How to implement a mechanism for creating objects marked with the @Bean annotation inside your own framework based on Spring?

To implement a mechanism for creating objects annotated with @Bean inside your own Spring-based framework, you need to:

1. Scan classes for methods with @Bean annotation. Usually, this is done using reflection, scanning configuration classes.

2. Create and register beans in the container. For each method with @Bean, invoke it and register the returned object as a bean in the context.

3. Manage dependencies. If the @Bean method takes parameters, resolve them from the container to inject dependencies.

4. Ensure scope and lifecycle management. Support scopes (singleton, prototype, etc.) and manage bean lifecycle.

Example of a simplified implementation in Java:

public class MyBeanFactory {
    private Map<String, Object> beans = new HashMap<>();

    public void registerBeans(Object config) throws Exception {
        Class<?> clazz = config.getClass();
        for (Method method : clazz.getDeclaredMethods()) {
            if (method.isAnnotationPresent(Bean.class)) {
                Object bean = method.invoke(config);
                beans.put(method.getName(), bean);
            }
        }
    }

    public Object getBean(String name) {
        return beans.get(name);
    }
}

Thus, your framework should scan configuration classes, find methods with @Bean, invoke them, and store the created objects for further use.
