爲什麼url顯示/ ServletName，雖然顯示的是從jsp

我有一個servlet，我從Sql Server使用ResultSet獲取數據。我使用 request.setAttribute("list", list); request.getRequestDispatcher("Display.jsp").forward(request, response);在jsp中顯示爲表格。爲什麼url顯示/ ServletName，雖然顯示的是從jsp

但在Chrome的多功能框中，我看到/ ServletName而不是/JSPName.jsp。根據從servlet接收到的list，該表使用foreach在jsp中顯示。

這是servlet：

protected void doGet(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 
    response.setContentType("text/html"); 
    PrintWriter out = response.getWriter(); 

    Connection connection = null; 
    Statement stmt = null; 



    try { 
     StringBuffer data = null; 
     try { 
      Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
     } catch (ClassNotFoundException ex) { 
      Logger.getLogger(NewServlet.class.getName()).log(Level.SEVERE, null, ex); 
     } 
     connection = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=DesktopScreen","sa","sa123"); 
     stmt = connection.createStatement(); 
     ArrayList list = new ArrayList(); 
     String query = "select * from ClientLogin"; 
     ResultSet rs = stmt.executeQuery(query); 
     while (rs.next()) { 
      String UniqueId,ClientId,RequestedDateTime,ConnectionStatus; 
      UniqueId = rs.getString("UniqueID"); 
      ClientId = rs.getString("ClientId"); 
      RequestedDateTime = rs.getString("RequestDateTime"); 
      ConnectionStatus = rs.getString("ConnectionStatus"); 
      BeanClass beanClass = new BeanClass(); 
      beanClass.setUniqueId(UniqueId); 
      beanClass.setClientId(ClientId); 
      beanClass.setConnectionStatus(ConnectionStatus); 
      beanClass.setRequestDateTime(RequestedDateTime); 

      list.add(beanClass); 

     } 
     request.setAttribute("list", list); 
     request.getRequestDispatcher("Display.jsp").forward(request, response); 
    } 
    catch (SQLException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    finally 
    { 

     try { 
      connection.close(); 
     } catch (SQLException ex) { 
      Logger.getLogger(NewServlet.class.getName()).log(Level.SEVERE, null, ex); 
     } 

    } 
}

這是Display.jsp：

<table border ="1" style="border: border-collapse"> 
     <tr><td>UniqueId</td><td>ClientId</td><td>Request Date and Time</td><td>Connection Status</td></tr> 
    <c:forEach items="${list}" var="item"> 
     <tr> 
      <td>${item.getUniqueId()}</td> 
      <td>${item.getClientId()}</td> 
      <td>${item.getRequestDateTime()}</td> 
      <td>${item.getConnectionStatus()}</td> 
     </tr> 
    </c:forEach> 
    </table>

'forward'方法不會更改瀏覽器的網址。嘗試['sendRedirect']（http://www.javatpoint.com/sendRedirect（） - 方法）。閱讀[JSP Servlet中的SendRedirect（）和Forward（）之間的區別]（http://javarevisited.blogspot.com/2011/09/sendredirect-forward-jsp-servlet.html#ixzz41izgW1fO） – Braj
