再Tomcat根目录下的config.xml文件，找到<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
再其中添加：URIEncoding="UTF-8" 和 useBodyEncodingForURI=“true”
useBodyEncodingForURI
（默认false）：参数表示是否用 与 request.setCharacterEncoding一致的编码
如果是true，参数对URL提交的数据和表单中GET方式提交的数据进行重新编码。
URIEncoding （默认ISO8859-1）参数指定对所有GET方式请求进行统一的重新编码（解码）的编码。
再Tomcat8中，关于URIEncoding的描述做出了更改：http://localhost:8080/docs/config/http.html
URIEncoding |
This specifies the character encoding used to decode the URI bytes, after %xx decoding the URL. If not specified, UTF-8
will be used unless the |
PS:极其不建议在Tomcat的配置文件上做编码的修改，因为你不知道用户用的什么版本或根本就不是Tomcat，总不能和用户说：你用tomcat 吧，再顺便那个配置文件改改
