1，拉取最新版本，仍然经常报下面的错误：
java.lang.IllegalArgumentException: The character [3] is not valid after a period in a domain name
2，详细异常信息如下：
org.apache.coyote.http11.Http11Processor.parseHost The host header [www. 域名.com:8080] failed validation with the error [The character [3] is not valid after a period in a domain name.]. Processing of the request will continue but Tomcat will reject these requests with a 400 response in a future release.
Note: further occurrences of HTTP request parsing errors will be logged at DEBUG level.
java.lang.IllegalArgumentException: The character [3] is not valid after a period in a domain name.
