jsp 设置了request.setCharacterEncoding("gbk")还是出现了乱码
<%
  request.setCharacterEncoding("gbk");
  String tname = request.getParameter("tname");
  System.out.println(tname);
  TopicDAO add = new TopicDAOImpl();
  boolean result = add.addTopic(tname);
  if (result) {
  out.print("成功");
  } else {
  out.print("失败");
  }
  %>

这里面输出tname的还是乱码.

------解决方案--------------------
在传tname页面也要设置编码
