Why has Spring Boot become so popular compared to Java EE?

Spring Boot has become popular compared to Java EE (now Jakarta EE) due to several key advantages:

• Auto-configuration: Spring Boot significantly simplifies application setup by automatically configuring components based on dependencies and settings, reducing development time.

• Embedded application server: Unlike traditional Java EE, where WAR files need to be deployed on an external server, Spring Boot allows running the application as a standalone JAR with an embedded server (e.g., Tomcat or Jetty).

• Minimal XML configurations: Spring Boot uses annotations and properties instead of bulky XML configurations, making the code cleaner and more understandable.

• Large community and ecosystem: Spring Boot is supported by a strong community and integrates with many libraries and tools.

• Flexibility and modularity: You can easily add necessary dependencies and components without overloading the project with unnecessary features.

In the end, Spring Boot enables faster creation of production-ready applications with less effort and a more convenient architecture compared to traditional Java EE.
