In general, I recommend the use of JSR 330 annotation for DI, the annotation is as capable as Spring's and if you want you can also mix and match this with Spring's and annotations.Ĥ. The third most common difference between and annotation is that the former is Spring specific while the latter is the standard for Dependency Injection, specified in JSR-330. The first and most important difference between is that the is only available from Spring 3.0 onwards, so if you want to use annotation-driven dependency injection in Spring 2.5 then you have to use the The second difference between these two annotations is that, unlike Spring's the does not require the 'required' attribute.ģ.
#AUTOWIRED JAVA CODE#
When you use the JPA annotations like your code will not only work on Hibernate but also on other ORM tools and frameworks like Eclipse TopLink.ītw, like all similar things in the world, even though both and serve the same purpose there are a couple of differences between them, let's examine them brieflyġ. If you have worked with Hibernate and JPA in past then JSR-330 annotation is nothing but like JPA annotations which standardize the Object-Relational mapping across the framework. Good knowledge of essential Spring annotations is very important for a hands-on developer. and bean declared to be auto-wired using will work in both Google Guice and Spring framework, and potentially any other DI container which supports JSR-330 annotations. You can potentially avoid that development effort by using standard annotations specified by JSR-330 e.g. Since Spring is not the only framework that provides dependency injection, in the future if you change your container and moves to another DI framework like Google Guice, you need to reconfigure your application. The also serves the same purpose, but the main difference between them is that is a standard annotation for dependency injection and is spring specific.
You can annotate fields and constructor using to tell Spring framework to find dependencies for you. If you don't know, autowiring is a process on which the Spring framework figure out the dependencies of a Spring bean, instead of you, a developer, explicitly specifying them in the application context file. What is the difference between and annotation in Spring is one of the frequently asked Spring questions on Java interviews? Since everybody is now moved or moving to annotation-driven and Java configuration in Spring, this question has become even more important for prospective candidates looking for a Java web development job using the Spring framework. The annotation is used for auto-wiring in the Spring framework.
