我遇到了一個問題，我得到了三個對象而不是一個對象本身。（您可以在下面看到我的架構和輸出結果）。我需要做的就是返回一個對象映射器列表，它可以將集合轉換為數組。在我的控制器中，這是“public @ResponseBody List”的原因，請幫助我讓它像我的模式一樣打印。感謝您的幫助..！控制器：@RestControllerpublic class AutoCompleteController {    private AutoCompleteService autoCompleteService;    private EntityManager em;    public AutoCompleteController(AutoCompleteService autoCompleteService, EntityManager em){        this.autoCompleteService = autoCompleteService;        this.em = em;    }    @RequestMapping(value = "jobs", method = RequestMethod.GET)    public @ResponseBody List<AutoComplete> getSalary(@RequestParam(value = "autocomplete") String autocompleteValue) {      return autoCompleteService.retrieveSalary(autocompleteValue);    }    public void getAllSalaries(HttpServletResponse res) {        Stream<AutoComplete> stream = autoCompleteService.retrieveAllSalaries();        DataStreamUtility.streamObjects(stream, res, em);    }    @RequestMapping(value = "/jobs")    public @ResponseBody List < AutoComplete > getSalary(@RequestParam(value = "autocomplete", defaultValue = "1400") String autocompleteValue) {        return autoCompleteService.retrieveSalary(autocompleteValue);     }    public void getAllSalaries(HttpServletResponse res) {      Stream < AutoComplete > stream = autoCompleteService.retrieveAllSalaries();      DataStreamUtility.streamObjects(stream, res, em);    }}
