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
