最佳答案
Tomcat8.5.33 不允许在 URL 中使用特殊字符，例如 |{}[]。
有两种方法可以避免这种错误。
如果您的特殊字符是 |{} 之一，您可以直接添加配置 conf\catalina.properties，如下所示:
tomcat.util.http.parser.HttpParser.requestTargetAllow=|{}
如果你的特殊字符是其他字符，你可以像下面这样配置conf\server.xml:
<Connector port="8075" protocol="HTTP/1.1" relaxedQueryChars='|[]'
connectionTimeout="20000"
redirectPort="8443" />
