Definition of spring boot framework
Spring boot framework is an open-source technology which was used to create microservices, this framework is used to create stand-alone and production applications. The framework is providing a very good platform for java developers to develop web-based and standalone applications, the framework is easy to understand and we can easily develop in application. Using a framework we can increase the productivity of our code and also reduce the time of development. All framework applications will need minimum configuration to implement the application.
What is spring boot framework?
- Spring boot is an open-source framework that a pivotal company maintained. Using the framework, it is possible to auto-configure the production-based application.
- We do not need to configure the application’s dependency using the framework manually.
- Spring boot framework in java provides a faster and easy way to set up and configure the web-based and standalone applications.
- It is nothing but the spring boot module, which provides the spring framework’s rapid application development (RAD) feature.
- To create the application using the framework, we can use the spring tool suite (STS), Eclipse IDE, or spring analyzer in java.
- The framework provides a perfect platform for java developers to develop standalone or web-based applications.
- The framework automatically configures our application’s dependency, so it will decrease the developer’s overhead using the software paradigm’s configuration.
- In the framework, automatic dependency is added using the annotation name EnableAutoConfiguration.
- The sprint boot framework is automatically configuring the database connection in memory. Suppose we are using the PostgreSQL database for reference in our database classpath. Still, we have not configured the database connection yet; the framework will automatically configure the database connection.
- Using framework transaction management is easy; we can quickly develop transaction management.
- Using framework, it’s easy to integrate our application into other frameworks like java or other languages.
- The cost and time management framework are beneficial compared to other frameworks because it will automatically resolve the dependency from the application code.
- Using the framework, we can implement easy and powerful batch processing of java applications.
- We can easily access the data from SQL and NoSQL databases using the framework.
- Framework is also providing robust security to our application. We can quickly provide complete security to our application by using a framework.
Create a project template using spring initializer and give the following name to the project metadata.
Group – com.example
Artifact name – spring-boot-framework
Name – spring-boot- framework
Description - Project of spring-boot- framework
Package name - com.example.spring-boot- framework
Packaging – Jar
Java – 11
Dependencies – spring web.
- After generating project extract files and open this project by using spring tool suite –
- After opening the project using the spring tool suite check the project and its files –
Spring boot framework examples
Below example and steps show framework are as follows.
- Add the dependency –
Code –
<dependency> -- Start of dependency tag.
<groupId>org.springframework.boot</groupId> -- Start and end of groupId tag.
<artifactId>spring-boot-starter-web</artifactId> -- Start and end of artifactId tag.
</dependency> -- End of dependency tag.
- Create web controller for application –
Code –
@RestController
public class springbootframework
{
@GetMapping ("/")
public String index() {
}
}
- Create application class –
Code –
@SpringBootApplication
public class framework {
public static void main /* main method */ (String[] args) {
SpringApplication.run (framework.class, args);
}
@Bean -- Bean annotation
public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
return args -> {
System.out.println ("Spring boot framework application");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort (beanNames);
for (String beanName : beanNames) {
System.out.println (beanName);
}
}; } }

Conclusion
Spring boot framework is used to create microservices applications in java. Using the framework, we are creating standalone and web-based applications. We do not need to configure the application’s dependency using the framework manually. The framework is essential for developing web-based applications.
