GAE datastore
Refer to this official “Using datstore guide” to understand what is GAE datastore.
Refer to this official “Using datstore guide” to understand what is GAE datastore.
See following code snippets to perform CRUD for Google App Engine datastore, Java, using low-level API.
Add
Store a customer into datastore, with “name” as the key.
Key customerKey = KeyFactory.createKey("Customer", "your name");
Entity customer = new Entity("Customer", customerKey);
customer.setProperty("name", "your name");
customer.setProperty("email", "your email");
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
datastore.put(customer); //save it
Search
Return 10 customers as a List.
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
Query query = new Query("Customer").addSort("date", Query.SortDirection.DESCENDING);
List<Entity> customers = datastore.prepare(query).asList(FetchOptions.Builder.withLimit(10));
Find and returned a customer with matched filter.
Query query = new Query("Customer");
query.addFilter("name", FilterOperator.EQUAL, "your name");
PreparedQuery pq = datastore.prepare(query);
Entity customer = pq.asSingleEntity();
FilterOperator.EQUAL
Play this filters, it has few condition options, like less than, great than and etc.
Play this filters, it has few condition options, like less than, great than and etc.
Update
To update, just modify the existing Entity and save it again.
Query query = new Query("Customer");
query.addFilter("name", FilterOperator.EQUAL, "your name");
PreparedQuery pq = datastore.prepare(query);
Entity customer = pq.asSingleEntity();
customer.setProperty("name", name);
customer.setProperty("email", email);
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
datastore.put(customer); //GAE will know save or update
Delete
To delete, need the entity key.
Query query = new Query("Customer");
query.addFilter("name", FilterOperator.EQUAL, name);
PreparedQuery pq = datastore.prepare(query);
Entity customer = pq.asSingleEntity();
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
datastore.delete(customer.getKey()); //delete it
GAE + Spring MVC + CRUD example
Ok, now we will show you a simple web application developed using Spring MVC in REST style, manipulate data in Google App Engine datastore, using low-level APIs above.
- Google App Engine Java SDK 1.6.3.1
- Spring 3.1.1
- JDK 1.6
- Eclipse 3.7 + Google Plugin for Eclipse
Note
This example is keep into as simple as possible, to show you how to perform CRUD only, no layers like DAO or BO, no validation or message notification of the success or failed action.

1. Spring Controller
Spring controller, REST style, to display the web page and perform the CRUD. The code should be self-explanatory.
File : CustomerController.java
package com.mkyong.controller;
import java.util.Date;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.google.appengine.api.datastore.DatastoreService;
import com.google.appengine.api.datastore.DatastoreServiceFactory;
import com.google.appengine.api.datastore.Entity;
import com.google.appengine.api.datastore.FetchOptions;

import com.google.appengine.api.datastore.PreparedQuery;
import com.google.appengine.api.datastore.Query;
import com.google.appengine.api.datastore.Query.FilterOperator;
@Controller
@RequestMapping("/customer")
public class CustomerController {
@RequestMapping(value="/addCustomerPage", method = RequestMethod.GET)
public String getAddCustomerPage(ModelMap model) {
return "add";
}
@RequestMapping(value="/add", method = RequestMethod.POST)
public ModelAndView add(HttpServletRequest request, ModelMap model) {
String name = request.getParameter("name");
String email = request.getParameter("email");
Key customerKey = KeyFactory.createKey("Customer", name);
Date date = new Date();
Entity customer = new Entity("Customer", customerKey);
customer.setProperty("name", name);
customer.setProperty("email", email);
customer.setProperty("date", date);
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
datastore.put(customer);
return new ModelAndView("redirect:list");
}
@RequestMapping(value="/update/{name}", method = RequestMethod.GET)
public String getUpdateCustomerPage(@PathVariable String name,
HttpServletRequest request, ModelMap model) {
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
Query query = new Query("Customer");
query.addFilter("name", FilterOperator.EQUAL, name);
PreparedQuery pq = datastore.prepare(query);
Entity e = pq.asSingleEntity();
model.addAttribute("customer", e);
return "update";
}
@RequestMapping(value="/update", method = RequestMethod.POST)
public ModelAndView update(HttpServletRequest request, ModelMap model) {
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
String name = request.getParameter("name");
String email = request.getParameter("email");
String originalName = request.getParameter("originalName");
Query query = new Query("Customer");
query.addFilter("name", FilterOperator.EQUAL, originalName);
PreparedQuery pq = datastore.prepare(query);

customer.setProperty("name", name);
customer.setProperty("email", email);
customer.setProperty("date", new Date());
datastore.put(customer);
//return to list
return new ModelAndView("redirect:list");
}
@RequestMapping(value="/delete/{name}", method = RequestMethod.GET)
public ModelAndView delete(@PathVariable String name,
HttpServletRequest request, ModelMap model) {
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
Query query = new Query("Customer");
query.addFilter("name", FilterOperator.EQUAL, name);
PreparedQuery pq = datastore.prepare(query);
Entity customer = pq.asSingleEntity();
datastore.delete(customer.getKey());
//return to list
return new ModelAndView("redirect:../list");
}
//get all customers
@RequestMapping(value="/list", method = RequestMethod.GET)
public String listCustomer(ModelMap model) {
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
Query query =
new Query("Customer").addSort("date", Query.SortDirection.DESCENDING);
List<Entity> customers =
datastore.prepare(query).asList(FetchOptions.Builder.withLimit(10));
model.addAttribute("customerList", customers);
return "list";
}
}
2. JSP Pages
3 JSP pages to display customer and perform add and update.
File : list.jsp
<%@ page import="java.util.List" %>
<%@ page import="com.google.appengine.api.datastore.Entity" %>
<html>
<body>
<h1>GAE + Spring 3 MVC REST + CRUD Example</h1>
Function : <a href="addCustomerPage">Add Customer</a>
<hr />
<h2>All Customers</h2>
<table border="1">
<thead>
<tr>
<td>Name</td>
<td>Email</td>
<td>Created Date</td>
<td>Action</td>
</tr>
</thead>
<%
List<Entity> customers = (List<Entity>)request.getAttribute("customerList");
for(Entity e : customers){
%>
<tr>
<td><%=e.getProperty("name") %></td>
<td><%=e.getProperty("email") %></td>

<table>
<tr>
<td>
UserName :

<input type="submit" class="update" title="Update" value="Update" />
</form>
</body>
</html>
3. Spring Configuration
Scan the Spring controller and configure the view resolver, so that it can redirect the view to jsp pages.
File : mvc-dispatcher-servlet.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<context:component-scan base-package="com.mkyong.controller" />
<mvc:annotation-driven />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">

5. Demo
Done, see demo and show you the workflow of the web application.
1. A listing page, to display list of existing customers.
URL : http://localhost:8888/customer/list
2. In listing page, click on the “Add Customer” link to display the add customer page, fill in a new customer, and click on the “Add” button.
URL : http://localhost:8888/customer/addCustomerPage
3. After saved the customer, it will return back to the listing page.
URL : http://localhost:8888/customer/list
4. Try update link, it will display the selected customer’s data, update email address and click on the update button.
URL : http://localhost:8888/customer/update/mkyong
5. The email is updated, and redirect back to listing page.
URL : http://localhost:8888/customer/list
6. To delete the customer, just click on the “delete” link.
