Increment doesnt work

Hi Guys,

Currently im learning devsecops and on the section “Demo-Kubernetes Deployment”. When i deploy to kubernetes the deployment were all good, but when i tested the numericapplication with “/increment/77” the web page didnt show 78. Here’s my numericcontroller.java code:
package com.devsecops;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;

@RestController
public class NumericController {

private final Logger logger = LoggerFactory.getLogger(getClass());
private static final String baseURL = "http://node-service:5000/plusone";

RestTemplate restTemplate = new RestTemplate();

@RestController
public class compare {

	@GetMapping("/")
	public String welcome() {
		return "Kubernetes DevSecOps";
	}

	@GetMapping("/compare/{value}")
	public String compareToFifty(@PathVariable int value) {
		String message = "Could not determine comparison";
		if (value > 50) {
			message = "Greater than 50";
		} else {
			message = "Smaller than or equal to 50";
		}
		return message;
	}

	@GetMapping("/increment/{value}")
	public int increment(@PathVariable int value) {
		ResponseEntity<String> responseEntity = restTemplate.getForEntity(baseURL + '/' + value, String.class);
		String response = responseEntity.getBody();
		logger.info("Value Received in Request - " + value);
		logger.info("Node Service Response - " + response);
		return Integer.parseInt(response);
	}
}

}

Thanks.
