Spring OAuth2-在令牌存储中手动创建访问令牌

Question

我遇到一种情况，我想自己创建一个访问令牌（因此不能通过通常的过程）。我想出了这样的东西：

@Inject
private DefaultTokenServices defaultTokenServices;

...

OAuth2Authentication auth = xxx;
OAuth2AccessToken  token = defaultTokenServices.createAccessToken(auth);

唯一的问题是我不确定如何创建OAuth2Authentication（在我的代码中带有xxx的部分）。我有用户和客户信息，我知道我想授予该令牌的单位。

在这里，根据使用的流程，您的用例可能会略有不同。这适用于密码授予流程。有一些自定义类，如令牌存储，令牌增强器等。但这实际上只是为满足我们自己的需要而修改的spring类的扩展版本。

        HashMap<String, String> authorizationParameters = new HashMap<String, String>();
        authorizationParameters.put("scope", "read");
        authorizationParameters.put("username", "mobile_client");
        authorizationParameters.put("client_id", "mobile-client");
        authorizationParameters.put("grant", "password");

        DefaultAuthorizationRequest authorizationRequest = new DefaultAuthorizationRequest(authorizationParameters);
        authorizationRequest.setApproved(true);

        Set<GrantedAuthority> authorities = new HashSet<GrantedAuthority>();
        authorities.add(new SimpleGrantedAuthority("ROLE_UNTRUSTED_CLIENT"));
        authorizationRequest.setAuthorities(authorities);

        HashSet<String> resourceIds = new HashSet<String>();
        resourceIds.add("mobile-public");
        authorizationRequest.setResourceIds(resourceIds);

        // Create principal and auth token
        User userPrincipal = new User(user.getUserID(), "", true, true, true, true, authorities);

        UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(userPrincipal, null, authorities) ;

        OAuth2Authentication authenticationRequest = new OAuth2Authentication(authorizationRequest, authenticationToken);
        authenticationRequest.setAuthenticated(true);

        CustomTokenStore tokenStore = new CustomTokenStore();

        // Token Enhancer
        CustomTokenEnhancer tokenEnhancer = new CustomTokenEnhancer(user.getUserID());

        CustomTokenServices tokenServices = new CustomTokenServices();
        tokenServices.setTokenEnhancer(tokenEnhancer);
        tokenServices.setSupportRefreshToken(true);
        tokenServices.setTokenStore(tokenStore);

        OAuth2AccessToken accessToken = tokenServices.createAccessTokenForUser(authenticationRequest, user);
