jsp url传递参数乱码

      废话不多说了，方案有两种：

一.request.setCharacterEncoding("utf-8");

    String str = new String(request.getParameter("id").getBytes("iso8859-1"), "utf-8");

二.改变tomcat对url的编码

    在server.xml中进行设置：

<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="utf-8" useURIEncoding="true"/> 

然后request.setCharacterEncoding("utf-8");
