如何設置OAuth2RestTemplate（Post Updated）

Question

我不確定我是否正確配置了OAuth2RestTemplate。當我運行測試儀類時出現以下錯誤。

類

@Configuration 
public class AppConfig { 

@Bean 
//@Scope(value="singleton", proxyMode=ScopedProxyMode.INTERFACES) 
public BaseOAuth2ProtectedResourceDetails baseOAuth2ProtectedResourceDetails(){ 
    BaseOAuth2ProtectedResourceDetails baseOAuth2ProtectedResourceDetails = new BaseOAuth2ProtectedResourceDetails(); 
    baseOAuth2ProtectedResourceDetails.setClientId(clientId); 
    baseOAuth2ProtectedResourceDetails.setClientSecret(clientSecret); 
    return baseOAuth2ProtectedResourceDetails; 
} 

@Bean 
public DefaultAccessTokenRequest accessTokenRequest(){ 
    return new DefaultAccessTokenRequest(); 
} 

@Bean 
public OAuth2ClientContext oAuth2ClientContext(){ 
    return new DefaultOAuth2ClientContext(accessTokenRequest()); 
} 

@Bean 
public OAuth2RestTemplate oAuth2RestTemplate(){ 
    OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(baseOAuth2ProtectedResourceDetails(),oAuth2ClientContext()); 
    return restTemplate; 
} 
} 

Tester類

public class Tester { 

public static void main(String[] args) { 

    GenericXmlApplicationContext ctx = new GenericXmlApplicationContext(); 
    ctx.load("classpath*:jpa-app-context.xml"); 
    ctx.refresh(); 

EntityManagerFactory emf = (EntityManagerFactory) ctx.getBean("emf"); 
EntityManager em = emf.createEntityManager(); 
TransactionSynchronizationManager.bindResource(emf , new EntityManagerHolder(em)); 
OAuth2RestTemplate oAuth2RestTemplate = (OAuth2RestTemplate) ctx.getBean("oAuth2RestTemplate"); 

//OAuth2RestTemplate oAuth2RestTemplate = ctx.getBean(OAuth2RestTemplate.class); 
String uri="https:api.."; 


Object obj = oAuth2RestTemplate.exchange(uri, HttpMethod.POST, null, Object.class); 
System.out.println("Tester Object: "+ obj.toString()); 
} 
}

我面臨同樣的異常，但與其他受保護的資源類型。

通常，僅當AccessTokenProviderChain找不到適用於特定*ProtectedResourceDetails實例的適當*AccessTokenProvider時，異常纔會引發。這意味着，當您嘗試執行以下操作：

ClientCredentialsResourceDetails resource = new ClientCredentialsResourceDetails(); 

resource.setAccessTokenUri(url); 
resource.setClientId(clientId); 
resource.setClientSecret(secret); 
resource.setGrantType("password"); 

return resource; 

的代碼需要一個client_credentials撥款類型，因爲我們使用ClientCredentialsResourceDetails，但我們傳遞password值。

這裏，在我的情況下工作的代碼：

private OAuth2ProtectedResourceDetails withOAuth2Authentication(final String url, final String clientId, final String secret) { 
    ClientCredentialsResourceDetails resource = new ClientCredentialsResourceDetails(); 

    resource.setAccessTokenUri(url); 
    resource.setClientId(clientId); 
    resource.setClientSecret(secret); 
    // here you can provide additional properties such as scope etc. 

    return resource; 
} 

@Bean 
RestTemplate callbackClientV2() { 
    AccessTokenRequest atr = new DefaultAccessTokenRequest(); 

    return new OAuth2RestTemplate(
       withOAuth2Authentication(v2ServerUrl, v2Username, v2Password), 
       new DefaultOAuth2ClientContext(atr) 
    ); 
}
