There are some frequently used frameworks in the spring project of the new idea project.

I think Spring boot counts, because spring boot is easier to use than spring MVC and requires less configuration. It is highly recommended to learn Spring boot.

There are also spring data related projects, it depends on what storage you use. Generally speaking, they are spring-data-jpa, spring-data-redis, spring-data-elasticsearch, etc.

You can also learn about Spring security and Spring batch.

• SpringData, SpringSecurity, SpringBatch

• Forget it. I can't say it's related. Microservices is a concept and SpringBoot is a framework. SpringBoot can indeed be built as a microservice, but it does not mean that other frameworks cannot.

Spring-data is a must
