Spring Test DBunit警告

Question

我正在使用spring-test-dbunit,我在单元测试中收到一条警告:

码:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/context.xml"})
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
    DirtiesContextTestExecutionListener.class,
    TransactionalTestExecutionListener.class,
    DbUnitTestExecutionListener.class })
public class TestDB {

    @Autowired 
    private ICourseService courseService;

    @Test
    @DatabaseSetup("sampleData.xml")
    public void testFind() throws Exception {
        List<Course> courseList = this.courseService.getAllCourses();

        assertEquals(1, courseList.size());
        assertEquals("A001", courseList.get(0).getCourseNumber());
    }

}

警告:

1093 [main] WARN org.dbunit.dataset.AbstractTableMetaData - 发现潜在问题:配置的数据类型factory'class org.dbunit.dataset.datatype.DefaultDataTypeFactory'可能导致当前数据库'MySQL'出现问题(例如某些数据类型可能不会得到适当支持).在极少数情况下,您可能会看到此消息,因为受支持的数据库产品列表不完整(list = [derby]).如果是这样,请通过论坛请求java级更新.如果您使用自己的IDataTypeFactory扩展DefaultDataTypeFactory,请确保覆盖getValidDbProducts()以指定支持的数据库产品.

当我使用没有spring-test-dbunit的DBunit时,问题可以解决如下:

  Connection jdbcConnection = DriverManager.getConnection( "jdbc:mysql://localhost/test", "root", "root");
        IDatabaseConnection connection = new DatabaseConnection(jdbcConnection);
        connection.getConfig().setProperty(DatabaseConfig.PROPERTY_DATATYPE_FACTORY, new MySqlDataTypeFactory());
        connection.getConfig().setProperty(DatabaseConfig.PROPERTY_METADATA_HANDLER, new MySqlMetadataHandler());

我不知道如何在spring-test-dbunit中解决这个问题.请帮忙.

Answer 1

问题解决了.我将以下配置添加到applicationContext.xml(context.xml).

<property name="location">
        <value>classpath:jdbc.properties</value>
    </property> 
</bean>  

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="${driver}" />
    <property name="url" value="${url}" />
    <property name="username" value="${username}" />
    <property name="password" value="${password}" />
</bean>

<bean id="sqlDataTypeFactory" class ="org.dbunit.ext.mysql.MySqlDataTypeFactory" />

<bean id="dbUnitDatabaseConfig" class="com.github.springtestdbunit.bean.DatabaseConfigBean">
     <property name = "datatypeFactory" ref = "sqlDataTypeFactory" />
</bean> 
<bean id="dbUnitDatabaseConnection" class="com.github.springtestdbunit.bean.DatabaseDataSourceConnectionFactoryBean">
    <property name="databaseConfig" ref="dbUnitDatabaseConfig"/>
    <property name="dataSource" ref="dataSource" />
</bean>

Answer 2

只是想添加与Java Config相同的解决方案:

@Bean
public DataSource dataSource() {
    DataSource dataSource = ...
    return dataSource;
}

@Bean
public DatabaseConfigBean dbUnitDatabaseConfig() {
    DatabaseConfigBean dbConfig = new com.github.springtestdbunit.bean.DatabaseConfigBean();
    dbConfig.setDatatypeFactory(new org.dbunit.ext.h2.H2DataTypeFactory());
    return dbConfig;
}

@Bean
public DatabaseDataSourceConnectionFactoryBean dbUnitDatabaseConnection() {
    DatabaseDataSourceConnectionFactoryBean dbConnection = new com.github.springtestdbunit.bean.DatabaseDataSourceConnectionFactoryBean(dataSource());
    dbConnection.setDatabaseConfig(dbUnitDatabaseConfig());
    return dbConnection;
}

Answer 3

为了补充现有的答案，我只想使用 Spring Boot 配置的数据源在 Spring Boot 上下文中添加对我有用的内容。在您的测试源中添加以下类（在一个将由 autoconfig 选取的包中）：

@Configuration
public class DBUnitConfig {

    @Autowired
    private DataSource dataSource;

    @Bean
    public DatabaseDataSourceConnectionFactoryBean dbUnitDatabaseConnection() {
        DatabaseConfigBean bean = new DatabaseConfigBean();
        bean.setDatatypeFactory(new H2DataTypeFactory());

        DatabaseDataSourceConnectionFactoryBean dbConnectionFactory = new com.github.springtestdbunit.bean.DatabaseDataSourceConnectionFactoryBean(dataSource);
        dbConnectionFactory.setDatabaseConfig(bean);
        return dbConnectionFactory;
    }
}
