DBUnit测试为MariaDB提供NoSuchColumnException

重要的是要注意这些测试在Ubuntu和服务器上运行良好，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 db：

@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，我的xml配置文件中设置了默认架构，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>

以下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 {

}

我有这个自定义的RepositoryFlatXmlDataSetLoader用于替换＆＃34; [NULL]＆＃34;我在xml数据集中使用的字段：

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，这是其中一项测试：

@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DB Perspective中看到它创建了MariaDB连接，然后当dbUnit开始为测试准备数据集时，我得到一个错误。这是它的堆栈跟踪，其中一些先前的行可能很重要（或不是，不确定）：

通常对于这样的错误，原因是列错过某处或列有一些区分大小写问题，我在代码中进行了深度调试，而且在我看来，对于这个特殊情况我遇到了一些其他问题。但我不确定。

看起来深入代码dbUnit会创建一些columnList，从某些resultSet获取有关db的一些信息。如果所有信息都与catalog，schema_name和table_name匹配，则会感觉此列列表中包含列值。但是shema_name在调试中为null，因此无法创建列列表，然后无法在那里找到第一列 - 即ID。 如果我写的最后一段是一团糟，不要把它计算在内。

1 个答案:

答案 0 :(得分：0)

我会尝试使用小写列名：

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