servlet 頁面中文亂碼

頁面:
程式碼:
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { PrintWriter out = resp.getWriter(); out.println("<html>"); out.println("<body>"); out.println("<h1>使用者登入<h1>"); out.println("<form action=\"\" method=\"\">"); out.println("<p>使用者名稱:<input type=\"text\" name=\"name\" /></p>"); out.println("<p>密碼:<input type=\"password\" name=\"pwd\" /></p>"); out.println("<p><input type=\"submit\" value=\"登入\" /></p>"); out.println("</form>"); out.println("</body>"); out.println("</html>"); }
修改後:
頁面:
程式碼:
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { // 這一行一定要在 getWriter() 前面 resp.setCharacterEncoding("utf-8"); PrintWriter out = resp.getWriter(); out.println("<html>"); // 加上這一行 out.println("<meta http-equiv=\"content-type\" content=\"text/html\" charset=\"utf-8\"/> "); out.println("<body>"); out.println("<h1>使用者登入<h1>"); out.println("<form action=\"\" method=\"\">"); out.println("<p>使用者名稱:<input type=\"text\" name=\"name\" /></p>"); out.println("<p>密碼:<input type=\"password\" name=\"pwd\" /></p>"); out.println("<p><input type=\"submit\" value=\"登入\" /></p>"); out.println("</form>"); out.println("</body>"); out.println("</html>"); }
