 单元测试类：

        //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

         this.simpleJdbcTemplate = new SimpleJdbcTemplate(dataSource);
     }

 }

 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{

 }
