解决页面传参到控制器时的乱码问题

方法一:

String reachName=new String(((request.getParameter("reachName")==null||"".equals(request.getParameter("reachName")))?"":request.getParameter("reachName")).getBytes("iso-8859-1"),"utf-8");

方法二:

在tomcat中server.xml这个配置文件中改为一下编码URIEncoding="UTF-8",

<Connector URIEncoding="UTF-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
