Examples of use
In short, Spring uses this two things to allow you to build business applications with different levels of complexity. For example:
- microservices as backend
- standard backend applications
- cloud based applications
- REST APIs
Concluding, spring makes programming Java apps easier, quicker and safer. Spring increases speed and productivity of creating a software which has made it the most famous Java framework.
