jsp的奇特的一个乱码问题。

PrintWriter out = response.getWriter();//request.setCharacterEncoding("UTF-8");//response.setCharacterEncoding("UTF-8");//response.setContentType("text/html; charset=UTF-8");System.out.println("dddd");RequestDispatcher rd = request.getRequestDispatcher("/WEB-INF/view/index.jsp");rd.forward(request, response);

printWriter out 行会造成乱码，注释就好，如果想用 out  要在之前设 编码.·
