@Qualifier

@Qualifier decorator allows us to specify a name for a bean. This can be particularly useful when multiple beans of the same type exist, and we want to specify which bean to use in a certain scenario. In the future, this decorator will be used for a few more use cases.

Lets use the @Qualifier decorator to specify the name of a bean.

@ClawjectApplication
class Application {
  @Bean
  @Qualifier('cat')
  animal1 = new Animal('meow');

  @Bean
  @Qualifier('dog')
  animal2 = new Animal('woof');

  @PostConstruct
  postConstruct(
    cat: Animal // animal1 bean with qualifier 'cat' will be injected here
  ) {
    console.log(cat.sound);
  }
}
