YQ01‐Java EE vs Spring Boot

Java EE (Jakarta EE)

What it is:

1. A standard specification for enterprise Java

2. Defines APIs for:

   • Servlet
   • JSP
   • EJB
   • JPA

3. Needs a server like:

   • Apache Tomcat
   • WildFly

Advantages:

1. Strong standard & structure
2. Good for learning fundamentals (MVC, layering)
3. Used in traditional enterprise systems

❌ Disadvantages:

1. More boilerplate code
2. Manual configuration (XML, deployment)
3. Slower development
4. JSP is outdated in modern apps

Spring Boot

What it is:

1. A modern Java framework
2. Built on top of Spring
3. Designed for fast development
4. Comes with:
   • Embedded server (Tomcat built-in)

Advantages:

1. Very fast development
2. Minimal configuration (auto-config)
3. Built-in REST API support
4. Easy deployment (just run .jar)
5. Works well with cloud (Railway, Render, etc.)

❌ Disadvantages:

1. Less focus on fundamentals (students may skip basics)
2. “Magic” auto-config can confuse beginners
