java - 我如何通过junits中的参数传递一个类？

Question

我有一个 API :

@RequestMapping(value = "/area/create",
                method = RequestMethod.POST,
                produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public ResponseEntity<AreaEntry> createNewAreaEntry(
            @RequestBody AreaRequestDto areaRequestDto) throws ServiceException {
    UserContextHolder.setCustomer(areaRequestDto.getAreaEntry().getHost());
    UserContextHolder.setSsoId(areaRequestDto.getUser());
    AreaEntry newAreaEntryDto = service.createNewAreaEntry(areaRequestDto.getAreaEntry());
    System.out.println("The area entries" + areaRequestDto.getUser()
                       + "  " + " " 
                       + areaRequestDto.getAreaEntry().getName() 
                       + "  " 
                       + areaRequestDto.getAreaEntry().getCode() + " deugging");
    System.out.println("the new area entry dto is" + newAreaEntryDto);
    return new ResponseEntity<AreaEntry>(newAreaEntryDto, HttpStatus.OK);

我需要编写一个 JUnit:

private List<String> getInvalidAreas(String areas) throws Exception {
    ResultActions actions = mockMvc.perform(get("/area/create").param("cities", areas));
}

我需要在参数中传递类arerequest dto我该怎么做？

你可以简单地传递json字符串，它会自动反序列化并转换为DTO。或者您可以创建实用程序方法，将 dto 对象转换为 json 并将其作为请求正文传递。

 public String asJsonString(final Object obj) throws JsonProcessingException {
        final ObjectMapper mapper = new ObjectMapper();
        mapper.registerModule(new JavaTimeModule());
        mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
        return mapper.writeValueAsString(obj);
    }
