Boots and Beans
Spring bean
A Spring bean refers to an object that’s managed by the Spring Inversion of Control (IoC) container.
@SpringBootApplication
Applying @SpringBootApplication to a Spring app’s main application class
- Enables Spring to identify the class as the configuration class that provides beans for the Spring application context
- Enables Spring to scan for and configure annotated classes as beans
- Enables Spring to configure beans based on code as well as jar dependencies
@SpringBootApplication is a compilation of the @Configuration, @EnableAutoConfiguration, and @ComponentScan annotations.
import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class ExampleApplication {public static void main(String[] args) {SpringApplication.run(ExampleApplication.class, args);}}
application context
The application context serves as a container into which Spring can inject beans.
Spring Boot
Spring Boot extends the Spring framework by enabling the autoconfiguration of Spring beans, further simplifying development.
application.properties
The application.properties file specifies the configuration properties of a Spring Boot application.
