Почему возникает ошибка «parameter 1 of constructor in required a bean of type that could not be found.»?

Question

[Сергей Беловенцев]

вот сервис
CompanyService

package ru.sergalas.perpay.entities.companies.service;

import org.springframework.stereotype.Service;
import ru.sergalas.perpay.entities.companies.mappers.CompanyMapper;
import ru.sergalas.perpay.entities.companies.repository.CompaniesRepository;

@Service
public class CompaniesService {

    private final CompaniesRepository companiesRepository;

    private final CompanyMapper companyMapper;

    public CompaniesService(CompaniesRepository companiesRepository, CompanyMapper mapper)
    {
        this.companiesRepository = companiesRepository;
        this.companyMapper = mapper;
    }
}

вот ComapanyMapper

package ru.sergalas.perpay.entities.companies.mappers;

import org.mapstruct.Mapper;
import org.mapstruct.Mapping;
import ru.sergalas.perpay.entities.companies.dto.CompanyReadDTO;
import ru.sergalas.perpay.entities.companies.dto.CompanyWriteDTO;
import ru.sergalas.perpay.entities.companies.entity.Companies;
import java.util.UUID;

@Mapper(imports = UUID.class)
public interface CompanyMapper {

    CompanyReadDTO toDTO(Companies companies);

    @Mapping(target="id", source="id", defaultExpression = "java( UUID.randomUUID())")
    Companies toEntity(CompanyWriteDTO dto);
}

вот gradle

plugins {
	id 'java'
	id 'org.springframework.boot' version '2.7.10'
	id 'io.spring.dependency-management' version '1.0.15.RELEASE'
}
apply from: 'version.gradle'

group = 'ru.sergalas'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

configurations {
	compileOnly {
		extendsFrom annotationProcessor
	}
}

repositories {
	mavenCentral()
}

dependencies {
	implementation 'org.liquibase:liquibase-core'
	implementation "com.google.code.gson:gson:${versions.gson}"
	implementation "io.jsonwebtoken:jjwt-api:${versions.jjwt}"
	implementation "org.json:json:${versions.json}"
	implementation "org.projectlombok:lombok-mapstruct-binding:${versions.lombokmapstruct}"
	compileOnly "org.mapstruct:mapstruct:${versions.mapstruct}"

	compileOnly 'org.projectlombok:lombok'

	runtimeOnly 'org.postgresql:postgresql'
	runtimeOnly "io.jsonwebtoken:jjwt-impl:${versions.jjwtimpl}"
	runtimeOnly("io.jsonwebtoken:jjwt-orgjson:${versions.jjwtimpl}") {
		exclude group: 'org.json', module: 'json'
	}

	annotationProcessor 'org.projectlombok:lombok'
	annotationProcessor "org.mapstruct:mapstruct-processor:${versions.mapstructProcessor}"
}

tasks.named('test') {
	useJUnitPlatform()
}

при сборке проекта получаю ошибку

Parameter 1 of constructor in ru.sergalas.perpay.entities.companies.service.CompaniesService required a bean of type 'ru.sergalas.perpay.entities.companies.mappers.CompanyMapper' that could not be found.

Answer 1

[Сергей Беловенцев]

Надо было создать конфигурационный фаил где прописать эти маперы в бины )))

Answer 2

[Станислав Агарков]

Поставьте @Component на класс маппера.
