How can I provide a default bean implementation in Spring MVC with xml configuration?

I'm working on some old code base and it's using xml configuration.

Basically it has a basic controller named BaseController and all other controllers inherit that. Now I need to add an extra service bean which all current controllers need to use. The bean definition is like this:

<bean id="myService" class="com.myweb.MyService" scope="singleton"/>

The base controller will also have a field named MyService myService, with a null value now.

Instead of setting the property name in the xml file under each existing controller bean mapping (there are too many), how can I set the singleton MyService instance to all controllers at runtime (like a default value instead of null)?

You can autowire the bean.

Annotate your BaseController MyService field with 

@Autowired
private MyService myService;
