Question

我有一个演示代码，其中有三个名为arabic1.jsp，arabic2.jsp，arabic3.jsp的jsp和一个名为ArabicServlet的servlet。

在arabic1.jsp内我有一个文本框，我在其中输入了阿拉伯语值并通过调用ArabicServlet servlet提交了页面，该文件将相同的内容转发到arabic2.jsp，其中我在其中显示了相同的内容正确显示的文本框。

现在我在arabic2.jsp上有一个链接使用相同的servlet和内容转发arabic3.jsp上的请求，arabic3.jsp我在文本框中显示了相同的阿拉伯语内容，但我的字符错误。

我在第一个jsp上输入值محمد，它在第三个jsp显示为ÙØÙØ¯

ArabicServlet.java

    request.setCharacterEncoding("UTF-8");
    String page = request.getParameter("page");
    System.out.println("Page Number = "+page);

    if(page.equals("1")){
        String arabic = (String)request.getParameter("arabic");
        System.out.println("Arabic Value from first page = "+arabic);

        Map map = new java.util.Hashtable();
        map.put("arabicmap",arabic);
        request.setAttribute("arabic",map);
        request.getRequestDispatcher("arabic2.jsp").forward(request,response);
    }else{

Answer 1

我通过在代码中添加以下行来解决类似的问题：

  request.setCharacterEncoding("UTF-8");
  response.setCharacterEncoding("UTF-8");

阿拉伯语值在jsp servlet中不起作用
