<%
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());

尝试在 app.js 而不是视图上添加它，这将删除警告。

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

尝试在xtype:'bloglist',. 我认为这将处理您收到的警告。

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