После добавления swagger lib, весь тип содержимого ответа изменен на приложение/xml

Question

Я новичок для чванства и весны MVC. На прошлой неделе я просто попытался интегрировать swagger в нашу систему. Все кажется здоровым до тех пор, пока я не развожу новую войну. Я обнаружил, что все ответы автоматически изменены в формате xml ... Может ли кто-нибудь дать какое-то направление о том, где я должен исследовать? Я пробовал следующие вещи: 1. Вернуть конфигурацию пружины исключить, не работать. 2. add configureContentNegotiation configurer.defaultContentType (MediaType.APPLICATION_JSON), не работает. Любые предложения приветствуются! Спасибо!

Мой файл пружинный конфигурации:

Один мой контроллер:

@Api(value = "students", description = "Student API") 
@RequestMapping("/api/v1/students") 
public class StudentController { 
@Autowired 
private CommonService commonService; 
@Autowired 
private StudentService studentService; 

@ResponseBody 
@RequestMapping(value="/{studentId}/scores/statistics",method = RequestMethod.GET) 
    public ScoreStatisticsViewModel getScoreStatistics(@PathVariable String studentId,@RequestParam String startDate,@RequestParam String endDate){ 
     return commonService.getScoreStatisticsViewModel(studentId,startDate,endDate,null,null,null,null); 
    } 
}

Answer 1

Он должен работать, если вы явно задано eac h контроллер для «производства» JSON. Я уверен, что есть способ сделать это и в конфиге, но я всегда думал, что было бы лучше всего настроить производство и потребление явно.

@RequestMapping(value="/{studentId}/scores/statistics", 
      produces = {"application/json"}, 
      consumes = {"application/json"}, 
      method = RequestMethod.GET)
