I am trying to make an example for the REST service from

https://spring.io/guides/gs/rest-service/

I have created all the 3 classes

I am sharing the code. I have seen the other question where there was a problem with the different packages but my classes are in the same package.

After i run the program i get the following result:

I see that the console says terminated so i do not know if this is the reason why i can not access the localhost:8080/greeting and i get that the site can't be reached

This project is built from Spring Tool 4 cause in Eclipse i get an error when i try to select from Projects the "Import Spring Getting Started Content", but this is a second problem.

The console gives the next:

. ____ _ __ _ _
 /\ / ___'_ __ _ _(_)_ __ __ _ 
( ( )___ | '_ | '_| | '_ / _` | 
 \/ ___)| |_)| | | | | || (_| | ) ) ) )
 ' |____| .__|_| |_|_| |___, | / / / /

I haven't changed the gradle file. There is nothing in the tutorial about Gradle file

After your proposal to add

compile("org.springframework.boot:spring-boot-starter-web") 

on gradle file when i run the application from IDE the program is terminated.

The same with maven from command.

Only gradle (gradle bootRun) from command line works and keeps running so the browser responses. SO what it is killing the app in these cases?

You might want to specify what method of RequestMethod it is:

e.g.

 @RequestMapping(value = "/greeting", method = RequestMethod.GET)

or

 @GetMapping("/greeting")

other than that it look sok to me.

You might want to look if you have the web starter in your build.gradle file.

Example in one file DemoGradleApplication:

package com.example.demogradle;

import lombok.AllArgsConstructor;
import lombok.Data;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.*;

import java.util.UUID;

@SpringBootApplication
public class DemoGradleApplication 

 public static void main(String args) 
 SpringApplication.run(DemoGradleApplication.class, args);
 


@RestController
class HelloWorldController 

 @RequestMapping(value = "/hello", method = RequestMethod.GET)
 public Message helloWorld() 
 return new Message(UUID.randomUUID()
 .toString(), "Hello, world!");
 

 @GetMapping("/hello/id:.*$")
 public Message hello(@PathVariable("id") String msg) 
 return new Message(UUID.randomUUID()
 .toString(), msg);
 


@Data
@AllArgsConstructor
class Message 

 private String id;
 private String message;

with gradle file:

buildscript 
 ext 
 springBootVersion = '2.1.0.RELEASE'
 
 repositories 
 mavenCentral()
 
 dependencies 
 classpath("org.springframework.boot:spring-boot-gradle-plugin:$springBootVersion")
 


apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories 
 mavenCentral()



dependencies 
 implementation('org.springframework.boot:spring-boot-starter-web')
 compileOnly('org.projectlombok:lombok')
 testImplementation('org.springframework.boot:spring-boot-starter-test')

Run with:

gradlew bootRun

Goto url http://localhost:8080/hello or http://localhost:8080/hello/you all rocking people in a browser

Try to replace your gradle

buildscript

apply plugin: 'java'

Also as spring boot document says you should locate you main application class in the root package above other class. Just a thought for you to work on.

This is the official spring boot doc:-
https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-structuring-your-code.html#using-boot-locating-the-main-class
