Connecting to rest endpoint

[Billiam leefer]

I am currently trying to create a simple Spring Boot application that I can send a request from my Postman application to a rest endpoint and the application will perform a basic operation on the data handed over and return the result in a Response.

Here is my RestService class with one endpoint that returns a message to say it was connected to:

package com.resources;
 
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
public class RestServiceTest {
 
    @RequestMapping(method = { RequestMethod.GET }, value = { "/testApplication" }, consumes = MediaType.ALL_VALUE, produces = MediaType.ALL_VALUE)
    public String getServerInfo() {
        System.out.println("I got hit");
        String message = "Hit the end point";
        return message;
    }
 
}

Here is my main class:

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

I hava an index.html containing a simple title and paragraphwhich shos when I run the app on server. I orginally had a web.xml but I found that my IDE, STS, doesn't need it and it actually got in the way so I deleted it.

When I connect to localhost:8080/testApplication via Postman or in my browser I am met with a 404 displaying "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists"



Here is my current pom.xml:

I have posted this to StackOverflow as well. One user has given me a configuration they say works for them but it does not work for me.

I am completely at the end of what I can do to fix this. What should be a simple task to introduce myself to Spring has turned into a nightmare. Any help will be appreciated. I will be more than happy to provide any additional information needed to solve this.

I've always considered Restful apps an advanced topic.  Might not be the best place for you to start.  Here is a tutorial for Restful apps using Spring Boot:  Spring Boot Restful apps

My code is right, I am sure of that, however my environment is wrong. I just got to figure out how it is wrong.
