Spring Boot Auto-configuration:
Spring Boot auto-configuration attempts to automatically configure your Spring application based on the jar dependencies that you have added.
- All auto-configuration logic is implemented in spring-boot-autoconfigure.jar.
- @ConditionalOnClass: This configuration is enabled only when these classes are available in the classpath.
- @ConditionalOnMissingBean: This bean is configured only if there is no other bean configured with the same name.

Sir what is classpath path I don't have a clear picture of this when u explain autoconfiguration

[@JavaGuides]

Classpath is location where your jar files ( contains . class files) present. Whenever you add maven dependency to pom.xml, maven will download that dependency as JAR file and add to the classpath. Spring boot app refer to the classpath where all the jars files located.
