收到错误，构造函数的参数0需要一个bean，但是找到了2个，但其中一个“找到的” bean被我删除了]]

Question

我正在尝试使用jpa / jdbc建立h2数据库，在使用jpa而不是jdbc为查询接口创建了一个隐含符号后，我现在得到了错误：

com.nsa.charitystarter.service.CharityQueries中的构造函数的参数0需要一个bean，但是找到了2个：-charityRepoJDBC：定义在文件[C：\ Users \ V La Roche \ Desktop \ assessment-1-starter \ out \ production \ classes \ com \ nsa \ charitystarter \ data \ CharityRepoJDBC.class]中-charityRepoJPA：定义为null

不确定什么地方出了问题，也不确定从这里到哪里去，我还没办法在网上找到很多与我有类似问题的人。

我使用jdbc的实现

@Repository
public class CharityRepoJDBC implements CharityRepository {

    private JdbcTemplate jdbc;
    private RowMapper<Charity> charityMapper;

    @Autowired
    public CharityRepoJDBC(JdbcTemplate aTemplate) {
        jdbc = aTemplate;


        charityMapper = (rs, i) -> new Charity(
                rs.getLong("id"),
                rs.getString("name"),
                rs.getString("registration_id"),
                rs.getString("acronym"),
                rs.getString("purpose")
        );
    }

    @Override
    public List<Charity> findCharityBySearch(String searchTerm) {

        String likeSearch = "%" + searchTerm + "%";

        return jdbc.query(
                "select id, acronym, name, purpose, logo_file_name, registration_id  " +
                        "from charity " +
                        "where concat(name, acronym, purpose, registration_id) like ?",
                new Object[]{likeSearch},
                charityMapper);
    }

    @Override
    public Optional<Charity> findById(Long id) {
        return Optional.of(
                jdbc.queryForObject(
                        "select id, acronym, name, purpose, logo_file_name, registration_id  from charity where id=?",
                        new Object[]{id},
                        charityMapper)
        );
    }
}
慈善发现者实施：

@Service
public class CharityQueries implements CharityFinder {
    private CharityRepository charityRepository;


    public CharityQueries(CharityRepository repo) {
        charityRepository = repo;
    }

    public Optional<Charity> findCharityByIndex(Integer index) {
        return charityRepository.findById(index.longValue());
    }

    public List<Charity> findCharityBySearch(String searchTerm) {

        return charityRepository.findCharityBySearch(searchTerm);
    }
}
CharityFinder界面

public interface CharityFinder {

    public Optional<Charity> findCharityByIndex(Integer index);

    public List<Charity> findCharityBySearch(String searchTerm);

}

您目前具有以下定义，

Answer 2

您似乎在类路径上有Spring Data JDBC入门，而Spring Data JPA入门有。
