Figure 10.8
The distributed Fancy Foods system includes two frameworks. The original framework
includes a new
fancyfoods.remote.config
bundle; the remote framework reuses some Fancy
Foods bundles and adds a new
fancyfoods.department.foreign
bundle.
The first thing you need is an implementation for your remote service.
10.3.1
Coding a special offer service
To simplify things, your
SpecialOffer
implementation is effectively identical to the
cheese department one, with a slightly different query, as shown in the following listing.
Listing 10.1
A foreign foods special offer service
public class ForeignFoodOffer implements SpecialOffer {
private Inventory inventory;
public void setInventory(Inventory inventory) {
this.inventory = inventory;
}
@Override
public String getDescription() {
return "Something exotic to spice up your weekend.";
}
@Override
public Food getOfferFood() {
List<Food> foods =
inventory.getFoodsWhoseNameContains("Foreign", 1);
Food mostStocked = foods.get(0);
return mostStocked;
}
}
