我已经创建了一个 RESTful 网络服务来对工作流执行操作。 Web 服务使用我自己的授权服务器通过 oauth2 进行保护。 我想在我的工作流程中添加有关谁对其执行操作的信息。我想不通的是，谁可以获取调用 Web 服务的用户名。

对于 Web 服务实现，我使用 jersey (1.18.1)，为了安全，我使用 spring-security-oauth2 (2.0.2.RELEASE)。

我正在使用数据库 token 存储，其中包含一个表 OAUTH_ACCESS_TOKEN(TOKEN_ID、TOKEN、AUTHENTICATION_ID、USER_NAME、CLIENT_ID、AUTHENTICATION、REFRESH_TOKEN)，看起来包含正确的信息。它有用户名和 token ，但 token 看起来像一个序列化的 java 对象，所以我无法自己查询它。

网络服务:

@Component
@Path("/workflows")
public class WorkflowRestService {

    @POST
    @Path("/{id}/actions")
    @Produces(MediaType.APPLICATION_JSON)
    @Transactional
    public Response executeActions(@PathParam("id") String id, Map<String, Object> actionArgs) throws JAXBException, HealthDataException {

        //would like to have/get username here.

        Workflow workflow = workflowService.get(id);
        Action action = actionFactory.getAction(actionArgs);
        workflow.execute(action);
        Workflow update = workflowService.update(workflow);
        return Response.ok(update).build();
    }
}

网络服务安全配置:

最佳答案

由于您使用 Spring Security 进行身份验证，我希望您可以访问 SecurityContext(通过通常的线程本地访问器):

Authentication authentication = SecurityContextHolder.getContext()
    .getAuthentication();

或通过HttpServletRequest:

Principal principal = request.getUserPrincipal();

(或者如果您使用的是 Spring MVC，则只需将 Principal 添加为 @Controller 中的方法参数)。在任何一种情况下，由于您在 Spring OAuth 过滤器后面，您还应该发现 Principal/Authentication 是 OAuth2Authentication 的实例，用户详细信息以及客户端在那里。
