    Spring JavaConfig is a product of the Spring community that provides a pure-Java approach to configuring the Spring IoC Container. It thus helps avoid using XML configurations. The advantages of using JavaConfig are

    The advantages of JavaConfig are

    Object-oriented configuration. Because configurations are defined as classes in JavaConfig, users can take full advantage of object-oriented features in Java. One configuration class may subclass another, overriding its @Bean methods, etc.

    Reduced or eliminated XML configuration. The benefits of externalized configuration based on the principles of dependency injection have been proven. However, many developers would prefer not to switch back and forth between XML and Java. JavaConfig provides developers with a pure-Java approach to configuring the Spring container that is conceptually similar to XML configuration. It is technically possible to configure the container using only JavaConfig configuration classes, however in practice many have found it ideal to mix-and-match JavaConfig with XML.

    Type-safe and refactoring-friendly. JavaConfig provides a type-safe approach to configuring the Spring container. Thanks to Java 5.0's support for generics, it is now possible to retrieve beans by type rather than by name, free of any casting or string-based lookups.
