中文乱码

①设置tomcat编码问题

    在tomcat的conf文件里面找到server.xml     

   <Connector useBodyEncodingForURI="true"  URIEncoding="UTF-8" maxThreads="150" port="8888" protocol="HTTP/1.1" redirectPort="8443">

   useBodyEncodingForURI="true" ：表示get和post都用同一中编码

   URIEncoding="UTF-8" ：表示对url使用utf-8进行编码

②使用springmvc框架时，提交表单中文乱码
