【中文标题】DBUnit 错误 - 缺少以下 bean 之一：[dbUnitDatabaseConnection, dataSource]

【英文标题】：DBUnit error - missing one the following beans: [dbUnitDatabaseConnection, dataSource]

【问题描述】：

我正在尝试将 DBUnit 与从不同配置文件（不同项目）加载的多个数据库一起使用。

在我的 Foo @Configuration 文件中，我有以下 bean：

@Bean(name="dataSourceFoo")
public DataSource dataSourceFoo() 
    BasicDataSource dataSource = new BasicDataSource();
    ...
    return dataSource;

在我的 Bar @Configuration 文件中，我有以下 bean：

@Bean(name="dataSourceBar")
public DataSource dataSourceBar() 
    BasicDataSource dataSource = new BasicDataSource();
    ...
    return dataSource;

在第三个项目中，我的测试文件如下所示：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = ThirdProjectAppContextConfig.class)
@TestExecutionListeners( DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class,
        DbUnitTestExecutionListener.class )
@DatabaseSetups(
        @DatabaseSetup(connection = "dataSourceFoo", value = "classpath:db/FooTest.xml"),
        @DatabaseSetup(connection = "dataSourceBar", value = "classpath:db/BarTest.xml") )
@TestPropertySource("/application.properties")
@DirtiesContext
@Transactional
public class FooBarTest 

    @Autowired
    private Service service;

    @Test
    public void test()
        service.callFooBar();
        ...
    

当我运行测试时，它会抛出以下错误：

有人知道为什么 DBunit 没有找到连接吗？

【参考方案1】：

com.github.springtestdbunit.DbUnitTestExecutionListener.prepareTestInstance(DbUnitTestContextAdapter) 正在寻找数据库配置，而我定义的那些没有找到，dbunit 默认使用“dataSource”。将以下配置放在测试类上即可解决问题：

@DbUnitConfiguration(databaseConnection="dataSourceFoo","dataSourceBar")
