Convert XML bean definition with parent to Java with annotations

I have an application using a framework that provides certain Spring beans via XML files in the framework. The configuration of my application is currently done partly in XML but mostly with Spring annotations.

Some of the XML bean definitions have parents referring to beans supplied by the framework, e.g.

<bean id="MyBean" parent="FrameworkBean">
    <property name="context">
        <map merge="true">
            <entry key="SomeKey" value-ref="SomeValue" />
        </map>
    </property>
</bean>

FramwworkBean is defined in an XML file in the framework. There is a chain of bean inheritance. At each step some entries are added to the context:

<bean id="FrameworkBean" parent="AbstractBean">
   <map merge="true">...

<bean id="AbstractBean" abstract="true" class="ClassWithContext"/>

I understand the result of all this is construction of a ClassWithContext instance with a map containing all the entries up the chain. Is it possible to write Java code to do the same, without duplicating code from the framework XML files?

@Bean("MyBean") ClassWithContext myBean() {
    return ??? // code that uses "FrameworkBean" somehow
}

The XML bean definition has no dependency on the type of AbstractBean. If MyBean can be created by Java code, can that code be written to be equally type-agnostic? Or should I just leave this in XML?

If your "FrameworkBean" is not abstract bean you can try the following:

@Bean
public SomeType myBean(@Qualifier("FrameworkBean") FrameworkBeanType frameworkBean) {
    SomeType type = getSomeType();
    type.setFrameworkBean(frameworkBean);
    return type;
}
