It has been already made clear, what spring boot is? However, though we have already mentioned about what spring boot is, a question that remains is, what is micro service?

Micro Service can be defined as an architecture that enables developers to develop, organize and serves individually and independently. Each of the services which are running has its own specific function and process, by thus the end result being, outputting a frivolous model that supports business applications.

  • Easy Deposition
  • Saving time as it reduces the production time
  • Compatible with Containers
  • Minimum configuration
  • Simple scalability

Micro Service offers any developer the aforesaid advantages.

Now that we have understood Micro Service, let us dig deep to know more about Spring Boot. The main purpose of Spring Boot is to ease the process of creating production-grade spring-powered applications and services, given that minimum fuss is created. Putting Spring Boot in simple words, we can say that it is a framework developed by the ‘Spring Team’ that aids in easing the bootstrapping and creation of any novel Spring Applications. It usually functions by providing defaults for the codes and annotation configuration that will help in quickly starting any new Spring projects in real-time. Furthermore, it also follows the ‘Opinionated Defaults Configuration’ strategy in order to avoid a lot of boilerplate code and other configurations that were meant to improve the Unit Test, Development, and Integration Test procedures.

Features of Spring Boot

The Spring Boot program has been designed to achieve the below-mentioned goals.

  • Avoiding complex XML configurations,
  • To easily develop ready to use Spring applications.
  • It visions to reduce the time taken to develop and run the developed applications.
  • It foresees to offer an easier way to start the applications. Though the above-mentioned indicators are the distinguishing features of spring Boot, the benefits and if it does not end here.
  • One can choose Spring Boot because of the flexibility in configuring XML configurations, Java Beans, and Database Transaction.
  • It gives a strong batch processing and even manages REST endpoints of reduced time. Being automated gives Spring boot an upper hand as no manual configurations are needed.
  • It is able to offer automated spring applications.
  • It can ease the dependency and comes with Embedded Servlet Container.

Advantages of Spring Boot

Below-mentioned are some of the advantages of Spring Boot:

  • The primary advantage is spring boot offers an effortless way to create spring-based applications using JAVA or Groovy.
  • The greatest advantage is the reduced time. Spring Boot minimizes the time spent in developing and increasing productivity.
  • Also, it helps in reducing all the manual work of writing annotations, boilerplate codes and XML configurations.
  • It has made the integration of Spring Boot Application with its Spring Ecosystem which includes Spring Security, Spring Data, Spring JDBC and Spring ORM easy.
  • By following the ‘Opinionated Defaults Configuration’, it also reduces the efforts of developers.
  • Developers have easy access to Embedded HTTP servers such as Jetty, Tomcat and also easily test the web applications effortlessly.
  • Spring Boot gives easy access to Command Line Interface which has made the developing and testing of Spring Boot applications developed with Java or Groovy agile.
  • Alongside, it also provides a lot of plugins which aids in effortless development and testing of Spring Boot application build with the help of tools like Gradle and Maven.
  • Lastly, it provides a plugin that has made working with embedded and in-memory database very smoothly and readily.

Disadvantages of Spring Boot

Almost perfect, yet Spring Boot has one limitation. The only problem lies in the time consumed in the process of converting the legacy or already existing Spring Framework projects to Spring Boot Applications.
