ContextRefreshedEvent is not being catched - spring-boot

Question

I am setting up a spring boot application with postgres database
The postgres server is up and does not have much to do with the issue.
Following are my classes:
package com.example.demo.service.config;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.event.ContextStartedEvent;
#SpringBootApplication
public class ServiceConfiguration {
public static void main(String[] args) {
SpringApplication.run(ServiceConfiguration.class, args);
}
}
package com.example.demo.service.config;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.transaction.annotation.EnableTransactionManagement;
#Configuration
#EnableAutoConfiguration
#EntityScan(basePackages = {"com.example.demo.persistence"})
#EnableJpaRepositories(basePackages = {"com.example.demo.repositories"})
#EnableTransactionManagement
public class RepositoryConfiguration {
}
package com.example.demo.repositories;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Component;
import com.example.demo.persistence.Product;
#Component
public interface ProductRepository extends CrudRepository<Product, Integer>{
}
package com.example.demo.persistence;
import javax.persistence.*;
import java.math.BigDecimal;
#Entity
public class Product {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#SequenceGenerator(name="product_id_sequence", sequenceName="product_id_sequence", allocationSize=1)
#Column(name="ID")
private Integer id;
#Version
private Integer version;
private String productId;
private String description;
private String imageUrl;
private BigDecimal price;
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public Integer getVersion() {
return version;
}
public void setVersion(Integer version) {
this.version = version;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getProductId() {
return productId;
}
public void setProductId(String productId) {
this.productId = productId;
}
public String getImageUrl() {
return imageUrl;
}
public void setImageUrl(String imageUrl) {
this.imageUrl = imageUrl;
}
public BigDecimal getPrice() {
return price;
}
public void setPrice(BigDecimal price) {
this.price = price;
}
}
package com.example.demo.bootstrap;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;
import org.springframework.stereotype.Component;
import com.example.demo.persistence.Product;
import com.example.demo.repositories.ProductRepository;
import java.math.BigDecimal;
#Component
public class ProductLoader implements ApplicationListener<ContextRefreshedEvent> {
private ProductRepository productRepository;
private Logger log = Logger.getLogger(ProductLoader.class);
#Autowired
public void setProductRepository(ProductRepository productRepository) {
this.productRepository = productRepository;
}
#Override
public void onApplicationEvent(ContextRefreshedEvent event) {
System.err.println("Flow never comes here !!");
Product shirt = new Product();
shirt.setDescription("Spring Framework Guru Shirt");
shirt.setPrice(new BigDecimal("18.95"));
shirt.setImageUrl("https://springframework.guru/wp-content/uploads/2015/04/spring_framework_guru_shirt-rf412049699c14ba5b68bb1c09182bfa2_8nax2_512.jpg");
shirt.setProductId("235268845711068308");
productRepository.save(shirt);
log.info("Saved Shirt - id: " + shirt.getId());
Product mug = new Product();
mug.setDescription("Spring Framework Guru Mug");
mug.setImageUrl("https://springframework.guru/wp-content/uploads/2015/04/spring_framework_guru_coffee_mug-r11e7694903c348e1a667dfd2f1474d95_x7j54_8byvr_512.jpg");
mug.setProductId("168639393495335947");
productRepository.save(mug);
log.info("Saved Mug - id:" + mug.getId());
}
}
The ProductLoader class is a component and implements ApplicationListener, still the flow never comes in onApplicationEvent(ContextRefreshedEvent event) method.
Can anybody help?

Got the issue resolved.
Added following annotations to the ServiceConfiguration class
#SpringBootApplication(scanBasePackages = {"com.example.demo.bootstrap","com.example.demo.persistence"})
#EnableJpaRepositories(basePackageClasses = {ProductRepository.class})
#EntityScan(basePackageClasses=Product.class)
public class ServiceConfiguration {
public static void main(String[] args) {
SpringApplication.run(ServiceConfiguration.class, args);
}
}
