> ### An invalid domain \[\] was specified for this cookie问题解决方案 ###

**1.【问题描述】： 项目运行在Tomcat 8.5.30上启动报出An invalid domain \[\] was specified for this cookie，报错行：在某个filter中设置顶层域名cookie，原因：该Tomcat版本下域名验证的时候错误了，不符合Tomcat 8.5.30验证规则**

**2.【跟踪addCookie方法****】：tomcat8.5版本默认使用的是rfc6265实现的，而tomcat8.0版本是LegacyCookieProcessor**

**3.【rfc6265中看到了域属性规则】：**

规则：

**（1）必须是1-9、a-z、A-Z、. 、- （注意是-不是\_）这几个字符组成**

**（2）必须是数字或字母开头 （[所以以前的cookie的设置为.XX.com][cookie_.XX.com] 的机制要改为 [XX.com][] 即可）**

**（3）必须是数字或字母结尾**

**（4）cookie.setDomain(".test.com");在rfc6265标准中应该改为cookie.setDomain(“[test.com][]”)**

**4.【解决方案一】：**

**修改配置 $\{tomcat\_home\}\\conf\\context.xml文件**

<?xml version="1.0" encoding="UTF-8”?>
    
    <Context>
    
    
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
    <WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>
    
    
    
    <CookieProcessor className="org.apache.tomcat.util.http.LegacyCookieProcessor"/>
    </Context>

**5.****【解决方案二】： **

**SpringBoot项目遇到上述错误，配置下面Bean:**

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