Autowiring two beans implementing same interface - how to set default bean to autowire?

Question

Background:

I have a Spring 2.5/Java/Tomcat application. There is the following bean, which is used throughout the application in many places

publi         


        

Answer 1

What about @Primary?

Indicates that a bean should be given preference when multiple candidates are qualified to autowire a single-valued dependency. If exactly one 'primary' bean exists among the candidates, it will be the autowired value. This annotation is semantically equivalent to the element's primary attribute in Spring XML.

@Primary
public class HibernateDeviceDao implements DeviceDao

Or if you want your Jdbc version to be used by default:

@Primary is also great for integration testing when you can easily replace production bean with stubbed version by annotating it.
