Java OAuth2Client每次都返回相同的令牌

我有授权服务器。除了标准的功能外，我还有一个控制器，它允许创建用户。用户创建成功后，该方法必须返回此用户的令牌。问题是该方法仅在第一次调用时返回有效令牌。在下一次调用中，以下用户将获得第一个用户的令牌。我试图为restTemplate设置作用域（请求），但得到了错误：“作用域‘请求’对于当前线程不是活动的”

和我的控制器：

@RestController
public class UserRestController {
    @Autowired
    private OAuth2RestOperations restTemplate;

    @PostMapping("/user")
    public OAuth2AccessToken createUserCredential(@RequestBody UserCredential user) {
        user.validate();
        userCredentialService.checkAndSaveUser(user, getClientIp(request));

        restTemplate.getOAuth2ClientContext().getAccessTokenRequest().set("username", user.getLogin());
        restTemplate.getOAuth2ClientContext().getAccessTokenRequest().set("password", user.getPassword);
        return restTemplate.getAccessToken();
    }
}

@RestController
public class UserRestController {

    @Autowired
    private OAuthClientConfig oAuthClientConfig;

    @PostMapping("/user")
    public OAuth2AccessToken createUserCredential(@RequestBody UserCredential user) {
        user.validate();
        userCredentialService.checkAndSaveUser(user, getClientIp(request));

        OAuth2RestOperations restTemplate = oAuthClientConfig.restTemplate();
        restTemplate.getOAuth2ClientContext().getAccessTokenRequest().set("username", user.getLogin());
        restTemplate.getOAuth2ClientContext().getAccessTokenRequest().set("password", user.getPassword);
        return restTemplate.getAccessToken();
    }
}

在AuthorizationServer内部可能存在更正确的获取令牌的方法吗？

我认为有一些特殊的方法。。但是没有找到它。并按以下方法解决了问题

 @EnableOAuth2Client
@Configuration
public class OAuthClientConfig {

    @Autowired
    AuthorizationServerConfig authorizationServerConfig;

    public OAuth2RestOperations restTemplate() {
        AccessTokenRequest atr = new DefaultAccessTokenRequest();

        return new OAuth2RestTemplate(authorizationServerConfig.getOwnerPasswordResource(), new DefaultOAuth2ClientContext(atr));
    }
}

和我的控制器：

@RestController
public class UserRestController {
    @Autowired
    private OAuth2RestOperations restTemplate;

    @PostMapping("/user")
    public OAuth2AccessToken createUserCredential(@RequestBody UserCredential user) {
        user.validate();
        userCredentialService.checkAndSaveUser(user, getClientIp(request));

        restTemplate.getOAuth2ClientContext().getAccessTokenRequest().set("username", user.getLogin());
        restTemplate.getOAuth2ClientContext().getAccessTokenRequest().set("password", user.getPassword);
        return restTemplate.getAccessToken();
    }
}

@RestController
public class UserRestController {

    @Autowired
    private OAuthClientConfig oAuthClientConfig;

    @PostMapping("/user")
    public OAuth2AccessToken createUserCredential(@RequestBody UserCredential user) {
        user.validate();
        userCredentialService.checkAndSaveUser(user, getClientIp(request));

        OAuth2RestOperations restTemplate = oAuthClientConfig.restTemplate();
        restTemplate.getOAuth2ClientContext().getAccessTokenRequest().set("username", user.getLogin());
        restTemplate.getOAuth2ClientContext().getAccessTokenRequest().set("password", user.getPassword);
        return restTemplate.getAccessToken();
    }
}

也许这会对某人有所帮助

我面临着同样的问题，我找到了另一种方法使它发挥作用

@Bean
@Primary
@Scope(value = WebApplicationContext.SCOPE_REQUEST, proxyMode = ScopedProxyMode.TARGET_CLASS)
public OAuth2RestTemplate oauth2RestTemplate(OAuth2ClientContext context,
            OAuth2ProtectedResourceDetails details) {

        AccessTokenRequest atr = new DefaultAccessTokenRequest();
        OAuth2RestTemplate template = new OAuth2RestTemplate(resource(), new DefaultOAuth2ClientContext(atr));
        AccessTokenProvider accessTokenProvider = new AccessTokenProviderChain(Arrays.<AccessTokenProvider>asList(
                new AuthorizationCodeAccessTokenProvider(), new ImplicitAccessTokenProvider(),
                new ResourceOwnerPasswordAccessTokenProvider(), new ClientCredentialsAccessTokenProvider()));
        template.setAccessTokenProvider(accessTokenProvider);
        return template;

    }

private final OAuth2RestTemplate oauth2RestTemplate;
    @GetMapping(path = "/token")
    public String token(Credentials  credentials) {
    oauth2RestTemplate.getOAuth2ClientContext()
             .getAccessTokenRequest().add("username", credentials.getEmail());
    oauth2RestTemplate.getOAuth2ClientContext()
             .getAccessTokenRequest().add("password", credentials.getPass());
    final OAuth2AccessToken accessToken = oauth2RestTemplate.getAccessToken();
    final String accessTokenAsString = accessToken.getValue();
    return accessTokenAsString ;
    }
