老师,在spring.xml文件中已经配置扫描注解 为什么运行测试时，还报这个错误

问一下同学数据库的配置是写在applicationContext.xml中的吗？建议同学使用如下的代码再试试呢？

<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd">
    <import resource="applicationContext.xml"/>
    <context:component-scan base-package="com.imooc.os.service.impl2"/>
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">
        <property name="transactionManager" ref="transactionManager"/>
    </bean>
</beans>

或者同学下载老师的源码，对照一下再试试。

祝：学习愉快~

这是spring-service-impl1.xml中的配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:context="http://www.springframework.org/schema/context"
      xmlns:aop="http://www.springframework.org/schema/aop"
      xmlns:tx="http://www.springframework.org/schema/tx"
      xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

   <import resource="applicationContext.xml"></import>

   <!--配置事务管理器-->
   <bean id="ptm" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
       <property name="dataSource" ref="dataSource"></property>
    </bean>
   <!--配置事务定义-->
   <bean id="td" class="org.springframework.transaction.support.DefaultTransactionDefinition">
   </bean>

   <!--扫描impl1包-->
   <context:component-scan base-package="com.imooc.os.service.impl1" />
</beans>

这是测试类:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring-service-impl1.xml")
public class OrderTest {
   @Autowired
   private OrderService orderService;
   @Test
   public void testAddOrder(){
       Order order = new Order("100006","100002",3,1599,"xiaoxiao","","");
       orderService.addOrder(order);

   }
}
