HttpRequestMethodNotSupportedException：請求方法「POST」不支持

Question

創建具有MockMvc我一個單元測試正在到：

HttpRequestMethodNotSupportedException：請求方法「POST」不支持

導致測試案例失敗的期待「 200'，但得到'405'。您在Junit中可能看到的其他一些內容是Spring Rest Docs，可以忽略。如mockMvc Call上的@Rule或.andDo（）。我遵循以下文檔Spring Rest Docs - Path Parameter，似乎無法讓它工作。

這裏是控制器：

@RestController("/transferObjects") 
public class TransferObjectController { 

    @RequestMapping(method=RequestMethod.GET, produces="application/json") 
    public List<TransferObject> getTransferObjects(){ 
     // do some magic 
     return null; 
    } 

    @RequestMapping(value = "/{name}", method=RequestMethod.POST) 
    @ResponseStatus(HttpStatus.OK) 
    public void addTransferObject(@PathVariable("name")String name){ 
     // do magic 
    } 

    @RequestMapping(value = "/{name}", method=RequestMethod.DELETE) 
    @ResponseStatus(HttpStatus.OK) 
    public void deleteTransferObject(@PathVariable("name")String name){ 
     // do magic 
    } 

這裏是JUnit類：

public class TransferObjectControllerTest { 

@Rule 
public RestDocumentation restDocumentation = new RestDocumentation("target/generated-snippets"); 

private MockMvc mockMvc; 

@Before 
public void setUp() throws Exception {  
    this.mockMvc = MockMvcBuilders.standaloneSetup(new TransferObjectController()) 
      .apply(documentationConfiguration(this.restDocumentation)) 
      .build(); 
} 

@Test 
public void testAddTransferObject() throws Exception { 
    this.mockMvc.perform(post("/transferObjects/{name}", "hi")) 
     .andExpect(status().isOk()).andDo(document("transferObject", 
       pathParameters(
        parameterWithName("name").description("The name of the new Transfer Object to be created.")))); 
} 

這裏是控制檯運行測試時：

Answer 1

看來我能夠解決這個問題。

以在控制檯細看運行我注意到測試而：

Mapped "{[],methods=[GET],produces=[application/json]}" onto public java.util.List<common.to.TransferObject> sf.common.controller.TransferObjectController.getTransferObjects() 
Mapped "{[/{name}],methods=[POST]}" onto public void sf.common.controller.TransferObjectController.addTransferObject(java.lang.String) 
Mapped "{[/{name}],methods=[DELETE]}" onto public void sf.common.controller.TransferObjectController.deleteTransferObject(java.lang.String) 

這表明，它是映射控制器請求映射到特定RequestMapping方法成立。 @RestController("/transferObjects")實際上並未將映射定義爲父項。對於我來說，我必須在@RestController下包含@RequestMapping("/transferObjects")。

因此，通過改變父映射我現在可以使用下面的測試案例：

@Test 
public void testAddTransferObject() throws Exception { 
    this.mockMvc.perform(post("/transferObjects/{name}", "hi")) 
     .andExpect(status().isOk()).andDo(document("transferObject", 
       pathParameters(
        parameterWithName("name").description("The name of the new Transfer Object to be created.")))); 
}
