多数据源使用spring test

正确做法：
1.基础Test类

@ContextConfiguration(locations={"classpath:applicationContext.xml"})
@TransactionConfiguration(defaultRollback=false)
public class TestBase extends AbstractTransactionalJUnit4SpringContextTests{

@Override
@Resource(name="gameDataSource")
public void setDataSource(DataSource dataSource) {
super.setDataSource(dataSource);
}

}

2.继承的类

@TransactionConfiguration(transactionManager="gameTransactionManager",defaultRollback=false)
public class MenuBoTest extends TestBase{

@Autowired
private MenuInfoBo menuInfoBo;

@Test
public void test(){
MenuInfo menuInfo=new MenuInfo();
menuInfo.setMenuName("本地游戏");
menuInfo.setMenuOpenType(1);
menuInfo.setMenuOrder(1);
menuInfoBo.add(menuInfo);
}

}

遇到的问题：
1.继承类MenuBoTest开始没有配注解@TransactionConfiguration
执行的时候会报错 显示No bean named 'transactionManager' is defined

源代码如下
private TransactionConfigurationAttributes retrieveTransactionConfigurationAttributes(Class<?> clazz) { 
        Class<TransactionConfiguration> 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; 
    } 

执行的时候默认会加上事务，事务的bean是transactionManager，因为配置中没有这个bean所以会抛出这个异常。解决办法就是在继承类上加上注解@TransactionConfiguration(transactionManager="gameTransactionManager")，使用配置已经配过的这个gameTransactionManager。

2.经过上面的步骤测试又出现问题，可以查询但是不能进行增删改的操作，猜测原因可能是事务回滚造成的，所以在继承类加上defaultRollback=false，重新测试成功。
