Spring的JUnit错误：NoSuchBeanDefinitionException: No unique bean of type,expected single matching bean but found 2 [dataSource1,data

当配置文件中有两个spring datasource时，利用Spring的JUnit测试会报如下错误：

NoSuchBeanDefinitionException: No unique bean of type,expected single matching bean but found 2 [dataSource1,dataSource2]

 

测试类的annotation如下：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/applicationContext-resources.xml"})
@TransactionConfiguration(transactionManager = "txManager", defaultRollback = true)
@Transactional
public class MyTest extends AbstractTransactionalJUnit4SpringContextTests {

    ......

}
   
原因是：不知道注入哪个数据源，改成一个数据源即可
<alias name='dataSource' alias='dataSource1'/>
<alias name='dataSource' alias='dataSource2'/>
