I have few problems during upgrade Spring version in application.

In legacy code we are using BeanFactoryLocator in order to get main context (registry) in which defined all other contexts. After I am getting BeanFactoryReference by name.

BeanFactoryLocator beanFactoryLocator = DefaultLocatorFactory.getInstance(k.getSelector() // name of the main context, kind of registry for other contexts);
            BeanFactoryReference factoryRef = beanFactoryLocator.useBeanFactory(k.getFactoryName() // name of the concrete context xml);
            BeanFactory factory = new FactoryWrapper(factoryRef.getFactory(), k.getFactoryName());
return factory;

In Spring 5.0 there is no BeanFactoryLocator, DefaultLocatorFactory objects. How I can implement it another way?

There is an interesting discussion here about the outdated mechanism of using beanFactoryLocator, Juergen Hoeller recommended to use

a custom static holder class for one or more ApplicationContexts, keyed by something that has a meaning for your use case, and with a proper lifecycle.
