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