Spring 单元测试出错 NoSuchBeanDefinitionException? 报错

Spring 单元测试出错 NoSuchBeanDefinitionException? 400 报错

问题：程序可以正常启动并运行，但单元测试时则出错

出错提示：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.gwzyh.finance.services.InvestorService] 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)}

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={
	"classpath*:springmvc-servlet.xml"
})
@Transactional
public class InvestorServiceTest {
		
    @Autowired
    private InvestorService investorService;
		
    @Test
    public void investorServiceShouldBeInjected() {
	Assert.assertNotNull(investorService); 
    }
	
}
