How to create bean without XML configuration in Spring / How to create bean in Spring using Annotations

Create a class which you want to get as a bean, say a user and annotate it with @Configuration as:

public class User {
	@Value("codippa")//initialize the value of this field
	private String name;
	private String country;
	public String getName() {
		return name;
	public void setName(String name) { = name;
	public String getCountry() {
		return country;
	public void setCountry(String country) { = country;


[sc name=”AD1″ ]

Create a main class to get this bean. This class uses AnnotationConfigApplicationContext as ApplicationContext implementation:

public class Main {
	public static void main(String[] args) {
		ApplicationContext context = new AnnotationConfigApplicationContext(User.class);
		User user = (User)context.getBean("user");

This will print codippa and India.

[sc name=”AD2″ ]

There is another way of creating bean without XML configuration which is using @Component annotation. Refer Other ways of creating bean in Spring.

Let’s tweak in :

  1. You can also define packages where your beans reside instead of class names in AnnotationConfigApplicationContext as AnnotationConfigApplicationContext(“com.codippa”).
  2. @Configuration annotated class may also contain other bean definitions whose getter methods should be annotated with @Bean such as :
    public class User {
    		public ExternalUser getUser() {
    		return new ExternalUser();

    The bean with name “extUser” can be retrieved using getBean method of ApplicationContext as in above example.

  3. [sc name=”Leaderboard-ad” ]
  4. @Value is used to provide value to class fields. The value may be given there only or may be fetched from an external property file using ${propertyName}.
  5. @Configurationis a class-level annotation. Applying it to some other level (such as a method or a field) will generate a compiler error The annotation @Configuration is disallowed for this location.
