彈簧測試-mvc框架的彈簧REST控制器測試

這個問題在我問了here的問題旁邊。我正在使用spring-test-mvc框架來測試REST控制器。請參閱上面的鏈接以查看我的REST控制器的代碼。彈簧測試-mvc框架的彈簧REST控制器測試

我的測試GET工作正常，但我不能做POST。當我嘗試這樣做時，我會得到一個例外。這是我第一次測試REST控制器。

這裏是我的PcUserControllerTest類

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = "classpath:/applicationContextTest.xml") 
public class PcUserControllerTest { 

    @Autowired 
    PcUserService pcUserService; 

    @Autowired 
    PcUserController pcUserController; 

    PcUser pcUser; 

    private MockMvc mockMvc; 

    @Before 
    public void setUp() throws Exception { 
     mockMvc = standaloneSetup(pcUserController).build(); 
     pcUser = new PcUser("John", "Li", "Weasley", "john", "john"); 
     pcUserService.create(pcUser); 
    } 

    @After 
    public void tearDown() throws Exception { 
     pcUserService.delete(pcUser.getId()); 
    } 

    @Test 
    public void shouldGetPcUser() throws Exception { 
     this.mockMvc.perform(get("/pcusers/" + pcUser.getId()).accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk()); 
    } 

    @Test 
    public void shouldCreatePcUser() throws Exception { 
     PcUser newUser = new PcUser("Mike", "Li", "Donald", "mike", "mike"); 
     this.mockMvc.perform(post("/pcusers/create/" + newUser).accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk()); 
    } 
}

例外，我得到當我執行shouldCreatePcUser：

我PcUser看起來像

@Document 
public class PcUser extends BaseEntity { 
    private String firstName; 
    private String middleName; 
    private String lastName; 
    private String username; 
    private String password; 

    public PcUser() { 
     super(); 
    } 

    public PcUser(String firstName, String middleName, String lastName, 
      String username, String password) { 
     super(); 
     this.firstName = firstName; 
     this.middleName = middleName; 
     this.lastName = lastName; 
     this.username = username; 
     this.password = password; 
    } 

    public String getFirstName() { 
     return firstName; 
    } 

    public void setFirstName(String firstName) { 
     this.firstName = firstName; 
    } 

    public String getMiddleName() { 
     return middleName; 
    } 

    public void setMiddleName(String middleName) { 
     this.middleName = middleName; 
    } 

    public String getLastName() { 
     return lastName; 
    } 

    public void setLastName(String lastName) { 
     this.lastName = lastName; 
    } 

    public String getUsername() { 
     return username; 
    } 

    public void setUsername(String username) { 
     this.username = username; 
    } 

    public String getPassword() { 
     return password; 
    } 

    public void setPassword(String password) { 
     this.password = password; 
    } 

    @Override 
    public String toString() { 
//  JSONObject jsonPcUser = new JSONObject(); 
//  jsonPcUser.put("id", this.getId()); 
//  jsonPcUser.put("firstName", this.firstName); 
//  jsonPcUser.put("middleName", this.middleName); 
//  jsonPcUser.put("lastName", this.lastName); 
//  jsonPcUser.put("username", this.username); 
// 
//  return jsonPcUser.toJSONString(); 

     return "{\"firstName\":" + this.firstName + ", " 
       + "\"middleName\":" + this.middleName + ", " 
       + "\"lastName\":" + this.lastName + ", " 
       + "\"username\":" + this.username 
       + "}"; 
    } 
}

BaseEntity：

public class BaseEntity { 
    @Id 
    private String id; 

    public BaseEntity() { 
    } 

    public String getId() { 
     return id; 
    } 

    public void setId(String id) { 
     this.id = id; 
    } 
}

我不明白這個例外。如果任何人能夠指引我在正確的方向將非常感激。

好吧，你有這個作爲你的get：

get("/pcusers/" + pcUser.getId())

，因爲你想在/pcusers/123/獲取資源這是合理的，但你必須：

PcUser newUser = new PcUser("Mike", "Li", "Donald", "mike", "mike"); 
post("/pcusers/create/" + newUser)

不真的很有意義，因爲您將在newUser對象上執行toString()，然後將其與/pcusers/create/字符串連接起來。所以你可能正在做一個像/pcusers/create/[email protected]這樣的請求，這可能不是你想要的。

是的，你說得對，toString（）方法會被調用。我重寫了toString（）方法，它以JSON格式返回數據。這個想法是這樣做的：/ pcusers/create/{firstName：Mike，middleName：Li，lastName：Rubble}，當它到達服務器時，它將被轉換成一個PcUser對象。正如我所說這是我第一次玩REST控制器，這是不正確的。我們應該如何在POST中傳遞數據？ – jsf 2012-02-06 14:14:01

當然，你在POST中傳遞數據，但不是那樣。它需要位於POST的** body **中，而不是url的一部分。 – beerbajay 2012-02-06 14:33:21

是的，這解決了我的問題並解決了這個問題。非常感謝你的幫助。非常感謝。 – jsf 2012-02-06 17:34:55

看起來，正如beerbajay提到的那樣，問題是您要發佈到控制器的是PcUser作爲URL /路徑參數，而不是HTTP請求的實際主體。

我使用org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder＃含量（字符串）方法來設置HTTP請求本身的主體（而不是替代URL的部分或添加URL參數）如下：

PcUser newUser = new PcUser("Mike", "Li", "Donald", "mike", "mike"); 
this.mockMvc.perform(post("/pcusers/create/") 
      .content(newUser.toString()) // <-- sets the request content ! 
      .accept(MediaType.APPLICATION_JSON) 
      .andExpect(status().isOk());
