oauth2 远程调用问题

两个项目远程调用时发生问题，一直找不到原因，报错代码行如下：

java.lang.ClassCastException: java.lang.String cannot be cast to java.time.Instant
    at org.springframework.security.oauth2.server.resource.authentication.OpaqueTokenReactiveAuthenticationManager.lambda$authenticate$0(OpaqueTokenReactiveAuthenticationManager.java:89)

需要转换一下数据类型，参数传过来的是时间为秒的时间戳
long l = Long.parseLong("1638359117") * 1000;
Instant instant = Instant.ofEpochMilli(l) ;
