有人知道如何解决这些问题吗？我在catalina.out日志中看到了这一点，有时会有多个用户登录。我用的是tomcat9。我见过一些帖子说它将在Tomcat8.5之后的更高版本中修复，但看起来不是这样。

其他时候，它在日志中有这样的内容（同样是在多个用户登录的情况下）：

发生这种情况后，cpu利用率变高，ec2示例被终止。它实际上增加了cpu利用率吗？我假设这是两个不同的问题。有人能证实这一点吗？
我见过一些帖子说在server.xml中添加宽松的查询字符，但这是正确的方法吗？这难道不意味着在安全上妥协吗？
解决这个问题的最好办法是什么？在xml中添加relaxedquery字符是解决这个问题的好方法吗？因为springboot http防火墙安全性已经阻止了非法字符，如斜杠、分号、百分比等。

您看到的信息消息是由于客户端中的各种错误造成的：
http/1.1请求的格式（如rfc 7230所述）是以字符结尾的一系列行 CR （十六进制 0x0d )及 LF （十六进制 0x0a ). 发出请求的客户端仅使用 LF . tomcat过去更为宽容和接受 LF 终止行：参见“bug”65272，
第二条消息报告尝试使用tls（初始帧以字节开始） 0x16 及 0x03 )在普通http连接器上。很可能是由于写得不好的端口扫描程序导致了上一条消息：由于http请求失败，它尝试了https，
剩余的消息是由于uri路径缺少正确的url编码造成的。同样，这些可能是端口扫描程序，它们试图触发某些php软件中的错误，只需忽略它们。
一般来说，您可能会忽略所有这些消息。如果他们打扰你，你可以在tomcat前面放置一个反向代理，比如nginx，并使用一些fail2ban规则将发出这些请求的IP列入黑名单。
