10. Idempotent
11. spring boot in-memory database
12. spring boot actuator
13. equals, hash code , y we want to override
14. what is use @EnableAutoconfiguration
@EnableAutoConfiguration annotation tells Spring Boot to "guess" how you will want to configure Spring, based on the jar dependencies that you have added. For example, If HSQLDB is on your classpath, and you have not manually configured any database connection beans, then Spring will auto-configure an in-memory database.@ComponentScan tells Spring to look for other components, configurations, and services in the specified package. Spring is able to auto scan, detect and register your beans or components from pre-defined project package. If no package is specified current class package is taken as the root package.
Actually the
@SpringBootApplication annotation is equivalent to using @Configuration, @EnableAutoConfiguration and @ComponentScan with their default attributes.
