如何知道令牌已过期（SpringBoot Oauth2）？

Question

我需要发回两个不同的错误消息以获取无效令牌和过期令牌。

我怎么知道令牌过期错误？我没有找到ExpiredTokenException类 仅找到ExpiringOAuth2RefreshToken类。下面是我的代码示例。

欢迎任何建议或提示！

import org.springframework.security.core.AuthenticationException;
import org.springframework.security.oauth2.common.exceptions.InvalidTokenException;
@Component
public class AuthExceptionEntryPoint implements AuthenticationEntryPoint {

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws ServletException {
        Map<String, Object> map = new HashMap<String, Object>();
        Throwable cause = authException.getCause();

        response.setStatus(HttpStatus.SC_OK);
        response.setHeader("Content-Type", "application/json;charset=UTF-8");
        try {
            ResultVO resultVO = new ResultVO();
            if(cause instanceof InvalidTokenException) {
                resultVO.setStatus(false).setErrmsg("INVALID_TOKEN").setData(null);
                response.getWriter().write(JSONObject.toJSONString(resultVO));
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
