Question

我有一个带有后处理程序的restcontroller，如下所示。

class Master_programmer:
    STATIC_VARIABLE_ONE_FOR_EVERY_INSTANCES = 'This is Static Var'
    def __init__(self, name):
        self.name = name
        self.capabilities = []
        self.student = "SoloLearn Student"
        self.programmer = "Programmer"

    def get_student(self): 
        return self.student

    def get_programmer(self): 
        return self.programmer

    def add_capabilities(self, capability):
        self.capabilities.append(capability)

# Create instance for your class and name it coder (or whatever you like)
coder = Master_programmer('Replace me with student name')

# to call coder object's variable 
# you need to call it by object name just like below
print('capabilities: ', coder.capabilities)
print(coder.programmer)
print(coder.student)
coder.add_capabilities('Stay Inspired')
coder.add_capabilities('Find Clients')
print(coder.get_student())
print(coder.get_programmer())
print('capabilities: ', coder.capabilities)
print()

# you can invoke Static variables usign directly class name
# you can invoke usign instance name as well but, it is not convention
print(Master_programmer.STATIC_VARIABLE_ONE_FOR_EVERY_INSTANCES)
print()

# if you change Static member, it will get change for all of your instances
coder_2 = Master_programmer('Replace me with student name')
Master_programmer.STATIC_VARIABLE_ONE_FOR_EVERY_INSTANCES = 'changed'
print()

# print static var using both ways
print(Master_programmer.STATIC_VARIABLE_ONE_FOR_EVERY_INSTANCES)
print(coder.STATIC_VARIABLE_ONE_FOR_EVERY_INSTANCES)
print(coder_2.STATIC_VARIABLE_ONE_FOR_EVERY_INSTANCES)

现在，我正在尝试为此控制器编写一个单元测试（请参见下面的代码），但是当我执行该测试文件时，我得到一个“ HttpMessageNotReadableException”。但是，当我使用邮递员发送POST请求时，它就可以正常工作。

@RestController
public class TrajectoryController {
    private TrajectoryService trajectoryService;

    TrajectoryController(TrajectoryService trajectoryService) { this.trajectoryService = trajectoryService; }

    @PostMapping(
            path = "api/trajectory",
            consumes = MediaType.APPLICATION_JSON_VALUE,
            produces = MediaType.APPLICATION_JSON_UTF8_VALUE
    )
    public void createTrajectory(@RequestBody Trajectory t) { trajectoryService.createTrajectory(t); }

我已经查找过它，并且以为自己发布了错误的请求正文，但是正如在控制器中看到的那样，“ createTrajectory”方法请求的是Trajectory类的对象。我想知道如何解决此问题？您可以在下面找到输出。

@ActiveProfiles("test")
@SpringBootTest
@AutoConfigureMockMvc
@TestMethodOrder(OrderAnnotation.class)
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
class TrajectoryControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Autowired
    private ObjectMapper mapper;

    @Autowired
    TrajectoryRepository repository;

    private Trajectory trajectory;

    @BeforeAll
    void clean(){
        repository.deleteAll();
    }

    @Test
    @Order(1)
    void createTrajectory() throws Exception {
        this.trajectory = new Trajectory("MyTrajectory1","MT1");
        this.trajectory.setId(1);

        MvcResult result = mockMvc.perform(post("/api/trajectory")
                .contentType(MediaType.APPLICATION_JSON).content(mapper.writeValueAsString(trajectory)))
                .andExpect(status().isCreated())
                .andExpect(jsonPath("$.name", is(trajectory.getName())))
                .andReturn();
        this.trajectory = mapper.readValue(result.getResponse().getContentAsString(), Trajectory.class);

        assertNotNull(this.trajectory.getId());
    }

单元测试时尝试将发布请求发送到REST控制器时出现HttpMessageNotReadableException
