Accessing source code for Spring Annotations

Where can I see the source code behind the @Service or org.springframework.stereotype.Service in the Spring framework?

For Example if you want to find the logic for @Autowired in Spring Boot.

Right Click on the pom.xml, Select Maven->Download Resources.

Now in the external libraries the @Autowired annotation is defined in the org.springframework.beans.factory.annotation package. The source file is typically named Autowired.java.

The logic for this annotation is found in the same folder.

Look into classes like AutowiredAnnotationBeanPostProcessor and DefaultListableBeanFactory. These classes are part of the Spring container and are involved in the process of detecting and injecting dependencies.

If you are using IDE, to check @Service implementation you can press Ctrl and click on this annotation. org.springframework.stereotype.Service interface will be opened in this case.

Annotations themselves do not carry implementation logic, just some simple attributes. The framework (Spring in our case) just checks for the existence of annotations (i.e instances of an annotation class like Service) on our classes and then acts accordingly. For example, if it sees a Service present, it will instantiate our class as a bean and manage that bean.
