Java Spring boot 2 kerberos身份验证

我想知道如何在SpringBoot2.0中使用SpringSecurityKerberos

我们目前正在尝试使SPNego过滤器工作

这就是错误：

o.s.s.k.w.a.SpnegoAuthenticationProcessingFilter : Negotiate Header was invalid: Negotiate YHoGBisGAQUFAqBwMG6gMDAuBgorBgEEAYI3AgIKBgkqhkiC9xIBAgIGCSqGSIb3EgECAgYKKwYBBAGCNwICHqI6BDhOVExNU1NQAAEAAACXsgjiAwADADUAAAANAA0AKAAAAAYBsR0AAAAPSU5CT01WRDgxMTAzMURCRw==

目前，我们仅尝试对单个端点进行身份验证（

/protected

），但我们需要使用kerberos身份验证来保护所有端点。 这是web安全配置（相同的代码适用于Spring Boot 1.5.13.RELEASE，但不适用于Spring Boot 2.0.3.RELEASE）：
