没有为接口OAuth2AuthorizedClientService找到主构造函数或单个唯一构造函数
没有为接口OAuth2AuthorizedClientService找到主构造函数或单个唯一构造函数

我试图在一个简单的OAuth2 Spring应用程序中接收访问令牌的字符串形式。这似乎是实现此是与OAuth2AuthorizedClientService的最佳方法。但是，每当尝试使用它时，我都会得到以下错误：
java.lang.IllegalStateException: No primary or single unique constructor found for interface org.springframework.security.oauth2.client.OAuth2AuthorizedClientService

...我的项目再简单不过了，我有一个主类Config和Controller。有两个端点: /home (permitAll)和/test (身份验证)。请求/test时会发生上述错误。
Config (@配置)：
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.mvcMatchers("/test/**").authenticated()
.mvcMatchers("/home/**").permitAll()
// mvcMatchers more secure than antMatchers as it infers other things in path
// regexMatchers allows you to use any regex for matching paths
.and().oauth2Login();
return http.build();
}
private ClientRegistration clientRegistration() {
return CommonOAuth2Provider.GITHUB.getBuilder("github").clientId("<not sharing>")
.clientSecret("<not sharing>")
.scope("user:email").build();
}
@Bean
public ClientRegistrationRepository clientRepository() {
ClientRegistration clientReg = clientRegistration();
return new InMemoryClientRegistrationRepository(clientReg);
}财务主任(@RestController)：
@GetMapping("/home")
public String home() {
return "home page";
}
@GetMapping("/test")
public OAuth2AuthenticationToken testToken(OAuth2AuthenticationToken token,
OAuth2AuthorizedClientService svc) {
var t = svc.loadAuthorizedClient(token.getAuthorizedClientRegistrationId(), token.getName());
System.out.println(t.getAccessToken().getTokenValue());
return token;
}我想我的问题可能是Maven依赖关系。但是，使用上面的文章作为参考，我的依赖关系不应该是一个问题。它们看起来如下：
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>5.7.2</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>5.7.2</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-oauth2-client</artifactId>
<version>2.7.2</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.7.2</version>
</dependency>我用的是jdk-16.0.1。任何帮助都是非常感谢的。

喔，简单的错误。我将OAuth2AuthorizedClientService作为param传递，而不是在控制器中自动连接它。
@Autowired
private OAuth2AuthorizedClientService service;
@GetMapping("/home")
public String home() {
return "home page";
}
@GetMapping("/test")
public OAuth2AuthenticationToken testToken(OAuth2AuthenticationToken token) {
var t = service.loadAuthorizedClient(token.getAuthorizedClientRegistrationId(), token.getName());
System.out.println(t.getAccessToken().getTokenValue());
return token;
}}
