原因及解决办法:https://docs.spring.io/spring-boot/docs/2.0.3.RELEASE/reference/htmlsingle/#howto-use-tomcat-legacycookieprocessor

@Configuration
public class CookieConfig {
 
    /**
     * 解决问题:
     * There was an unexpected error (type=Internal Server Error, status=500).
     * An invalid domain [.localhost.com] was specified for this cookie
     *
     * @return
     */
    @Bean
    public WebServerFactoryCustomizer<TomcatServletWebServerFactory> cookieProcessorCustomizer() {
        return (factory) -> factory.addContextCustomizers(
                (context) -> context.setCookieProcessor(new LegacyCookieProcessor()));
    }
}

补充cookie坑,同一个服务器,前端访问IP地址cookie存在IP地址下,访问域名cookie存在域名下
