Unable to autowire the MapStruct mapper

I was following this tutorial about the partial update. As instructed, I created mapper interface with proper annotations.

Here's the mapper

@Mapper(componentModel = "spring")public interface UserEntityMapper {  @Mapping(source = "password", target = "password")  @BeanMapping(nullValuePropertyMappingStrategy = NullValuePropertyMappingStrategy.IGNORE)  void updatePasswordFromDTO(PasswordResetRequest dto, @MappingTarget User entity);}

As per the tutorial, @Mapper(componentModel = "spring") generates mapper as a Spring bean that can be retrieved via @Autowired.

But when I tried to do same in my service layer class,

@Service@Transactionalpublic class AccountServiceImpl implements IAccountService {  ...  @Autowired  private UserEntityMapper userMapper;  ...}

I get this error, my application failed to start.

***************************APPLICATION FAILED TO START***************************Description:Field userMapper in com.application.services.AccountServiceImpl required a bean of type 'com.application.mappers.UserEntityMapper' that could not be found.The injection point has the following annotations:    - @org.springframework.beans.factory.annotation.Autowired(required=true)Action:Consider defining a bean of type 'com.application.mappers.UserEntityMapper' in your configuration.

And at last, here's pom.xml of my project.

Edit 1

Here's @SpringBootApplication file.

@SpringBootApplication@PropertySources(value = {  @PropertySource("classpath:mail.properties"),  @PropertySource("classpath:messages.properties"),  @PropertySource("classpath:security.properties")})public class Application {    public static void main(String[] args) {        SpringApplication.run(Application.class, args);    }}

Edit 2

Package structure of the project

Please help, Thank you :)
