我在測試中反序列化時遇到問題。我有簡單的返回一些對象。當我調用我的端點時，響應沒有問題 - 它是正確的。然后我嘗試編寫單元測試，獲取并使用它轉換為我的對象。但我仍然收到：LocalDateTimeJunitREST APIDTOMvcResultObjectMapperDTOcom.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.time.LocalDateTime` out of START_ARRAY token at [Source: (String)"{"name":"Test name","firstDate":[2019,3,11,18,34,43,52217600],"secondDate":[2019,3,11,19,34,43,54219000]}"; line: 1, column: 33] (through reference chain: com.mylocaldatetimeexample.MyDto["firstDate"])我正在嘗試并添加到我的，但我使用所以它參與其中。我不知道如何解決它。我下面的簡單端點和單元測試：@JsonFormatcompile group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jsr310', version: '2.9.8'build.gradleSpring Boot 2.1.3.RELEASE@RestController@RequestMapping("/api/myexample")public class MyController {    @GetMapping("{id}")    public ResponseEntity<MyDto> findById(@PathVariable Long id) {        MyDto myDto = new MyDto("Test name", LocalDateTime.now(), LocalDateTime.now().plusHours(1));        return ResponseEntity.ok(myDto);    }}我的課程public class MyDto {    private String name;    private LocalDateTime firstDate;    private LocalDateTime secondDate;// constructors, getters, setters}單元測試public class MyControllerTest {    @Test    public void getMethod() throws Exception {        MyController controller = new MyController();        MockMvc mockMvc = MockMvcBuilders.standaloneSetup(controller).build();        MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/api/myexample/1"))                .andExpect(MockMvcResultMatchers.status().isOk()).andReturn();        String json = mvcResult.getResponse().getContentAsString();        MyDto dto = new ObjectMapper().readValue(json, MyDto.class);        assertEquals("name", dto.getName());    }}
