在这里插入图片描述

原因

大致问题就是从Tomcat 8，Cookie的解析已经符合RFC 6265。由于RFC 6265不再接受以前允许的逗号分隔符（例如RFC 2109） "Cookie：KEY 1 = VAL 1，KEY 2 = VAL 2"的格式所以被视为非法。

解决办法
在启动类上加入以下代码:

  @Bean
    public WebServerFactoryCustomizer<TomcatServletWebServerFactory> cookieProcessorCustomizer() {
        return tomcatServletWebServerFactory -> tomcatServletWebServerFactory.addContextCustomizers((TomcatContextCustomizer) context -> {
            context.setCookieProcessor(new LegacyCookieProcessor());
        });
    }
