Spring Boot RestController测试返回404

Question

我试图测试我的RestController代码（Spring Boot项目），但我总是得到404。以下是我目前掌握的情况：

@RestController("/service")
public class ServiceInteractionController {

@Autowired
private PairingService pairingService;

@GetMapping("/registered/{sensorId}")
public ResponseEntity isSensorRegistered(@PathVariable String sensorId) {
    return ResponseEntity.ok(pairingService.isSensorRegistered(sensorId));
}

}

@RunWith(SpringRunner.class)
@WebMvcTest(ServiceInteractionController.class)
public class ServiceInteractionControllerTest {

@Autowired
private MockMvc mockMvc;

@MockBean
private PairingService pairingService;

@Before
public void setUp() {
    Mockito.when(pairingService.isSensorRegistered(TestConstants.TEST_SENSOR_ID))
            .thenReturn(true);
}

@Test
public void testIsSensorRegistered() throws Exception {
    mockMvc.perform(MockMvcRequestBuilders.get("service/registered/{sensorId}", TestConstants.TEST_SENSOR_ID))
            .andExpect(MockMvcResultMatchers.status().isOk());
}

}

结果总是这样：

MockHttpServletRequest:
      HTTP Method = GET
      Request URI = service/registered/test123Id
       Parameters = {}
          Headers = []
             Body = <no character encoding set>
    Session Attrs = {}

Handler:
             Type = null

Async:
    Async started = false
     Async result = null

Resolved Exception:
             Type = null

ModelAndView:
        View name = null
             View = null
            Model = null

FlashMap:
       Attributes = null

MockHttpServletResponse:
           Status = 404
    Error message = null
          Headers = []
     Content type = null
             Body = 
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

java.lang.AssertionError: Status 
Expected :200
Actual   :404

我做错了什么？我已经尝试过直接在setUp方法中用标准设置（）初始化mockmvc，我还使用了@SpringBootTest和@AutoConfigreMockMvc相结合。

有人有什么有用的提示吗？我使用spring boot 2.1.4。

谢谢

Answer 1

尝试将此函数更改为：

@PathVariable 
@Test
public void testIsSensorRegistered(@PathVariable sensorId ) throws Exception {
    mockMvc.perform(MockMvcRequestBuilders.get("service/registered/{sensorId}", TestConstants.TEST_SENSOR_ID))
            .andExpect(MockMvcResultMatchers.status().isOk());
}

Answer 2

您是否错过了服务/registered/{sensorId}之前的“/”键？

mockMvc.perform(MockMvcRequestBuilders.get("service/registered/{sensorId}", TestConstants.TEST_SENSOR_ID))
        .andExpect(MockMvcResultMatchers.status().isOk());
