Spring 数据 JPA：如果在 jUnit 测试中使用多个配置 Class，则对象名称无效
Spring Data JPA: Invalid object name if use more than one Config Class in jUnit test
我在 运行 测试时收到 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);
}

FirmsRepossitory 看起来像：
@Repository
public interface FirmsRepository extends CrudRepository<FirmsEntity, FirmsEntityPK> {
@Modifying
@Transactional(propagation = Propagation.REQUIRES_NEW)
FirmsEntity save(FirmsEntity firmsEntity);
}
如果我在 @ContextConfiguration(classes = {OlmeFtpConfig.class} 中仅使用 OlmeFtpConfig.class，测试将毫无例外地执行。
但是在一些测试中（应用程序使用两个数据库）我需要使用两个配置 classes。每个配置中有不同的数据源 class.
如何运行测试无异常并在@ContextConfiguration注解中使用两个配置class？所以我需要springframework才能找到stg.FIRMS。
您提到您的配置中有两个 DataSource。很难猜测到底发生了什么，但听起来您实际上是在使用存储库访问错误的 DataSource。
有一个example how to properly setup Spring Data in case of multiple DataSources，应该会有帮助。
引用自述文件：
To connect to two databases we need to manually configure a DataSource, EntityManagerFactory and JpaTransactionManager.
下面是其中一组 bean 的配置，您必须根据测试中需要的设置进行调整，并且需要为具有不同 bean 名称的两个 DataSource 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 移到了单独的包中。
在OlmeCapConfig.class@EnableJpaRepositories注解中仔细指定basePackages:
@EnableJpaRepositories(basePackages={"com.pivotal.olme.cap_config",
"com.pivotal.olme.jpa.dao.cap",
"com.pivotal.olme.jpa.dao_impl.cap",
"com.pivotal.olme.jpa.entities.cap"},
entityManagerFactoryRef = "emFactoryCap",
transactionManagerRef = "txManagerCap")
我在 运行 测试时收到 SQLServerException：

@ContextConfiguration(classes = {OlmeFtpConfig.class, OlmeCapConfig.class}, loader = AnnotationConfigContextLoader.class)
