Spring boot jetty configuration example

Jetty Server Configuration for spring boot

Spring Boot web starters include default embedded containers as tomcat but you can use spring-boot-starter-jetty or spring-boot-starter-undertow instead.

When switching to a different HTTP server, you need to exclude the default dependencies in addition to including the one you need. Spring Boot Jetty configuration provides separate starters for HTTP servers to help make this process as easy as possible.

The following Maven example shows how to exclude Tomcat and include Jetty for Spring rest application

Jetty Starter configuration (pom.xml)

Add Jetty starter to your pom.xml and exclude embedded tomcat from web starter.

Launch as Spring boot (SpringBootWebApplication.java)

After launching this application, verify the console for jetty configuration init.

package com.candidjava.spring;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class SpringBootWebApplication {
 @RequestMapping("/")
 @ResponseBody
 String home() {
  return "Hello jetty server....!";
 }

 public static void main(String[] args) {
  SpringApplication.run(SpringBootWebApplication.class, args);
 }
