What is Spring Boot, and how does it differ from the Spring framework?
Spring Boot is a framework that simplifies the development of Spring-based applications. It provides a number of features that make it easier to create stand-alone, production-grade applications, such as:
Auto-configuration: Spring Boot automatically configures many of the Spring features that you would typically need to configure manually.
Starter dependencies: Spring Boot provides starter dependencies that make it easy to add common features to your application, such as web development, data access, and messaging.
Embedded servers: Spring Boot provides embedded servers, such as Tomcat and Jetty, so you don't need to configure a separate web server.
Metrics and health checks: Spring Boot provides metrics and health checks that you can use to monitor your application.
How do you configure a database connection in Spring Boot?
There are two ways to configure a database connection in Spring Boot:
Using the @Configuration class: This is a more advanced way to configure a database connection. You can create a @Configuration class and specify the connection properties in the class. Spring Boot will then use the @Configuration class to configure the database connection.
Once you have configured the database connection, you can use it in your Spring Boot application using Hibernate / JPA or even simpler JdbcTemplate.

How do you implement caching in Spring Boot?
Configure a cache manager: Spring Boot provides a default cache manager, but you can also define a custom cache manager. To use the default cache manager, no further configuration is required. However, if you want to define a custom cache manager, create a bean of type CacheManager in your configuration class:
@Configuration
public class CacheConfig {
@Bean
public CacheManager cacheManager() {
// Define and configure your cache manager here
}
}
Add caching annotations to your methods: To enable caching for a specific method, use annotations such as @Cacheable, @CachePut, or @CacheEvict on the method. For example:
@Service
public class YourService {
@Cacheable("yourCacheName")
public String getCachedData(String key) {
// This method will be cached based on the cache name and the key parameter
// Return the data to be cached
}
}
In the above example, the @Cacheable annotation ensures that the getCachedData method is cached. Subsequent invocations with the same cache name and key will retrieve the cached result instead of executing the method again. Additionally, you can configure cache-specific settings such as eviction policies, time-to-live, and cache names.
