[https-jsse-nio-443-exec-9] INFO org.apache.coyote.http11.Http11Processor - Error parsing HTTP request header

Note: further occurrences of HTTP request parsing errors will be logged at DEBUG level.

java.lang.IllegalArgumentException: Invalid character found in the request target [/sra_{BA195980-CD49-458b-9E23-C84EE0ADCD75}/ ]. The valid characters are defined in RFC 7230 and RFC 3986

at org.apache.coyote.http11.Http11InputBuffer.parseRequestLine (Http11InputBuffer.java)

at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:269) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:65) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:893) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1723) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Unknown Source)

原因：

SpringBoot 2.0.0 以上都采用内置tomcat8.0以上版本，而tomcat8.0以上版本遵从RFC规范添加了对URL的特殊字符的限制，URL中只允许包含英文字母(a-zA-Z)、数字(0-9)、-_.~四个特殊字符以及保留字符( ! * ’ ( ) ; : @ & = + $ , / ? # [ ] ) (262+10+4+18=84) 这84个字符，如果请求中出现其他符号就会导致tomcat报此错误

解决方式：

   @Beanpublic ConfigurableServletWebServerFactory webServerFactory() {TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {@Overridepublic void customize(Connector connector) {connector.setProperty("relaxedQueryChars", "|{}[]");connector.setProperty("relaxedPathChars", "|{}[]");}});return factory;}
