How to pass parameters dynamically to Spring beans

If i get you right, then the correct answer is to use getBean(String beanName, Object... args) method, which will pass arguments to the bean. I can show you, how it is done for Java based configuration, but you’ll have to find out how it is done for an 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?

UPDATE

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