使用MockMVC測試Spring RESTful put方法失敗

Question

我想對基於Spring Framework的RESTful API使用單元測試，我使用mysql保存數據，並使用PagingAndSortingRepository與RESTful API一起實現，這是我的測試代碼：

    @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")));
        }
}

我的測試總是失敗，並說：

    java.lang.AssertionError: Status 
    Expected :200
    Actual   :204

但是當我運行我的應用程序並使用如下命令時：

     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

我的服務器返回狀態碼200並成功更新數據。 我搜索了一段時間，但對此一無所知。

編輯 ：這是我的CustomerRepository：

    public interface CustomerRepository extends PagingAndSortingRepository<Customer, Long> {
    }

顧客：

@Data
@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
    private String userId;

    //TODO: Limit type to 1, 2, 3 or 4
    private int type;

    private String companyName;

    private String phone;

    private String mobile;

    @NotNull
    private String address;

    private String zip;

    private String email;


    public Customer(String userId, String mobile, String address, String contactName) {
        this(userId, 1, null, null, mobile, address, null, contactName, null);
    }

    public Customer() {}


    public Customer(Long id, String userId, String mobile, String address, String contactName) {
        this(id, userId, 1, null, null, mobile, address, null, contactName, null);
    }

    public Customer(Long id, String userId, int type, String companyName, String phone, String mobile, String address, String zip, String contactName, String email) {

    public Long getId() {
        return id;
    }


    public String getUserId() {
        return userId;

    public void setUserId(String userId) {
        this.userId = userId;

    public int getType() {
        return type;

    public void setType(int type) {
        this.type = type;

        this.companyName = companyName;

    public String getAddress() {

看起來測試正在使用默認配置，根據Spring Data REST ，該配置將返回204 No Content 參考文檔

5.1.1。 默認狀態碼

對於公開的資源，我們使用一組默認狀態代碼：

• 200 OK-用於簡單的GET請求。

• 201已創建-用於創建新資源的POST和PUT請求。

• 204 No Content-對於PUT，PATCH和DELETE請求，如果配置設置為不返回資源更新的響應主體（RepositoryRestConfiguration.returnBodyOnUpdate）。 如果配置值設置為包括對PUT的響應，則將返回200 OK進行更新，對於通過PUT創建的資源將返回201 Created。

如果配置值（RepositoryRestConfiguration.returnBodyOnUpdate和RepositoryRestConfiguration.returnBodyCreate）明確設置為null，則將使用HTTP Accept標頭來確定響應代碼。
