java - Spring 测试 DBunit 警告

Question

我正在使用 spring-test-dbunit，我在我的单元测试中收到警告消息:

代码:

@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 - Potential problem found: The configured data type factory 'class org.dbunit.dataset.datatype.DefaultDataTypeFactory' might cause problems with the current database 'MySQL' (e.g. some datatypes may not be supported properly). In rare cases you might see this message because the list of supported database products is incomplete (list=[derby]). If so please request a java-class update via the forums.If you are using your own IDataTypeFactory extending DefaultDataTypeFactory, ensure that you override getValidDbProducts() to specify the supported database products.

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());

在spring-test-dbunit中不知道如何解决这个问题。请帮忙。

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>
