Spring Boot is a lightweight Java-based framework used to create a microservice. It is also useful for configuring Spring-based applications. Moreover, Spring Boot Starter is a starter for building web applications using Spring MVC. The Spring Boot Starters are built to address the issues of dependency management. It is a critical aspect of any project.

Spring Boot is an open-source free to use Java framework that supports in developing Java applications easily. Spring Boot provides many starters that allow the user to add jars in the classpath. Moreover, by using the built-in Spring Boot Starters, the users can improve the development process easily and quickly.

Spring Boot Starter Web usage

Spring Boot starter is a module under Spring Boot that helps Java developers to develop standalone spring applications. These are built to just run. It doesn’t require heavy configurations. Moreover, the Starters help to bootstrap the user’s application which needs a correct starter in the application. Spring enables its users to run applications individually. Furthermore, the Spring Boot Web is a specific module designed for writing various rest endpoints.

The Spring Boot web depends on the following starter packs. Such as;

• boot: Spring Boot starter
• Springframework: spring-webmvc
• boot: spring boot-starter-tomcat
• Springframework: spring-web

Furthermore, we will discuss the various aspects of the Spring Boot web. These starters serve different purposes for web applications.

Spring Boot Starter POM

For any Spring project, POM (Project Object Module) is the key essential which is a part of Maven. The Spring Boot POMs help to add spring boot web dependencies well. Besides, the web starter also helps to build web applications. It helps the user to not remember the dependencies. Further, it also helps in structuring the version control within the XML. This makes the application free of any version errors. Moreover, these are the best features of Spring Boot that help to simplify the development of Spring applications.

Here, we use the following XML structure to import the dependencies.

org.springframework.boot
spring-boot-starter-web

The Spring Boot Web is a starter pack that present in Spring Boot. The Spring Boot Web has two important features. Spring starter web is compatible with web development. Moreover, it includes various essential dependencies. It also has a feature of auto-configuration.

To get practical insights into Spring Boot web one can opt for Spring Boot Course from online sources.

The Spring web uses various tools like Spring MVC, REST, Tomcat, etc as default servers. It helps the developers to reduce the building of dependency.  These features help to build rich applications easily and rapidly. They help to work more productively. Furthermore, there are some other features also. Such as; type-safe configuration, logging, powerful abstraction, lightweight features, etc. Moreover, many companies prefer to use Spring Boot for developing Java.

The Spring Starter web auto-configures dispatcher servlet, error page, web jars, etc. Moreover, it holds an embedded servlet container (Tomcat-default).

Spring Boot Starter examples

The following examples explain the spring boot starters as an overview. These examples give an idea of the spring starter. Moreover, they explain the use of Spring boot starter having dependencies.

Spring Boot Web Dependency

This starter web dependency is useful to write Rest endpoints. The syntax of this is;

   org.springframework.boot
   spring-boot-starter-web

Spring Boot Security dependency

This Spring Starter is useful for Spring security. The example for it is as follows.

   org.springframework.boot
   spring-boot-starter-security

Spring Boot Test dependency

This Spring starter is useful for test case writings. The codes are written very small and easy to use. The code for this is as follows.

   org.springframework.boot
   spring-boot-starter-test

Data JPA starter:

The Spring starters generally come with JPA starters that contain standards for the persistence. Moreover, these JPA dependencies need no manual configuration. They need to just add to the application. The following code will elaborate on it well.

    org.springframework.boot
    spring-boot-starter-data-jpa

    com.h2database
    h2

Moreover, the Spring Boot Web framework has many other uses and web services. These are as follows. :

a) Spring boot-starter web services: It includes the usage of Spring web services.

b) Spring boot-starter thyme leaf: This starter is useful to build MVC web applications.

c) Spring boot starter mail: This framework is useful for Java mail and Spring frameworks emailing.

   org.springframework.boot
   spring-boot-starter-mail

d) Spring-boot-starter web: The Starter helps to build web applications. It also includes RESTful applications.

e) Spring-boot-starter gem fire: This Starter is useful for Spring data gem fire and data store.

f) Spring-boot-starter integration: This framework is helpful for Spring Integration.

Furthermore, there are many other Spring boot starters. Such as; production starters, technical starters, third party starters, etc. These starters help web applications in many ways. Spring boot is an integration of various applications developed in the Spring ecosystem. These are JDBC, Spring ORM, etc.

Custom Spring Boot Starter

To create a custom Spring Starter the user needs to write some components. Such as;

• An Auto configuration class for the library for custom configuration. It also includes a property class.
• A Starter POM also needs to bring the dependencies of the library along with the auto-configure project.

The Auto configure module consists of Greeter properties and Greeter Autoconfiguration. It is written as a greeter-spring-boot-auto configure. Besides, these classes enable to set up custom property through application property file. On the starting of an application, the Greeter Auto Configuration file will run. It is done in the case of Greeter present in the classpath. Moreover, if the run is successful, then it will populate the Spring application.

Creating the POM.XML file also includes the same properties as the auto-configure file. The whole process will repeat here also. Moreover, the Spring Boot automatically configures everything.

Advantages of Spring Boot Starter:

The starter web applications of spring boot can be built very easily and quickly. Besides, it offers different templates for Hibernate, JDBC, etc to reduce the code writing length. The applications build using Spring are simple to use and fit in every environment. It prefers writing short scripts. And also avoids XML configurations for improvements.  Moreover, it saves a lot of time for development and helps to increase productivity.

The Starter projects of Spring Boot help to increase the productivity of a developer. They provide various defaults and configurations. Besides, it reduces the developer’s efforts in writing long codes. Moreover, it helps to select the modules among its many modules to use and get quick results. The spring boot has good configuration controls within it. Furthermore, all these help the applications with production-ready platforms.  The Spring boot architecture is a basic spring boot application. Moreover, the configuration of this application is generally developed by using various annotations. These annotations are the form of metadata that help to provide data of the program. Besides, the Spring Boot consists of embedded HTTP servers using which developers can test their web applications easily. The results of the test also come very quickly.

Conclusion

Thus, the above writings explain Spring Boot Starter and its various features. It gives an overview of the Spring Boot and its different aspects and uses. Moreover, there are many companies currently prefer this feature. It helps to use for application development in different environments. It helps in the quick and faster development of Java applications with this architecture. Furthermore, there are many uses of Spring Boot and its various features that help to build applications.

To get practical knowledge of Spring Boot and its different uses one can opt for Spring Boot Online Training from various online sources. This learning may help to fill the skill gap and enhance chances to get a successful career.
