How to pass parameters dynamically to Spring beans

Question

I am new to Spring.

This is the code for bean registration:

Answer 1

If i get you right, then the correct answer is to use #getBean(String beanName, Object... args) which will pass arguments to bean. I can show you, how it is done for java-based configuration, but you'll have to find how it is done for xml based configuration.

@Configuration
public class ApplicationConfiguration {

  @Bean
  @Scope("prototype") //As we want to create several beans with different args, right?
  String hello(String name) {
    return "Hello, " + name;
  }
}

//and later in your application

AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(ApplicationConfiguration.class);
String helloCat = (String) context.getBean("hello", "Cat");
String helloDog = (String) context.getBean("hello", "Dog");

Is this what are you looking for?

Upd. This answer gets too much upvotes and nobody looks at my comment. Even though it's a solution to problem, it is considered as spring anti-pattern and you shouldn't use it! There are several different ways to do things right using factory, lookup-method, etc..
