在Spring Boot Thymeleaf控制器返回的视图中显示字符串

Question

我在视图中挣扎，我需要在视图上显示API函数的返回值：

弹簧控制器代码

@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API函数，它返回String 。

我需要在视图index.html上显示它。 非常感谢你。

Answer 1

如下更新您的方法：

@RestController
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;
}

我所做的修改是：用@RestController替换@Controller并更新@RequestMapping

Answer 2

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

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