There are three different ways to configure Spring Bean:-
1 XML Configuration: This is the most popular configuration and we can use bean element in context file to configure a Spring Bean.
For example:
<bean name="myBean" class="com.test.spring.beans.MyBean"></bean>
2 Java Based Configuration: If you are using only annotations, you can configure a Spring bean using @Bean annotation. This annotation is used with @Configuration classes to configure a spring bean. Sample configuration is:
@Configuration
@ComponentScan(value="com.test.spring.main")
public class MyConfiguration {
@Bean
public MyService getService(){
return new MyService();
}}
3 Annotation Based Configuration: We can also use @Component, @Service, @Repository and @Controller annotations with classes to configure them to be as spring bean. For these, we would need to provide base package location to scan for these classes.
For example:
<context:component-scan base-package="com.test.spring" />
