从Edgware（春季启动1.x）到格林威治（春季启动2.x）的Spring Cloud升级失败

Question

网关身份验证成功后，从Edgware（春季启动1.x）升级到Finchely / Greenwich（春季启动2.x）的Spring Cloud失败，但是在网页中显示403禁止访问。我正在升级Spring Cloud，我可以在最新的Spring Cloud版本中看到一些工件更改，并且已经对其进行了更新，但不幸的是，登录到应用程序后它抛出403 access拒绝错误。如果我使用Edgware（Spring boot 1 .x）版本。

在调试我为类“ UsernamePasswordAuthenticationToken”传递参数后找到的代码时，它进入springframwork类，并且永远不会从spring库中退出。

@Service（值=“ AuthProvider”） 公共最终类AuthProvider实现AuthenticationProvider {     私有静态最终Logger logger = LoggerFactory.getLogger（AuthProvider.class）;

@Autowired
UserAuthenticationService userAuthenticationService;

@Override
public Authentication authenticate(Authentication authentication)throws AuthenticationException
{
    UsernamePasswordAuthenticationToken userToken = (UsernamePasswordAuthenticationToken) authentication;

    List<String> roles = userAuthenticationService.authenticate(userToken.getName(),
            userToken.getCredentials().toString());

    if (roles.size() > 1 && roles.get(0).equals("FINE"))
    {
        Collection<GrantedAuthority> authorities = new ArrayList<>();
        for (String role : roles.subList(1, roles.size()))
        {
            authorities.add(new SimpleGrantedAuthority(role));
        }
        return new UsernamePasswordAuthenticationToken(userToken.getName(), userToken.getCredentials(),
                authorities); --> **at this point it enters into spring libraries and it never comes out of it.**

    }
    // User has an FINE in the first position of the list,there are no roles
    // (size = 1)
    else if (roles.size() == 1 && roles.get(0).equals("FINE"))
    {
        JSONObject json = new JSONObject();
        try
        {
            json.put("errorCode", "FFF");
        }
        catch (JSONException e)
        {
            logger.warn("AuthProvider: Unexpected error", e);
        }

        throw new BadCredentialsException(json.toString());
    }
    // User has an JSON-message error in the first position of the list
    else
    {
        throw new BadCredentialsException(roles.get(0));
    }
}

}
