单元测试代码：SpringTest+JUnit

}

----需要配置2个bean，测试Controller需要用到

<bean
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
</bean>
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
</bean>

测试Service(Dao类似)

/**
* 这种方式 的单元测试，不需要重复指定 资源文件，减少重复。 麻烦的地方在于，需要手动获取bean。
*
* @author leiwen@fansunion.cn
*/
public class FansUnionServiceTest extends JUnitTestBase {

private static CampaignGroupService campaignGroupService = context
.getBean(CampaignGroupService.class);

// 测试add,remove,update方法的时候，已经测试了find？
@Test
public void addCampaignGroup() {
CampaignGroup cg = buildOneGroup();

campaignGroupService.add(cg);

CampaignGroup dbCampaignGroup = campaignGroupService.find(cg.getId());
Assert.assertEquals(cg, dbCampaignGroup);
campaignGroupService.delete(cg.getId());
}

基于注解的测试

/**

@ContextConfiguration(locations = { "classpath:spring-mvc-context.xml",

@Autowired
private CampaignGroupService campaignGroupService;

/**
* 根据campaignId获取campaignGroup的name集合<br>
* 测试场景：<br>
*
*/
@Test
public void testListCampaignGroupNameByCampaignId(){
System.out.println("**********");
System.out.println(campaignGroupService.listCampaignGroupNameByCampaignId(1005899));
}
