测试类中NamedParameterJdbcTemplate的NoSuchBeanDefinitionException异常

Question

我在spring boot应用程序中使用JDBCTemplate运行单元测试时遇到问题。我有以下配置代码：

@Configuration
@ComponentScan("com.idoc.recon.persistence")
public class SpringJDBCConfig {

    @Value("${spring.datasource.url}")
    private String url;
    @Value("${spring.datasource.username}")
    private String username;
    @Value("${spring.datasource.password}")
    private String password;


    @Value("${spring.datasource.driver-class-name:oracle.jdbc.pool.OracleDataSource}")
    private String driverClassName;

    @Bean(name = "OracleUniversalConnectionPool")
    @Primary
    public DataSource getDataSource() {
        PoolDataSource dataSource = null;
        try {
            dataSource = PoolDataSourceFactory.getPoolDataSource();
            dataSource.setConnectionFactoryClassName(driverClassName);
            dataSource.setURL(url);
            dataSource.setUser(username);
            dataSource.setPassword(password);
            dataSource.setFastConnectionFailoverEnabled(true);
            dataSource.setInitialPoolSize(5);
            dataSource.setMinPoolSize(5);
            dataSource.setMaxPoolSize(10);
        } catch (SQLException ea) {
            System.err.println("Error connecting to the database: " + ea.getMessage());
        }
        return dataSource;
    }

这是存储库类：

@Repository
public class CompanyRepositoryImplementation implements CompanyRepository {
    
    protected final Log logger = LogFactory.getLog(CompanyRepositoryImplementation.class);
    
    @Autowired
    private NamedParameterJdbcTemplate jdbcTemplate;

    @Override
    public long createMdCompany(CreateCompanyRequest company) throws DaoException { stuff..}
}

例如，通过从邮递员那里调用Rest服务就可以实现这一点。我编写这个单元测试只是为了测试存储库部分：

@ExtendWith(SpringExtension.class)
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@ContextConfiguration(classes = {
        com.idoc.recon.persistence.dao.interfaces.implementations.CompanyRepositoryImplementation.class,
        com.idoc.recon.persistence.dao.configuration.SpringJDBCConfig.class })
public class CompanyRepositoryTest {

    @Autowired
    CompanyRepository companyRepository;

    @Test
    public void createMdCompanyTest() {stuff..}
}

但是当我运行junit测试时，我收到了以下错误：

有人能帮我找出缺了什么吗？

Answer 1

使用带有数据源参数的setter添加@Autowired：

private NamedParameterJdbcTemplate namedParameterJdbcTemplate;

@Autowired
public void setDataSource(DataSource dataSource) {
    this.namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
}
