Spring Data REST Keycloak - 处理 token 不是事件异常？

Question

我将 Keycloak 与 Spring Data REST 结合使用，如果用户发送带有过期 token 的 http 请求，则会引发以下异常

我不想让应用程序抛出异常，而是想处理异常并向用户发送自定义错误消息。我已经有一个 ExceptionHandler 类来处理 Controller 中抛出的任何错误

@ControllerAdvice
public class RestExceptionHandler extends ResponseEntityExceptionHandler {

//code

}

但是，此异常是在 Controller 方法之外抛出的，因此它不会被 RestExceptionHandler 类处理。那么如何检查用户的 token 是否过期，然后向用户发送自定义错误响应？

Answer 1

最终是 Spring Security 调用 keycloak 适配器进行身份验证，因此您最好查看 spring security ways of doing this customization而不是查看 Controller 级别

如果您从 UI 调用后端并且发现 token 过期很多，那么您可能会查看 keycloak js 适配器，因为我认为它应该有助于做到这一点
