Java: Jetty with String Boot

Final Project structure:




Step 1: From STS create a new project. (New > Spring Starter Project).





Step 2: Update pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

### Please note that the support for release > 1.5.5.RELEASE is broken. This version worked for me
<version>1.5.4.RELEASE</version>

</dependency>

###Add dependency to Jetty
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jetty</artifactId>
</dependency>

</dependencies>

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>


</project>

Step 3: Edit your start-up class

package com.blogspot.georgelache;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoJettyApplication {

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

Step 4 (optional): Add your context listener

package com.blogspot.georgelache;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import org.springframework.stereotype.Component;

@Component
public class AppServletContextListener implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent sce) {
System.out.println("*** contextInitialized");
}

@Override
public void contextDestroyed(ServletContextEvent sce) {
System.out.println("*** contextDestroyed");
}
}

Step 5: Create a test rest controller

package com.blogspot.georgelache.web;

import org.springframework.web.bind.annotation.RequestMapping;

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

@RestController

public class HelloJetty {

@RequestMapping("/hello")

public String getHello() {

return "Hello";

}

}

Step 6: Update application.property in order to customize the server 

#Startup port

server.port=8866

# The Context Path 

server.contextPath=/jetty

#Jetty Settings

server.compression.enabled: true

server.compression.min-response-size: 1

server.jetty.acceptors=2

Step 7: Run your application (as Java Application)
