What are Spring Boot Starters and why are they useful? स्प्रिंग बूट स्टार्टर्स क्या हैं और ये क्यों उपयोगी हैं?

Spring Boot Starters are curated sets of dependency descriptors that bundle all the libraries needed for a specific feature, such as spring-boot-starter-web for building REST APIs or spring-boot-starter-data-jpa for JPA-based persistence.

Instead of manually resolving compatible versions of many related libraries, a starter pulls in a tested, compatible set with one dependency, reducing version-conflict issues and speeding up project setup. Starters follow the naming convention spring-boot-starter-*, and third-party libraries often publish their own starters following the same pattern.

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
</dependency>
