Not able to read consul key value properties into spring boot application - spring-boot

Question

I am very new to the consul. Started with POC, able to establish communication between two services using the consul, but unable to read key/value pairs from consul into spring boot application.
Have gone through all the solutions available on the internet to understand what I am doing wrong, but nothing helped me.
Please take a look at the code below and suggest to me if I am doing any mistakes
Main class:
#SpringBootApplication
#EnableAutoConfiguration
#RestController
#EnableConfigurationProperties(value = {PropertySourceBootstrapProperties.class})
#EnableDiscoveryClient
public class KeyvalueApplication {
#Value("${greeting}")
private String greeting;
#GetMapping("/keys")
public String getName() {
return "Config data "+ greeting;
}
public static void main(String[] args) {
SpringApplication.run(KeyvalueApplication.class, args);
}
}

I am using consul version 1.9.2
I used the below command to start the consul agent:
consul agent -server -bootstrap-expect=1 -data-dir=consul-data -ui -bind= -client 0.0.0.0
I configured key-value pair in consul UI as config/keyvalue/greeting:
When I run my spring boot application I am getting the error:
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'greeting' in value "${greeting}"
