4.42. Java Binding Example
This Order message example shows how to bind it into a corresponding Java Object model.
The message input:
<order xmlns="http://x">
<header>
<y:date xmlns:y="http://y">Wed Nov 15 13:45:28 EST 2006</y:date>
<customer number="123123">Joe</customer>
<privatePerson></privatePerson>
</header>
<order-items>
<order-item>
<product>111</product>
<quantity>2</quantity>
<price>8.90</price>
</order-item>
<order-item>
<product>222</product>
<quantity>7</quantity>
<price>5.20</price>
</order-item>
</order-items>
</order>
The Java Model (not including getters/setters):
public class Order {
private Header header;
private List<OrderItem> orderItems;
}
public class Header {
private Long customerNumber;
private String customerName;
}
public class OrderItem {
private long productId;
private Integer quantity;
private double price;
}
The configuration code:
Smooks smooks = new Smooks();
Bean orderBean = new Bean(Order.class, "order", "/order");
orderBean.bindTo("header",
orderBean.newBean(Header.class, "/order")
.bindTo("customerNumber", "header/customer/@number")
.bindTo("customerName", "header/customer")
).bindTo("orderItems",
orderBean.newBean(ArrayList.class, "/order")
.bindTo(orderBean.newBean(OrderItem.class, "order-item")
.bindTo("productId", "order-item/product")
.bindTo("quantity", "order-item/quantity")
.bindTo("price", "order-item/price"))
);
smooks.addVisitors(orderBean);
The execution code:
JavaResult result = new JavaResult();
smooks.filterSource(new StreamSource(orderMessageStream), result);
Order order = (Order) result.getBean("order");
Here is an example where an anonymous Factory class is defined and used:
Bean orderBean = new Bean(Order.class, "order", "/order", new Factory<Order>() {
public Order create(ExecutionContext executionContext) {
return new Order();
}
});
