Help with Resource Not Found Complete 4040 NOT_FOUND

[Jim Ritchhart]

I'm new to Java / Spring / Rest / etc/   I have gone through the Java Full Stack with Spring Boot and Angular by in28Minutes.  

I'm having an issue that I'v been frustrated with all day.   Getting Resource Not Found Complete 4040 NOT_FOUND error when trying a very simple rest call.  
I have researched all over the web trying to help myself.   Need to reach out for some help.     THANKS IN ADVANCE!!!

I make the URL call as:  http://localhost:9090/test   in Postman and get the Resource Not Found Error.

Application class is this:

package com.replicatedtablereference;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication()
@ComponentScan(basePackages = {"com.replicatedtablereference.*"})
@EntityScan(basePackages = {"com.replicatedtablereference.*"})
@EnableJpaRepositories(basePackages = {"com.replicatedtablereference.*"})
public class ReplicatedtablereferenceApplication {

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

}

Rest endpoint looks like this:

package com.replicatedtablereference.resources;

import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;


@CrossOrigin
@RestController
public class Example {

    @RequestMapping(path="/test")
    public  ResponseEntity<String> example() {
    	    	return new ResponseEntity<String>("HI", HttpStatus.OK);
    	    	
 }

}

Issue seemed to be with JWT getting in the way.    I had started pairing down as much stuff as possible and nothing was working.   This morning I removed all JWT code and disabled security and that worked.   Now I started putting things back.
