我正在尝试使用DBUnit,从不同的配置文件(不同的项目)加载多个数据库.

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：

java.lang.IllegalStateException: Unable to find a DB Unit database connection,missing one the following beans: [dbUnitDatabaseConnection,dataSource]

任何人都知道为什么DBunit没有找到连接？
