Package com.avaje.ebean Description

Core API (see Ebean and EbeanServer).

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")
                        .findUnique();  
        
        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);
