Tell us what are some of the important Spring annotations which you have used?

Submitted by: Muhammad

Some of the Spring annotations that I have used in my project are:

☛ @Controller – for controller classes in Spring MVC project.

☛ @RequestMapping – for configuring URI mapping in controller handler methods. This is a very important annotation, so you should go through Spring MVC RequestMapping Annotation Examples

☛ @ResponseBody – for sending Object as response, usually for sending XML or JSON data as response.

☛ @PathVariable – for mapping dynamic values from the URI to handler method arguments.

☛ @Autowired – for autowiring dependencies in spring beans.

☛ @Qualifier – with @Autowired annotation to avoid confusion when multiple instances of bean type is present.

☛ @Service – for service classes.

☛ @Scope – for configuring scope of the spring bean.

☛ @Configuration, @ComponentScan and @Bean – for java based configurations.

AspectJ annotations for configuring aspects and advices, @Aspect, @Before, @After, @Around, @Pointcut etc.
