Spring Auto-Wiring Using Annotations with Qualifiers

Concept Overview Typically in Spring, dependency injection is achieved using bean , constructor-arg and property tags within XML configuration file. However, in large applications, the number of beans increases and the corresponding XML written to configure the numerous beans will become very large and unwieldly. Spring provides a feature called ‘Auto-Wiring’ that minimizes the XML … Read more
