JdbcTemlate - No qualifying bean of type available

Question

I want to configure on xml JdbcTemolate.

it looks like this

<context:property-placeholder location="classpath:db/postgres.properties"/>

<bean id="dataSource"
      class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="${database.driverClassName}"/>
    <property name="url" value="${database.url}"/>
    <property name="username" value="${database.username}"/>
    <property name="password" value="${database.password}"/>
</bean>

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <constructor-arg ref="dataSource"/>
</bean>


<bean id="namedJdbcTemplate" class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate">
    <constructor-arg ref="dataSource"/>
</bean>

but I get such an error

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'jdbcMealServiceImpl': Unsatisfied dependency expressed through field 'jdbcMealRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'ru.demo.exercise.repository.jdbc.JdbcMealRepository' available: expected at least 1 bean which qualifies as autowire candidate.

This is my JdbcService:

@Service
public class JdbcMealServiceImpl implements MealService {
    @Autowired
    JdbcMealRepository jdbcMealRepository;

    @Override
    public Meal save(Meal meal) {
        return jdbcMealRepository.save(meal);
    }

    @Override
    public Meal get(int id) {
        return jdbcMealRepository.get(id);
    }

    @Override
    public List<Meal> getAll() {
        return jdbcMealRepository.getAll();
    }

    @Override
    public void delete(int id) {
        jdbcMealRepository.delete(id);
    }

    @Override
    public void update(Meal meal) {
        jdbcMealRepository.update(meal);
    }
}

JdbcRepository:

@Repository
public abstract class JdbcMealRepository implements MealRepository {

    private static final BeanPropertyRowMapper<Meal> ROW_MAPPER = BeanPropertyRowMapper.newInstance(Meal.class);

    @Autowired
    private final JdbcTemplate jdbcTemplate;

    private final SimpleJdbcInsert insertMeals;

    @Autowired
    private final NamedParameterJdbcTemplate namedParameterJdbcTemplate;

    @Autowired
    protected JdbcMealRepository(JdbcTemplate jdbcTemplate, NamedParameterJdbcTemplate namedParameterJdbcTemplate) {
        this.insertMeals = new SimpleJdbcInsert(jdbcTemplate)
                .withTableName("meals")
                .usingGeneratedKeyColumns("id");

        this.jdbcTemplate = jdbcTemplate;
        this.namedParameterJdbcTemplate = namedParameterJdbcTemplate;
    }

    @Override
    public Meal save(Meal meal) {
        MapSqlParameterSource map = new MapSqlParameterSource()
                .addValue("id", meal.getId())
                .addValue("date_time", meal.getDatetime())
                .addValue("description", meal.getDatetime())
                .addValue("calories", meal.getCalories());

        namedParameterJdbcTemplate.update("INSERT INTO meals(id, date_time, description, calories) " +
                "VALUES(id=:id, date_time=:date_time, description=:description, calories=:calories)", map);

        return meal;
    }

}

Controller:

@Controller
public class JspMealController {
    @Autowired
    JdbcMealServiceImpl mealService;

    @GetMapping(value = "/list")
    public String getAll(Model model) {
        model.addAttribute("meals", mealService.getAll());
        return "meals";
    }

    @GetMapping(value = "/createForm")
    public String addForm(Model model) {
        Meal meal = new Meal();
        model.addAttribute("mealsCreate", meal);

        return "createmealForm";
    }

    @PostMapping(value = "/create")
    public String save(@ModelAttribute("mealsCreate") Meal meal) {
        mealService.save(meal);
        return "redirect:/list";
    }

    @GetMapping(value = "/delete")
    public String deleteMeal(@RequestParam("mealId") int id) {
        mealService.delete(id);
        return "redirect:/list";
    }

    @GetMapping(value = "/updateForm")
    public String updateForm(@RequestParam("mealId") int id, Model model) {
        Meal meal = mealService.get(id);
        model.addAttribute("mealsUpdate", meal);

        return "updatemealForm";
    }

    @PostMapping(value = "/update")
    public String update(@ModelAttribute("mealsUpdate") Meal meal) {
        mealService.update(meal);
        return "redirect:/list";
    }
}

JdbcMealRepository should not be an abstract class. We must provide a concrete implementation class. Try removing abstract keyword from JdbcMealRepository class.
