Using spring-boot-starter-jetty in Spring Boot

As a senior Spring Framework developer, you might already be familiar with the default embedded Tomcat server in Spring Boot applications. However, there are scenarios where you might prefer using Jetty instead of Tomcat. Jetty is known for its lightweight nature and small footprint, making it ideal for resource-constrained environments or microservices architectures. In this blog post, we’ll explore how to replace Tomcat with Jetty in a Spring Boot application and provide some practical examples.

Why Choose Jetty?

Jetty offers several advantages:

  • Lightweight and Fast: Jetty has a smaller memory footprint and can start up faster than Tomcat.
  • Scalability: Jetty is designed to handle large numbers of connections efficiently.
  • Flexibility: Jetty can be easily embedded in applications, making it a good choice for microservices.

Setting Up Jetty in Spring Boot

To use Jetty in your Spring Boot application, follow these steps:

  1. Exclude Tomcat and Include Jetty: Modify your pom.xml (for Maven) or build.gradle (for Gradle) to exclude the default Tomcat dependency and include the Jetty dependency.

    Maven:

    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jetty</artifactId>
</dependency>

    Gradle:

    configurations {
    compile.exclude module: "spring-boot-starter-tomcat"
}

dependencies {
    implementation "org.springframework.boot:spring-boot-starter-web"
    implementation "org.springframework.boot:spring-boot-starter-jetty"
}

  2. Configure Jetty Properties: You can customize Jetty settings in your application.properties or application.yml file. Here are some common configurations:

    application.properties:

    server.port=8080
server.jetty.acceptors=2
server.jetty.selectors=4
server.jetty.max-http-post-size=0

    application.yml:

    server:
  port: 8080
  jetty:
    acceptors: 2
    selectors: 4
    max-http-post-size: 0

  3. Run Your Application: With these changes, your Spring Boot application will now use Jetty as the embedded server. You can run your application as usual, and it will start with Jetty.

Example: Creating a Simple REST API

Let’s create a simple REST API to demonstrate the use of Jetty in a Spring Boot application.

  1. Create a Spring Boot Application: Use Spring Initializr to create a new Spring Boot project with the necessary dependencies (spring-boot-starter-web and spring-boot-starter-jetty).

  2. Define a REST Controller: Create a simple REST controller to handle HTTP requests.

    import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String sayHello() {
        return "Hello, Jetty!";
    }
}

  3. Run the Application: Run your Spring Boot application, and navigate to http://localhost:8080/hello. You should see the message “Hello, Jetty!”.

Conclusion

Switching from Tomcat to Jetty in a Spring Boot application is straightforward and can offer performance benefits in certain scenarios. By following the steps outlined above, you can easily configure your application to use Jetty and take advantage of its lightweight and scalable nature.

Happy coding! 🚀

Understanding spring-boot-starter-tomcat in Spring Boot

Spring Boot simplifies the process of developing stand-alone, production-grade Spring-based applications. One of the key features that make this possible is the use of starters. In this blog post, we’ll dive into the spring-boot-starter-tomcat starter, which provides the necessary dependencies to run an embedded Tomcat server within a Spring Boot application. What is spring-boot-starter-tomcat ? The spring-boot-starter-tomcat is a starter for using Tomcat as the embedded servlet container. By including this starter, you can run your Spring Boot application with an embedded Tomcat server, eliminating the need to deploy your application to an external server. Adding spring-boot-starter-tomcat to Your Project To use the spring-boot-starter-tomcat , you need to include it in your pom.xml if you’re using Maven: < dependency > < groupId > org.springframework.boot </ groupId > < artifactId > spring-boot-starter-tomcat </ artifactId > </ d...
