Package io.ebean Description

Core API (see EbeanServer and Ebean).

Ebean

Provides the main API for fetching and persisting beans with eBean.

// EXAMPLE 1: Simple fetch
//========================

// fetch order 10
Order order = Ebean.find(Order.class, 10);



// EXAMPLE 2: Fetch an Object with associations
//=============================================

// fetch Customer 7 including their billing and shipping addresses
Customer customer =
        Ebean.find(Customer.class)
                .setId(7)
                .fetch("billingAddress")
                .fetch("shippingAddress")
                .findOne();

Address billAddr = customer.getBillingAddress();
Address shipAddr = customer.getShippingAddress();




// EXAMPLE 3: Create and save an Order
//=====================================

// get a Customer reference so we don't hit the database
Customer custRef = Ebean.getReference(Customer.class, 7);

// create a new Order object
Order newOrder = new Order();
newOrder.setStatus(Order.Status.NEW);
newOrder.setCustomer(custRef);

ArrayList orderLines = new ArrayList();
newOrder.setLines(orderLines);
...

// add a line to the order
Product prodRef = Ebean.getReference(Product.class, 41);
OrderLine line = new OrderLine();
line.setProduct(prodRef);
line.setQuantity(10);
orderLines.add(line);
...

// save the order and its lines in a single transaction
// NB: assumes CascadeType.PERSIST is set on the order lines association
Ebean.save(newOrder);



// EXAMPLE 4: Use another database
//=================================

// Get access to the Human Resources EbeanServer/Database
EbeanServer hrServer = Ebean.getServer("HR");


// fetch contact 3 from the HR database
Contact contact = hrServer.find(Contact.class, 3);

contact.setStatus(Contact.Status.INACTIVE);
...

// save the contact back to the HR database
hrServer.save(contact);
