我是Spring MVC和JUnit的新手。基本上我想自動裝載服務類,這個類應該在春天的環境中加載。Spring 3和JUnit 4(自動裝配)
服務
@Service public class FundService { @Autowired FundDAO fundDAO; /** * @return */ public List getFundDetails(String productId) { return fundDAO.getFundDetails(productId); } }
應用上下文
<beans>
<mvc:annotation-driven />
<context:component-scan base-package="com.test.*" />
</beans>
JUnit類
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"classpath*:/WEB-INF/application-context.xml"}) public class CompensationServiceTest { @Autowired private FundService fundService; @Test public void verifyGetCompensationList() { System.out.println(fundService == null); } }
在執行我得到以下異常跟蹤測試
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.test.admin.service.CompensationServiceTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.test.admin.service.FundService com.test.admin.service.CompensationServiceTest.fundService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.test.admin.service.FundService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

@Service也可以做同樣的事情。就像組件一樣,它也是立體聲類型之一。 – Ritesh 2012-08-17 09:44:27
