春季测试 DBunit 警告

【中文标题】春季测试 DBunit 警告【英文标题】：Spring Test DBunit Warning 【发布时间】：2015-02-23 12:05:22 【问题描述】：我正在使用 spring-test-dbunit，我在单元测试中收到一条警告消息：
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 - 潜力 发现问题：配置的数据类型工厂'class org.dbunit.dataset.datatype.DefaultDataTypeFactory' 可能会导致 当前数据库“mysql”的问题（例如，某些数据类型可能 没有得到适当的支持）。在极少数情况下，您可能会看到此消息 因为支持的数据库产品列表不完整 （列表=[德比]）。如果是这样，请通过 论坛。如果您使用自己的 IDataTypeFactory 扩展 DefaultDataTypeFactory，确保覆盖 getValidDbProducts() 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。

【参考方案1】：问题解决了。 我将以下配置添加到 applicationContext.xml (context.xml) 中。
<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>

【参考方案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;
【讨论】：
并确保所有 bean 名称，即方法名称与上面提到的 @Yser 完全相同...【参考方案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（在将由 autoconfig 选择的包中）：
@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;
