我正在尝试为使用Spring MVC 3.1.1创建的Restful API服务器构建一组单元/集成测试.

我正在尝试使用Spring-test-mvc.

我是Spring的新手,因此是spring-test-mvc.

我将包含我的代码的相关部分,让您了解我的结构：

PurchaseController：

@Controllerpublic class PurchaseController{        @autowired    private IPurchaseService purchaseService;    @RequestMapPing(value = "purchases",method = RequestMethod.GET)    @ResponseBody    public final List

PurchaseService：

@Servicepublic class PurchaseService implements IPurchaseService{    @autowired    private IPurchaseDAO purchaseDAO;    public PurchaseService()    {    }    @Transactional    public List

PurchaseDAO：

@Repositorypublic class PurchaseDAO extends AbstractJpaDAO

AbstractJpaDAO：

public abstract class AbstractJpaDAO

这是我的控制器测试：

public class PurchaseControllerTest extends AbstractControllerTest{    @autowired    private IPurchaseService purchaseService;    @autowired    private PurchaseController purchaseController;    private mockmvc mockmvc;    @Before    public voID setup()    {        // Test Purchase        Purchase purchase = new Purchase();        purchase.setPan(5412311111111121l);        purchase.setCvc((short) 122);        purchase.setExpiry("1215");        purchase.setMerchantname("TestMerchant");        purchase.setMerchantType("Airline");        purchase.setTransactionAmount(new BigDecimal("300.99"));        mockmvc = mockmvcBuilders.standalonesetup(purchaseController).build();        purchaseService.addPurchase(purchase);    }    @Test    public voID testGetAll() throws Exception    {        this.mockmvc                .perform(get("/purchase").accept(MediaType.APPliCATION_JsON))                .andExpect(status().isOk())                .andExpect(content().type(MediaType.APPliCATION_JsON));    }}

AbstractControllerTest：

@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(classes = {ControllerTestConfig.class},loader=AnnotationConfigContextLoader.class)@ActiveProfiles("test")public class AbstractControllerTest{}

ControllerTestConfig：

@Configuration@Profile("test")public class ControllerTestConfig {    @Beanpublic PurchaseService purchaseService(){    return new PurchaseService();}@Beanpublic PurchaseDAO purchaseDAO(){    return new PurchaseDAO();}@Beanpublic EntityManagerFactory entityManager(){    return new LocalEntityManagerfactorybean().getobject();}}

通过Eclipse的JUnit运行我的测试时出现以下错误：

关于为什么我的PurchaseService没有被创建和注入的任何想法？

UPDATE

所以我将我的购买服务Bean添加到ControllerTestConfig …现在我收到有关我的purchaseDAO的错误.

如何将其添加到ControllerTestConfig中？是否必须嵌套在购买Bean中？

我将PurchaseDAO bean添加到ControllerTestConfig.

更新2

所以现在我将一个EntityManagerFactory Bean添加到我的ControllerTestConfig后得到一个空指针异常！

有任何想法吗？
谢谢最佳答案这不起作用,因为spring-test-mvc不会从Junit的ContextConfiguration中选择上下文配置,而是可以执行此 *** 作(假设您的Service Bean正在通过ControllerTestConfig配置在某处加载)：
