Question

我使用Spring Initializer，嵌入式Tomcat，Thymeleaf模板引擎和包作为可执行的JAR文件生成了一个Spring Boot Web应用程序。

使用的技术：

Spring Boot 2.0.0.M6，Java 8，maven

我有这个配置文件

@Configuration
@Profile("prod")
@EnableTransactionManagement /* Defines a Bean Post-Processor (proxies @Transactional bean) */
public class PersistenceConfig {
@Bean 
    public MetricsRepository metricsRepository() {
        return new JdbcMetricsRepository();
    }
]

在应用程序中。我有这项服务，工作正常

@Service
public class ExcelService {

    @Autowired
    MetricsRepository jdbcMetricsRepository;
..
}

我也有这个Junit测试：

@ContextConfiguration(classes={PersistenceConfig.class})
@RunWith(SpringRunner.class)
public class JdbcMetricsRepositoryTests {

    @Autowired
    MetricsRepository jdbcMetricsRepository;

    @Test
    public void testGetHotelReservations() throws DataAccessException, SQLException {

        jdbcMetricsRepository.getHotelReservations();


    }

}

但是在运行测试时我遇到了这个错误：

Error creating bean with name 'com.iberia.repository.JdbcMetricsRepositoryTests': Unsatisfied dependency expressed through field 'jdbcMetricsRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.iberia.repository.MetricsRepository' available: expected at least 1 bean which qualifies as autowire candidate.

您应该将@SpringBootTest注释添加到测试类中。

@SpringBootTest
@ContextConfiguration(classes={PersistenceConfig.class})
@RunWith(SpringRunner.class)
public class JdbcMetricsRepositoryTests {

在Spring Boot 2.0.0.M6中运行Junit测试时出错
