Spring boot rest with PUT POST HEAD OPTIONS

Goal

In my last article I built a simple hello world Rest service with spring boot, now i want to introduce more examples trying to light up various aspects of restful service.

Used technologies

JDK 1.8
Maven 3.2

pom.xml

  <dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
	</dependencies>
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

Model: Tutorial

package com.wstutorial.rest;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Tutorial {
	private long id ;
	private String name;
	private String author;

	public Tutorial() {
	}

	public Tutorial(long id , String name, String author) {
		this.id = id;
		this.name = name;
		this.author = author;
	}
	..
}

Resource: TutorialResource

Set the port

server.port=10080

Rest Starter

package com.wstutorial.rest;

import com.sun.jersey.api.container.httpserver.HttpServerFactory;
import com.sun.net.httpserver.HttpServer;

public class StartRestServer {
	public static void main(String[] args) {
		HttpServer server;
		try {
			server = HttpServerFactory.create( "http://localhost:10080/api" );
			server.start();
		}catch (Exception e) {
			System.out.println("Errormessage : " + e.getMessage());
		}

	}
}

Call the urls

To obtain all tutorials: http://localhost:10080/api/tutorials
Just only one specific tutorial: http://localhost:10080/api/tutorials/2

Using curl

curl -i http://localhost:10080/api/tutorials
curl -i http://localhost:10080/api/tutorials/1
curl -H "Content-Type: application/json" -X POST -d '{"author":"Adam snake","id":"1","name":"Python Basics"}' http://localhost:10080/api/tutorials
curl -H "Content-Type: application/json" -X PUT -d '{"author":"Adam changed","id":"1","name":"Python Basics"}' http://localhost:10080/api/tutorials
curl -X DELETE http://localhost:10080/api/tutorials/1
curl -X HEAD http://localhost:10080/api/tutorials/1 (doesn't work properly)
curl -X OPTIONS http://localhost:10080/api

TestClient

RestTemplate put and delete methods are void
If you want to check the response, you can use the exchange method

    @Test
	public void testDeleteWithExchange() {
		ResponseEntity
             response = template.exchange(endpoint + "/2", HttpMethod.DELETE, null,ResponseEntity.class);
		assertNotNull(response);
		assertTrue(response.getStatusCode() == HttpStatus.OK);
	}
