.5 version.

The old Spring versions seem not to allow ":" in bean identifiers ( NCName type forbids this, to be concrete). This is the case of one of the beans defined inside "alfresco/core-services-context.xml" which is mentioned in the errors output you supplied:

<bean id="cm:constraintRegistry" class="org.alfresco.repo.dictionary.constraint.ConstraintRegistry" />

If you look at the pom.xml of the alfresco-repository-7.78.jar, you will see it relies on Spring version 5.1.8.RELEASE - to avoid problems, try to use the very same version in your project as well.
