What is the difference between Spring Tool Suite 3 and 4?

Question

I want to study Spring. In the case of STS (Spring Tool Suite) 3, there is "Spring legacy Project". 4 has a "Spring Starter Project", is it the same?

When I asked the Internet, people say "just use version 3".

1. What is the difference between version 3 and version 4?
2. Is "Spring Starter Project" and "Spring Legacy Project" the same thing?

Answer 1

1.What is the difference between version 3 and version 4?

Version 4.0 is the latest major release of the Spring Framework and the first to fully support Java 8 and few new features.[more]

2. Is "Spring Starter Project" and "Spring Legacy Project" the same thing?

Technically both are same spring project's. But they have some difference in configuration and build areas.

Spring Starter Project- Helps to create the spring boot project.(Spring Boot is basically an extension of the Spring framework which eliminated the boilerplate configurations required for setting up a Spring application.)

Spring Legacy Project - Helps to create the spring maven project. In which all the required configuration like servlet context,web,.. need to be configured manually either by using xml file or java classes.

Take a look at this page to know more about the difference between spring vs spring boot

If you are going to start learning spring from beginning, my suggestion is use Spring Starter Project because in Spring boot project setup is so simple, you can start coding with zero manual configuration.
