Question

我有以下jsp页面。它正在显示结果。

enter code here


<%@page language="java" import="java.sql.*, java.util.*, java.lang.*, net.sf.json.*,       org.json.simple.JSONObject" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"  %>



<%
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/thermo?user=root&password=");
Statement statement = connection.createStatement();
ResultSet result = statement.executeQuery("select model_number from product");

JSONObject json      = new JSONObject();
JSONArray  addresses = new JSONArray();
//JSONObject address =new JSONObject();
    while(result.next())
    {
        //address.put(result.getString("model_number"));
        addresses.add(result.getString("model_number"));
    }
    json.put("Addresses", addresses);
    out.println(addresses);

response.setContentType("application/json");
response.getWriter().write(json.toString());
}
    catch (JSONException jse)
{ 

}
%>

Thank you.

Answer 1

尝试在app.js上添加此项而非视图，这将删除警告。

requires: ['Ext.data.Store', 'Ext.data.proxy.JsonP', 'Ext.dataview.List'],

Answer 2

尝试在xtype:'bloglist',之后添加以下行。我认为这会照顾你得到的警告。

requires: ['Ext.data.proxy.JsonP'],

我使用JSP从数据库中检索数据，我想在使用senchatouch2时显示该数据列表？
