Question

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：

@Entity
@Table(name = "customer")
public class Customer {
    @Id
    @GeneratedValue()
    private Long id;

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "created", nullable = false)
    private Date created;

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "updated", nullable = false)
    private Date updated;

    @Version
    @JsonIgnore
    private Long version;

    @NotNull

    public Customer() {}

看起来测试使用默认配置，根据Spring Data REST - Reference Documentation

返回204 No Content

5.1.1. Default status codes

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。

使用MockMVC测试Spring RESTful put方法失败
