当url链接里有|{}三个字符串会报错:

 o.apache.coyote.http11.Http11Processor : Error parsing HTTP request header Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level. java.lang.IllegalArgumentException: Invalid character found in method name.

可以做一下设置:

 public static void main(String[] args) { SpringApplication.run(Application.class, args); //指定jre系统属性,允许 特殊符号 | 做入参 详情见 tomcat HttpParser类 System.setProperty("tomcat.util.http.parser.HttpParser.requestTargetAllow","|,{,}"); }
