项目经验之springmvc单元测试

@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {NoticeServiceConfig.class})

错误情况：在NoticeServiceConfig类中如下：

@ComponentScan({"com.xx.xx.notice"})@EnableJpaRepositories( basePackages = {"com.xx.xx.common.repository"})@ImportResource("classpath:datasource_mysql.xml")

报错：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.xx.xx.notice.repository.WeixinSenderRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

究其原因是因为我的dao层接口实现了JpaRepository接口，如果在单元测试中，就必须要引入该dao层所在的package,通过@EnableJpaRepositories指定到相应的包就可以，重点在于使用该注解，不能与@ComponentScan扫描的包的路劲重合，否则会提示：

Could not autowire. There is more than one bean of 'WeixinSenderRepository' type. Beans:weixinSenderRepository,weixinSenderRepository.
