我想对基于Spring Framework的RESTful API使用单元测试，我使用mysql来保存我的数据并使用PagingAndSortingRepository来实现我的RESTful API，这是我的测试代码：
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = SpringMvcApplication.class)
@WebAppConfiguration
public class CustomerRepositoryTests {
private MediaType contentType = new MediaType(MediaType.APPLICATION_JSON.getType(),
SUBTYPE);
private static final String SUBTYPE = "hal+json";
private MockMvc mockMvc;
@Autowired
private WebApplicationContext webApplicationContext;
@Autowired
private CustomerRepository customerRepository;
private long setupId;
@Before
public void setup() {
this.mockMvc = webAppContextSetup(webApplicationContext)
.apply(springSecurity())
.build();
customerRepository.deleteAll();
Customer customer = customerRepository.save(new Customer("userId", "my mobile", "my address", "my contactName"));
setupId = customer.getId();
}
@Test
//// FIXME: 6/26/16 Status Code is always 204, not 200!
public void changeCustomer() throws Exception {
mockMvc.perform(put("/api" + "/customers/{id}", setupId)
.content(TestUtil.objToJson(new Customer("my new userId", "my new mobile", "my new address", "my new contactName")))
.contentType(contentType))
.andExpect(status().isOk())
.andExpect(jsonPath("$.userId", is("my new userId")))
.andExpect(jsonPath("$.contactName", is("my new contactName")))
.andExpect(jsonPath("$.mobile", is("my new mobile")))
.andExpect(jsonPath("$.address", is("my new address")));
}
}
我的测试总是失败并说：
java.lang.AssertionError: Status
Expected :200
Actual :204
但是当我运行我的应用程序并使用如下命令时：
curl -X PUT -H "Content-Type:application/hal+json" -d '{ "userId": "Bilbo", "mobile": "Baggins", "contactName":"my new contact", "address":"new address" }' http://localhost:8080/api/customers/1
我的服务器返回状态代码200并成功更新数据。 我搜索了一会儿却对此一无所知。
编辑： 这是我的CustomerRepository：
public interface CustomerRepository extends PagingAndSortingRepository<Customer, Long> {
}
客户：

@Table(name = "customer")
public class Customer {
@Id

看起来测试使用默认配置，根据Spring Data REST - Reference Documentation
返回204 No Content
对于公开的资源，我们使用一组默认状态代码：
200 OK - 对于普通的GET请求。
201 Created - 用于创建新资源的POST和PUT请求。
204 No Content - 如果配置设置为不返回资源的响应主体，则为PUT，PATCH和DELETE请求 更新（RepositoryRestConfiguration.returnBodyOnUpdate）。如果 配置值设置为包括PUT的响应，200 OK即可 返回更新，201将为资源返回Created 通过PUT创建。
如果配置值 （RepositoryRestConfiguration.returnBodyOnUpdate和 RepositoryRestConfiguration.returnBodyCreate）被显式设置为 null，将使用HTTP Accept标头的存在来确定 响应代码。
