如何使用Spring Social通过Facebook注册

Question

我是Spring Social的新手。我正在研究Java Spring社交应用，我希望能够通过Facebook注册。谁能以例子来做出回应？

在弹簧控制器回调方法

中

@RequestMapping(value = "/callback", method = RequestMethod.GET)
    @ResponseBody
    public String postOnWall(@RequestParam("code") String code,
            @RequestParam("state") String state, HttpServletRequest request,
            HttpServletResponse response) throws Exception {
        System.out.println("hi welcome to callback method");
        OAuthService oAuthService = facebookServiceProvider.getService();
        Verifier verifier = new Verifier(code);
        Token accessToken = oAuthService
                .getAccessToken(Token.empty(), verifier);
//      Token accessToken = new Token("EAADOe1JXBWgBAJVtLpGKTM6pol0n8r8fZAHnEPmNZCnId9419k9EHj2scdtcZBotMW5oYneKTvY93ZASRpeUGLiXRKhWvuZBA3zfEgIjGpvLMZCzODvA3SuNm9glARg0c5puZARVuTyZAiSqibD76taIUk06O08lOSm2vJDufCAlUdIP8P9c4ZBLP", "", "");
        System.out.println("accessToken "+accessToken);
        FacebookTemplate template = new FacebookTemplate(accessToken.getToken());
        System.out.println(template.isAuthorized()+" autherized or not condition");
        FacebookProfile facebookProfile = template.userOperations()
                .getUserProfile();
        System.out.println("user permissions "+template.userOperations().getUserPermissions());
        String userId = facebookProfile.getId();
        System.out.println("user about "+facebookProfile.getAbout());
        LOGGER.info("Logged in User Id : {}", userId);
        MultiValueMap<String, Object> map = facebookUtil
                .publishLinkWithVisiblityRestriction(state);
        try {
            template.publish(facebookProfile.getId(), "feed", map);
        } catch (Exception ex) {
            LOGGER.error(
                    "Exception Occurred while posting a link on facebook for user Id : {}, exception is : {}",
                    userId, ex);
            return PUBLISH_ERROR;
        }
        return PUBLISH_SUCCESS;
    }

在上面的方法中，我将所有参数（例如电子邮件，名字等）作为null
