 单元测试类：

@ContextConfiguration(locations = {"classpath:spring/common/dataSource.xml","classpath:spring/common/applicationContext.xml",
		"classpath:spring/car/car.xml","classpath:spring/car/car-dao.xml",
		"classpath:spring/biap/biap.xml","classpath:spring/biap/biap-dao.xml"})
public abstract class BaseTest extends AbstractTransactionalJUnit4SpringContextTests {
       //自动装配默认是根据类型类匹配的,用@Qualifier 可以指定具体的数据源
       @Autowired
	public void setDataSource(@Qualifier("car_dataSource") DataSource dataSource) {
		this.simpleJdbcTemplate = new SimpleJdbcTemplate(dataSource);
	}

}
public class BasedaoTest extends BaseTest{
	@Resource(name="carBaseDAO")
	BaseDAO carBaseDAO;
	private String namespace="car_type.";
	@Test
	public void batchDelete() {
		List list=new ArrayList();
		for (int i=2;i<10;i++) {
			list.add(i);
		}
		this.carBaseDAO.batchDelete(namespace, "deleteCarType", list);
	}
} 

 运行之后报错

 经过断点跟踪调试：

 

org.springframework.test.context.transaction.TransactionalTestExecutionListener

private TransactionConfigurationAttributes retrieveTransactionConfigurationAttributes(Class clazz) {
		Class annotationType = TransactionConfiguration.class;
		TransactionConfiguration config = clazz.getAnnotation(annotationType);
		if (logger.isDebugEnabled()) {
			logger.debug("Retrieved @TransactionConfiguration [" + config + "] for test class [" + clazz + "]");
		}

		String transactionManagerName;
		boolean defaultRollback;
		if (config != null) {
			transactionManagerName = config.transactionManager();
			defaultRollback = config.defaultRollback();
		}
		else {
			transactionManagerName = (String) AnnotationUtils.getDefaultValue(annotationType, "transactionManager");
			defaultRollback = (Boolean) AnnotationUtils.getDefaultValue(annotationType, "defaultRollback");
		}

		TransactionConfigurationAttributes configAttributes =
				new TransactionConfigurationAttributes(transactionManagerName, defaultRollback);
		if (logger.isDebugEnabled()) {
			logger.debug("Retrieved TransactionConfigurationAttributes [" + configAttributes + "] for class [" + clazz + "]");
		}
		return configAttributes;
	}

 

 

 默认它会加上事务，事务管理默认的bean名称是transactionManager,因为配置中没有这个bean 的配置,所以抛出异常，这个        TransactionConfiguration config = clazz.getAnnotation(annotationType);
我们没有在测试类上注释，所以为null，去取默认的transactionManager。

我们可以这样做

@TransactionConfiguration(transactionManager="car_transactionManager")
public class BasedaoTest extends BaseTest{

}
