Spring Boot courses can help you learn how to create stand-alone, production-grade applications, manage dependencies, and implement RESTful APIs. You can build skills in configuring application properties, using Spring Data for database interactions, and securing applications with Spring Security. Many courses introduce tools like Maven or Gradle for project management and JUnit for testing, demonstrating how these tools streamline development processes and enhance application performance.
