如何解决如何解决此问题：LoginController 中构造函数的参数 0 需要一个无法找到的“OktaOAuth2Properties”类型的 bean

我已按照 tutorial 使用 Java 11 向 Spring Boot 应用程序添加社交登录。我遇到的问题是：

***************************
APPLICATION Failed TO START
***************************

Description:

Parameter 0 of constructor in com.okta.spring.example.controllers.LoginController required a bean of type 'com.okta.spring.boot.oauth.config.OktaOAuth2Properties' that Could not be found.


Action:

Consider defining a bean of type 'com.okta.spring.boot.oauth.config.OktaOAuth2Properties' in your configuration.

项目结构是：

LoginController 就像：

@Controller
public class LoginController {

    private static final String STATE = "state";
    private static final String NONCE = "nonce";
    private static final String ScopES = "scopes";
    private static final String OKTA_BASE_URL = "oktaBaseUrl";
    private static final String OKTA_CLIENT_ID = "oktaClientId";
    private static final String REDIRECT_URI = "redirectUri";
    private static final String ISSUER_URI = "issuerUri";

    private final OktaOAuth2Properties oktaOAuth2Properties;

    public LoginController(OktaOAuth2Properties oktaOAuth2Properties) {
        this.oktaOAuth2Properties = oktaOAuth2Properties;
    }

    @GetMapping(value = "/signin")
    public ModelAndView login(HttpServletRequest request,@RequestParam(name = "state",required = false) String state,@RequestParam(name = "nonce") String nonce) throws MalformedURLException {

        // if we don't have the state parameter redirect
        if (state == null) {
            return new ModelAndView("redirect:" + oktaOAuth2Properties.getRedirectUri());
        }

        String issuer = oktaOAuth2Properties.getIssuer();
        // the widget needs the base url,just grab the root of the issuer
        String orgUrl = new URL(new URL(issuer),"/").toString();

        ModelAndView mav = new ModelAndView("login");
        mav.addobject(STATE,state);
        mav.addobject(NONCE,nonce);
        mav.addobject(ScopES,oktaOAuth2Properties.getScopes());
        mav.addobject(OKTA_BASE_URL,orgUrl);
        mav.addobject(OKTA_CLIENT_ID,oktaOAuth2Properties.getClientId());
        // from ClientRegistration.redirectUriTemplate,if the template is change you must update this
        mav.addobject(REDIRECT_URI,request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() +
            request.getcontextpath() + "/authorization-code/callback"
        );
        mav.addobject(ISSUER_URI,issuer);

        return mav;
    }

    @GetMapping("/post-logout")
    public String logout() {
        return "logout";
    }

    @GetMapping("/403")
    public String error403() {
        return "403";
    }
}

问题是如果所有文件都按照每个步骤进行配置，如何修复它。

我检查了以下不同的答案：

但他们都没有帮助我。

解决方法

问题出在文件命名上。当我更改 yml 的名称时：

application.yml 而不是 application.template.yml

问题消失了。
