java - DBUnit 测试给出了 MariaDB 的 NoSuchColumnException

Question

值得注意的是，这些测试在 Ubuntu 和服务器上完美运行，但在 Mac 和 Windows 上失败并出现相同的错误。

因此，在我的测试中，我使用此配置连接到 Maria 数据库:

@Configuration
public class EmbeddedDatabase {

    @Autowired
    private String defaultSchema;

    @Bean
    public MariaDB4jService mariaDB4jService() {
        MariaDB4jSpringService mariaDB4jSpringService = new MariaDB4jSpringService();

        DBConfigurationBuilder config = mariaDB4jSpringService.getConfiguration();
        config.setPort(3310);

        return mariaDB4jSpringService;
    }

    @Bean
    public DataSource dataSource(MariaDB4jService mariaDB4jService) throws Exception {
        mariaDB4jService.getDB().createDB(defaultSchema);

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUrl(mariaDB4jService.getConfiguration().getURL(defaultSchema));
        dataSource.setUsername("root");
        dataSource.setPassword("");
        dataSource.setDriverClassName("org.mariadb.jdbc.Driver");

        return dataSource;
    }
}

现在，默认架构已在我的 xml 配置文件中设置，它是:

<bean id="dbUnitDatabaseConnection" class="com.github.springtestdbunit.bean.DatabaseDataSourceConnectionFactoryBean" 
    <property name="schema" ref="defaultSchema" />
    <property name="dataSource" ref="dataSource"/>
</bean>
<bean id="defaultSchema" class="java.lang.String">
    <constructor-arg type="java.lang.String" value="test"/>
</bean>

这是所有测试类的父类:

@ContextConfiguration("classpath:test-repository-config.xml")
@TestExecutionListeners({ DbUnitTestExecutionListener.class })
@DbUnitConfiguration(dataSetLoader = RepositoryFlatXmlDataSetLoader.class)
public abstract class AbstractRepositoryTest 
    extends AbstractTransactionalJUnit4SpringContextTests {

}

我有这个自定义 RepositoryFlatXmlDataSetLoader 用于替换我在 xml 数据集中使用的“[NULL]”字段:

public class RepositoryFlatXmlDataSetLoader extends AbstractDataSetLoader {
    private static Logger logger = LoggerFactory.getLogger(RepositoryFlatXmlDataSetLoader.class);
    @Override
    protected IDataSet createDataSet(Resource resource) throws Exception {
        FlatXmlDataSetBuilder builder = new FlatXmlDataSetBuilder();
        builder.setColumnSensing(true);

        try (InputStream inputStream = resource.getInputStream()) {
            return createReplacementDataSet(builder.build(inputStream));            
        }
        catch(Throwable thrh){
            logger.error("Failed to create dataset");
            throw thrh;
        }
    }

    private ReplacementDataSet createReplacementDataSet(FlatXmlDataSet dataSet) {
        ReplacementDataSet replacementDataSet = new ReplacementDataSet(dataSet);

        //Configure the replacement dataset to replace '[null]' strings with null.
        replacementDataSet.addReplacementObject("[null]", ITable.NO_VALUE);
        replacementDataSet.addReplacementObject("[NULL]", ITable.NO_VALUE);

        return replacementDataSet;
    }
}

这是我的数据集 xml 文件之一 - officeRepositoryData.xml:

<dataset>
    <cfr_office ID="1" ORG_NAME="demo" IS_DEFAULT="true"/>
    <cfr_office ID="2" ORG_NAME="test" IS_DEFAULT="false"/>
</dataset>

例如，这是测试之一:

@NotThreadSafe
@DatabaseSetup(value = "officeRepositoryData.xml", type = DatabaseOperation.CLEAN_INSERT)
@DatabaseTearDown(value = "officeRepositoryData.xml", type = DatabaseOperation.DELETE_ALL)
public class OfficeRepositoryTest extends AbstractRepositoryTest {

    @Autowired
    private OfficeRepository officeRepository;

    @Test
    public void testDefaultOfficeFound() {
        List<Office> offices = officeRepository.findDefault();

        assertTrue(isNotEmpty(offices));

        Office office = offices.get(0);
        assertEquals("demo", office.getOrganizationName());
        assertTrue(office.getIsDefault());
    }
}

那么，当我运行测试时会发生什么...... 所有表都是在 JPA 中创建的，我在 eclipse 控制台和创建了 MariaDB 连接的数据库透视图中看到它，然后当 dbUnit 开始为测试准备数据集时，我收到错误。这是它的堆栈跟踪以及之前的一些行，这些行可能很重要(或不重要，不确定):

通常，出现此类错误的原因是该列在某处丢失，或者该列存在一些区分大小写的问题，我在代码中进行了深入调试，在我看来，对于这种特殊情况，我遇到了一些其他问题。但我不确定。

看起来dbUnit在代码深处创建了一些columnList，从一些结果集中获取有关数据库的一些信息。如果所有信息都与目录、schema_name 和 table_name 匹配，则感觉此列列表包含列值。但在调试中 shema_name 为 null，因此无法创建列列表，然后无法找到第一列 - 即 ID。 如果我写的最后一段很乱，请不要计较。

Answer 1

我会尝试使用小写的列名称:

<dataset>
    <cfr_office id="1" org_name="demo" is_default="true"/>
    <cfr_office id="2" org_name="test" is_default="false"/>
</dataset>
