What is the process of automatic configuration in Sprin…

The process of auto-configuration in Spring Boot is as follows:

1. When Spring Boot starts up, it loads all auto-configuration classes configured in the META-INF/spring.factories file under the classpath.
2. Auto-wiring classes will determine whether to automatically wire based on conditions such as the existence of a particular class or bean, or the presence of a specific configuration.
3. The eligible auto-wired classes will be instantiated and registered into the Spring container.
4. The Spring container automatically injects dependencies of other Beans based on the configuration of the autowired class, using Spring’s dependency injection mechanism.
5. If there are multiple matching classes for auto-configuration, Spring Boot will choose one based on the specified priority in the configuration.
6. Once the automatic assembly is complete, you can inject the automatically assembled bean into other beans for use through the @Autowired annotation or other methods.

In general, the automatic configuration process of Spring Boot determines whether to perform automatic configuration based on conditions. If the conditions are met, the automatic configuration class is instantiated and registered in the Spring container, then dependency injection is performed based on the configuration.
