方案一、
Tomcat官网给出的方案：
http://tomcat.apache.org/tomcat-8.0-doc/config/systemprops.html

tomcat.util.http.parser.HttpParser. requestTargetAllow
    
This system property is deprecated. Use the relaxedPathChars and relaxedQueryChars attributes of the Connector instead. These attributes permit a wider range of characters to be configured as valid.

A string comprised of characters the server should allow even when they are not encoded. These characters would normally result in a 400 status.

The acceptable characters for this property are: |, { , and }

WARNING: Use of this option may expose the server to CVE-2016-6816.

If not specified, the default value of null will be used.

方案二、
修改server.xml 配置

tomcat --> conf--> server.xml 

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
               URIEncoding="utf-8" relaxedPathChars="|{}[],%"
               relaxedQueryChars="|{}[],%"
               />
