A Quick Comparison Between Spring Boot and Quarkus

Introduction

Microservices have become more popular recently, so people have made many small tools to help create them. Spring Boot and Quarkus are two very popular tools in this field. A lot of developers have been using Spring Boot for a long time, but now more and more are starting to use Quarkus because it works better and doesn't need as much computer memory. In this blog, we will look at two frameworks and explain how they are different using examples.

Spring Boot

Spring Boot is a Java tool that helps create small services quickly and easily. This is made using the Spring Framework, which is widely used for making big business software. Spring Boot makes it easy for developers to create software by offering ready-made pieces that they can use to build their apps fast. This has different tools like self-setup, built-in servers, and measurement tools.

Making a way for software programs to communicate with each other using Spring Boot.

To show how simple it is to make a REST API using Spring Boot, let's look at this example. Let's say we need to make a tool that shows a list of employeesusing a REST API. We can use this code to make our controller work.

@RestController
public class EmployeeController {

@GetMapping("/employees")
public List<Employee> getEmployees() {
List<Employee> employees = new ArrayList<>();
employees.add(new Employee(1, "Dhiraj Chauhan"));
employees.add(new Employee(2, "Ansul Rajput"));
return employees;
}
}

Quarkus

Quarkus is a software tool that helps developers create applications quickly and efficiently. It's designed to work with modern technologies and can be used to build a variety of different applications.
Quarkus is a new way to make software using Java that is perfect for making programs that work well on the internet. This is a simple and fast way to develop small computer programs called microservices. It uses special tools called Vert.x and Hibernate ORM. Quarkus has unique features such as compiling in advance, coding live, and supporting different ways of deployment. It is a great choice to use for making new apps that work well and use less space.

Example: Creating a REST API with Quarkus

This example will show how simple it is to make a REST API using Quarkus. Imagine we want to make a tool that gives us a list of employess. We can use this code to create our controller.

@Path("/employees")
public class EmployeeResource {

@GET
@Produces(MediaType.APPLICATION_JSON)
public List<Employee> getEmployees() {
List<Employee> employees = new ArrayList<>();
employees.add(new Employee(1, "Dhiraj Chauhan"));
employees.add(new Employee(2, "Ansul Rajput"));
return employees;
}
}

Comparison andContrasts

1. Architecture & Design

Spring Boot is a program that is made from Spring Framework. Spring Framework has different parts that you can use to make business programs. Quarkus is a tool for making computer programs that work well in the cloud. It is made to be quick and efficient.

2. Performance &Execution

Quarkus is faster and uses less memory than Spring Boot. This is made possible by doing things to make the computer program faster and more efficient, like pre-compiling it, making it take up less space, and using resources better.

3. Developer Experience

Spring Boot makes it easy for developers to write code by automatically setting up the necessary configurations and being user-friendly. With Quarkus, developers can now see the changes they make to their code happening in real time through its live coding feature.

4. Supported Technologies

Spring Boot has existed for a long time and has many libraries and plugins available. Quarkus is quite new, so it is still trying to improve in this area. However, it can help a lot with different ways to put your program into action, like using Kubernetes, serverless, and others.

Conclusion

In short, Spring Boot and Quarkus are great tools to make Microservices.
