java MockMvc返回404

Question

我编写了控制器，它为每个映射使用不同的值。现在我对它进行折射，以便对所有映射使用相同的值，但是我不知道如何使测试工作，因为它对每个映射返回404

这是我的控制器：

@CrossOrigin(origins = "*")
@RestController
@RequestMapping("/v1")
public class TaskController {

    @Autowired
    DbService dbService;
    @Autowired
    TaskMapper taskMapper;

    @GetMapping(value = "/tasks")
    public List<TaskDto> getTasks() {
        return taskMapper.mapToTaskDtoList(dbService.getAllTask());
    }

    @GetMapping(value = "/tasks/{id}")
    public TaskDto getTask(@PathVariable Long id) throws TaskNotFoundException {
        return taskMapper.mapToTaskDto(dbService.getTask(id).orElseThrow(TaskNotFoundException::new));
    }

    @DeleteMapping(value = "/tasks/{id}")
    public void deleteTask(@PathVariable Long id) {
        dbService.deleteTask(id);
    }

    @PutMapping(value = "/tasks")
    public TaskDto updateTask(@RequestBody TaskDto taskDto) {
        return taskMapper.mapToTaskDto(dbService.saveTask(taskMapper.mapToTask(taskDto)));
    }

    @PostMapping(value = "/tasks", consumes = APPLICATION_JSON_VALUE)
    public void createTask(@RequestBody TaskDto taskDto) {
        dbService.saveTask(taskMapper.mapToTask(taskDto));
    }
}

还有我的测试：

@RunWith(SpringRunner.class)
@WebMvcTest(TaskController.class)
public class TaskControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @MockBean
    private DbService dbService;

    @MockBean
    private TaskMapper taskMapper;

    @Test
    public void shouldFetchAllTasks() throws Exception {
        //Given
        List<TaskDto> tasks = new ArrayList<>();
        tasks.add(new TaskDto(1L, "test", "testing"));
        tasks.add(new TaskDto(2L, "test2", "still_testing"));

        when(taskMapper.mapToTaskDtoList(dbService.getAllTask())).thenReturn(tasks);
        //When & Then
        mockMvc.perform(get("/v1/task/tasks").contentType(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$", hasSize(2)))
                .andExpect(jsonPath("$[0].id", is(1)))
                .andExpect(jsonPath("$[0].title", is("test")))
                .andExpect(jsonPath("$[0].content", is("testing")))
                .andExpect(jsonPath("$[1].id", is(2)))
                .andExpect(jsonPath("$[1].title", is("test2")))
                .andExpect(jsonPath("$[1].content", is("still_testing")));
    }

    @Test
    public void shouldFetchGivenTask() throws Exception {
        //Given
        List<TaskDto> tasks = new ArrayList<>();
        tasks.add(new TaskDto(1L, "test", "testing"));
        tasks.add(new TaskDto(2L, "test2", "still_testing"));

        when(dbService.getTask(anyLong())).thenReturn(Optional.of(new Task(2L, "test2", "still_testing")));
        when(taskMapper.mapToTaskDto(anyObject())).thenReturn(tasks.get(1));
        //When & Then
        mockMvc.perform(get("/v1/task/tasks/{id}", "2")
                .contentType(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.id", is(2)))
                .andExpect(jsonPath("$.title", is("test2")))
                .andExpect(jsonPath("$.content", is("still_testing")));
    }

    @Test
    public void shouldUpdateTask() throws Exception {
        //Given
        TaskDto taskDto = new TaskDto(1L, "test", "testing");
        TaskDto updatedTaskDto = new TaskDto(1L, "updated task", "even more testing");

        when(taskMapper.mapToTaskDto(dbService.saveTask(taskMapper.mapToTask(taskDto)))).thenReturn(updatedTaskDto);

        Gson gson = new Gson();
        String jsonContent = gson.toJson(taskDto);

        //When & Then
        mockMvc.perform(put("/v1/task/tasks")
                .contentType(MediaType.APPLICATION_JSON)
                .content(jsonContent))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.id", is(1)))
                .andExpect(jsonPath("$.title", is("updated task")))
                .andExpect(jsonPath("$.content", is("even more testing")));
    }

    @Test
    public void shouldDeleteTask() throws Exception {
        //Given
        //When & Then
        mockMvc.perform(delete("/v1/task/tasks/{id}","1"))
                .andExpect(status().isOk());
    }

    @Test
    public void shouldCreateTask() throws Exception {
        //Given
        //When & Then
        mockMvc.perform(post("/v1/task/tasks")
                .contentType(MediaType.APPLICATION_JSON)
                .content("{\"title\":\"another test\"," +
                        "\"content\":\"keep on testing\"}"))
                .andExpect(status().isOk());
    }
}

url-/v1/task/tasks不存在于控制器中的任何请求映射中。您的类级控制器具有/v1请求映射，而您的方法级请求映射具有/tasks而非/task，因此您将得到404未找到错误
