我正在尝试使用spring-kerberos-core和spring-data-redis编写一个应用程序。
当我使用JdkSerializationRedisSerializer时，在第二个应用程序中出现错误
java.lang.ClassNotFoundException: ru.demo.app2.CustomUser not found
这是合乎逻辑的，因为我创建了自己的类来扩展org.springframework.security.core.userdetails.User.class的类。第一个应用程序和第二个应用程序中的用户对此一无所知。
但是当我使用GenericJackson2JsonRedisSerializer时，出现异常：
org.springframework.data.redis.serializer.SerializationException: Could not write JSON: No valid credentials provided (through reference chain: org.springframework.security.core.context.SecurityContextImpl["authentication"]->org.springframework.security.kerberos.authentication.KerberosServiceRequestToken["ticketValidation"]->org.springframework.security.kerberos.authentication.KerberosTicketValidation["gssContext"]->sun.security.jgss.GSSContextImpl["delegCred"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: No valid credentials provided (through reference chain: org.springframework.security.core.context.SecurityContextImpl["authentication"]->org.springframework.security.kerberos.authentication.KerberosServiceRequestToken["ticketValidation"]->org.springframework.security.kerberos.authentication.KerberosTicketValidation["gssContext"]->sun.security.jgss.GSSContextImpl["delegCred"])

这是我对Bean的定义：
@Bean
public RedisSerializer<Object> springSessionDefaultRedisSerializer() {
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new WebJackson2Module());
return new GenericJackson2JsonRedisSerializer(mapper);
}
UPD1 也许我得到的错误是另一个异常的结果
