I have EmailService and EmailCofig Class as below :

package com.javavogue.demo.service;

import org.springframework.boot.context.properties.ConfigurationProperties;

public class EmailConfig {
     private String   username;
     private String  email;
	
     public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	
	@Override
	public String toString() {
		return "EmailConfig [username=" + username + ", email=" + email + "]";
	}
    
}

 

package com.javavogue.demo.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

@Service
public class EmailService {

	 @Autowired
	 private EmailConfig emailConfig;
	 
	public void sendEmail(){
		
		System.out.println("EmailCOnfig ==="+ emailConfig.toString());
		
	}
	
}

Solution :

Use @Service  Or @Component anotation In EmailConfig Class Above .

package com.javavogue.demo.service;

import org.springframework.boot.context.properties.ConfigurationProperties;
@Service
public class EmailConfig {
     private String   username;
     private String  email;
	
     public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	
	@Override
	public String toString() {
		return "EmailConfig [username=" + username + ", email=" + email + "]";
	}
    
}
