Using autowiring mechanism i am planning to establish relationships among the object.

if i annote a property with "@autowired" then should i have to declare the corresponding bean in applicationcontext.xml file.

please let me know.

No, you shouldn't. Also understand that by using @Autowire, you are not defining relationships in your objects. The relationship already exists via composition. @Autowire is just injecting one object into another object.

If you are just using @Autowired and not any @Components, then the base beans still need to be declared in your xml.

so


In order to get the ARepositoryImpl to be injected into AServiceImpl both need <bean> tags.



But the repository will be automatically injected into the service class.

If you have



Then the only thing you need in the xml is the context:component-scan tag to tell Spring which package to scan for @Component annotations. @Repository extends @Component so @Repository is an @Component.
