Question

我正在尝试了解如何使用OAuth2RestTemplate对象来使用我的OAuth2安全REST服务（该服务在不同的项目下运行，我们也假设在不同的服务器上等等）。

f.e。我的休息服务是：

https://localhost:8443/rest/api/user

- ＆GT;访问此URL会生成错误，因为我未经过身份验证

要请求令牌，我会去：

https://localhost:8443/rest/oauth/token?grant_type=password&client_id=test&client_secret=test&username=的 USERNAME ＆安培;密码= 密码

收到令牌后，我可以使用以下URL连接到REST API（插入示例令牌）

https://localhost:8443/rest/api/user?access_token=的 06

我目前尝试使用以下对象：

@EnableOAuth2Client
@Configuration
class MyConfig {

    @Value("${oauth.resource:https://localhost:8443}")
    private String baseUrl;
    @Value("${oauth.authorize:https://localhost:8443/rest/oauth/authorize}")
    private String authorizeUrl;
    @Value("${oauth.token:https://localhost:8443/rest/oauth/token}")
    private String tokenUrl;

    @Bean
    protected OAuth2ProtectedResourceDetails resource() {

        ResourceOwnerPasswordResourceDetails resource = new ResourceOwnerPasswordResourceDetails();

        List scopes = new ArrayList<String>(2);
        scopes.add("write");
        scopes.add("read");
        resource.setAccessTokenUri(tokenUrl);
        resource.setClientId("test");
        resource.setClientSecret("test");
        resource.setGrantType("password");
        resource.setScope(scopes);

        resource.setUsername("test");
        resource.setPassword("test");

        return resource;
    }

    @Bean
    public OAuth2RestOperations restTemplate() {
        CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier())
                .build();
        HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
        requestFactory.setHttpClient(httpClient);
        AccessTokenRequest atr = new DefaultAccessTokenRequest();
        OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(resource(), new DefaultOAuth2ClientContext(atr));
        AuthorizationCodeAccessTokenProvider provider = new AuthorizationCodeAccessTokenProvider();
        provider.setRequestFactory(requestFactory);
        restTemplate.setAccessTokenProvider(provider);
        return restTemplate;
    }

}

我试图在下面的控制器中获取令牌。

@Controller
public class TestController {

    @Autowired
    private OAuth2RestOperations restTemplate;

    @RequestMapping(value="/", method= RequestMethod.GET)
    public String TestForm() {
        System.out.println("Token : " + restTemplate.getAccessToken().getValue());
    }
}

但我得到了以下异常

SEVERE: Servlet.service() for servlet [appServlet] in context with path [/web] threw exception [Request processing failed; nested exception is java.lang.ClassCastException: org.springframework.security.oauth2.client.token.grant.password.ResourceOwnerPasswordResourceDetails cannot be cast to org.springframework.security.oauth2.client.token.grant.code.AuthorizationCodeResourceDetails] with root cause

从一些博客我发现，如果我们需要授予密码，而不是ResourceOwnerPasswordResourceDetails，它应该使用AccessTokenRequest（这是一个Map并且是短暂的）。如果有人可以帮助我获取accessToken，那就太好了。：）

提前致谢！

您应该在ResourceOwnerPasswordAccessTokenProvider bean

中使用AuthorizationCodeAccessTokenProvider代替restTemplate

如何使用OAuth2RestTemplate + Spring 4？
