我正在将 google 注册/登录添加到我的网络应用程序，但遇到了问题。

这是我的代码：

private static final HttpTransport transport = new NetHttpTransport();
private static final JsonFactory jsonFactory = new JacksonFactory();
private static final String MY_APP_GOOGLE_CLIENT_ID = "wouldntyouliketoknow";

public UsernamePasswordAuthenticationToken verify(final String idTokenString){

    GoogleIdTokenVerifier verifier = new GoogleIdTokenVerifier.Builder(transport, jsonFactory)
                                            .setAudience(Collections.singletonList(MY_APP_GOOGLE_CLIENT_ID))
                                            .build();

    try {
        GoogleIdToken idToken = verifier.verify(idTokenString);// <-- verifier.verify returns null !!!
        if (idToken != null) {
            Payload payload = idToken.getPayload();
            String email = payload.getEmail();
            if(Boolean.valueOf(payload.getEmailVerified())){
                UserJPA jpa = userRepository.findByEmail(email);
                if(jpa==null){
                    throw new UsernameNotFoundException("Cannot find user with email = "+email);
                } …

我正在制作一个Spring Boot REST应用程序。我正在尝试制作一个多部分表单上载控制器，它将一起处理表单数据和文件上载。这是我目前的控制器代码：

    @RequestMapping(value = "", method = RequestMethod.POST, headers="Content-Type=multipart/form-data")
    @PreAuthorize("hasRole('ROLE_MODERATOR')")
    @ResponseStatus(HttpStatus.CREATED)
    public void createNewObjectWithImage(
            /*@RequestParam(value="file", required=true) MultipartFile file,
            @RequestParam(value="param_name_1", required=true) final String param_name_1,
            @RequestParam(value="param_name_2", required=true) final String param_name_2,
            @RequestParam(value="param_name_3", required=true) final String param_name_3,
            @RequestParam(value="param_name_4", required=true) final String param_name_4,
            @RequestParam(value="param_name_5", required=true) final String param_name_5*/
            @ModelAttribute ModelDTO model,
            BindingResult result) throws MyRestPreconditionsException {

        //ModelDTO model = new ModelDTO(param_name_1, param_name_2, param_name_3, param_name_4, param_name_5);

        modelValidator.validate(model, result);
        if(result.hasErrors()){
            MyRestPreconditionsException ex = new MyRestPreconditionsException(
                    "Model creation error",
                    "Some of the elements in the request are …
