19行的语句解决不了乱码问题。
参照网上找到了解决的方法：找到Tomcat安装目录下的conf文件中的server.xml
1 <Connector port="8080" protocol="HTTP/1.1" 2 connectionTimeout="20000" 3 redirectPort="8443" />
添加两行代码：URIEncoding="UTF-8" useBodyEncodingForURI="true"
添加后如下
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" URIEncoding="UTF-8" useBodyEncodingForURI="true" redirectPort="8443" />
解决如图
