Java Spring数据JPA:如果在jUnit测试中使用多个配置类，则对象名称无效

运行测试时，我收到SQLServerException：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {OlmeFtpConfig.class, OlmeCapConfig.class}, loader = AnnotationConfigContextLoader.class)
public class FirmsRepositoryTest {

    @Autowired
    FirmsRepository firmsRepository;
    @Autowired
    ExtraDAO extraDAO;

    @Test
    public void save() throws Exception {

        int extraID = extraDAO.getMaxExtraID();

        FirmsEntity firmsEntity = new FirmsEntity();
            firmsEntity.setBoCode(DataGenerator.getNumberText(5));
            firmsEntity.setextraID(extraID);
            firmsEntity.setFirmShortName(DataGenerator.getNumberText(10));
            firmsEntity.setId(DataGenerator.getNumberBetween(9999,99999));

        FirmsEntity save = firmsRepository.save(firmsEntity);
        assertNotNull(save);


    }

完整堆栈跟踪是：

firmsrepository看起来像：

@Repository
public interface FirmsRepository extends CrudRepository<FirmsEntity, FirmsEntityPK> {

    @Modifying
    @Transactional(propagation = Propagation.REQUIRES_NEW)
    FirmsEntity save(FirmsEntity firmsEntity);


}

@存储库
公共接口FirmsRepository扩展了crudepository{
@修改
@事务性（传播=传播。需要\u新建）
坚定的拯救（坚定的坚定）；
}

如果我在

@ContextConfiguration（classes={OlmeFtpConfig.class}

中仅使用

OlmeFtpConfig.class

，测试将毫无例外地执行

但在一些测试中（应用程序使用两个数据库），我需要使用两个配置类

---

如何毫无例外地运行测试并在

@ContextConfiguration

注释中使用两个配置类？因此我需要

springframework

可以找到

stg.companys
您提到您的配置中有两个
数据源。很难猜测到底发生了什么，但听起来您很有效使用存储库主动访问错误的
数据源

有一种可能会有所帮助的方法

引用自述：

要连接到两个数据库，我们需要手动配置
数据源
、
EntityManager工厂
和
JpaTransactionManager

下面是其中一组bean的配置，您必须适应测试中需要的设置，并且需要为具有不同bean名称的两个
DataSource
s复制它

@Configuration
@EnableJpaRepositories(entityManagerFactoryRef = "customerEntityManagerFactory",
        transactionManagerRef = "customerTransactionManager")
class CustomerConfig {

    @Bean
    PlatformTransactionManager customerTransactionManager() {
        return new JpaTransactionManager(customerEntityManagerFactory().getObject());
    }

    @Bean
    LocalContainerEntityManagerFactoryBean customerEntityManagerFactory() {

        HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
        jpaVendorAdapter.setGenerateDdl(true);

        LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();

        factoryBean.setDataSource(customerDataSource());
        factoryBean.setJpaVendorAdapter(jpaVendorAdapter);
        factoryBean.setPackagesToScan(CustomerConfig.class.getPackage().getName());

        return factoryBean;
    }

    @Bean
    DataSource customerDataSource() {

        return new EmbeddedDatabaseBuilder().//
                setType(EmbeddedDatabaseType.HSQL).//
                setName("customers").//
                build();
    }
}

已解决：

我将一个Spring配置OlmeCapConfig.class移动到单独的包中
在OlmeCapConfig.class中，在@EnableJpaRepositories注释中仔细指定basePackages：

@EnableJpaRepositories（basePackages={“com.pivotal.olme.cap_config”


需要注意的是，没有必要为自动生成的代码（如Spring数据存储库）编写测试。Chrylis，它只是一个例子。Jens，是的，我有两个来自两个单独配置类的数据源：
OlmeFtpConfig.class
和
olmecaponfig.class
。我想使用一个jUnit测试中的两个不同的DB:
extra>DAO.getMaxextraID（）
使用来自
OlmeFtpConfig.class的数据源和
firmsRepository.save（firmsEntity）`使用来自
olmecaponfig.class的数据源。
"com.pivotal.olme.jpa.dao.cap",

"com.pivotal.olme.jpa.dao_impl.cap",

"com.pivotal.olme.jpa.entities.cap"},

entityManagerFactoryRef = "emFactoryCap",

transactionManagerRef = "txManagerCap")
