java在Spring Boot EleAF控制器返回的视图中显示字符串

Question

我正在视图中挣扎，我需要在视图上显示API函数的返回：

Spring Controller Code

@Controller
public class mainController {

  @RequestMapping(value = {"/"}, method = RequestMethod.GET)
  public String index() throws IOException, GeneralSecurityException {
    DriveQuickstart drive = new DriveQuickstart("c:/temp/credentials.json");
    String res = drive.checkFile("cwg");

    return res;

drive.checkFile是一个返回String的API函数

我需要在我的视图上显示它。 非常感谢你，穆奇

Answer 1

@GetMapping("/")
public String index(Model model) throws IOException, GeneralSecurityException {
        DriveQuickstart drive = new DriveQuickstart("c:/temp/credentials.json");
        model.addAttribute("drive", drive)
    return "/routeToTemplate";
    }

在特里梅莱夫

<div th:text="${drive}"></div>
