SpringBoot - 解析HTTP请求标头时出错

Question

我正在运行SpringBoot Application刚检查的服务器日志,并得到了这样的几个错误.由于每天12/24小时后出现错误,我无法理解是什么原因造成的.

运行Tomcat版本 8.5.11

2018-03-04 17:03:26 [http-nio-8080-exec-85] INFO  o.a.coyote.http11.Http11Processor - Error parsing HTTP request header

Answer 1

正如我在这个类似的问题中回答的那样，请检查您是否意外地使用 HTTPS 协议而不是 HTTP 协议进行请求。如果您没有在 Tomcat 上配置 SSL 并发送 HTTPS 请求，则会出现此奇怪的消息。

Answer 2

这可能是因为解析HTTPS标头而不是HTTP.尝试:

1. 添加:
   logging.level.org.springframework.web: trace
logging.level.org.apache: trace
   到你的application.properties,看看Spring对你说了什么.
2. 检查当时是否有任何计划活动,这些活动是指SSL加密的其他资源.另请参见:java.lang.IllegalArgumentException:在方法名称中找到无效字符.HTTP方法名称必须是令牌
