DAO Fusion 介绍
DAO Fusion 是一个轻量级的，但功能完整具备可扩展性的实现了 DAO 设计模式的 Java 框架，基于 JPA 和 Hibernate 构建。
示例代码：
@Entity
@Table(name = "customers",
uniqueConstraints = {@UniqueConstraint(columnNames = {"firstName", "lastName"})})
public class Customer extends OidBasedMutablePersistentEntity {
public static final String _FirsT_NAME = "firstName";
public static final String _LAST_NAME = "lastName";
public static final String _ORDERS = "orders";
public static final String _CONTACT_DETAILS = "contactDetails";
public static final AssociationPath CONTACT_DETAILS = new AssociationPath(
new Associationpathelement(_CONTACT_DETAILS));
@Column(nullable = false, length = 16)
private String firstName;
@Column(nullable = false, length = 16)
private String lastName;
@OnetoMany(mappedBy = "customer")
@Cascade(value = {CascadeType.SAVE_UPDATE, CascadeType.DELETE})
private List<Order> orders = new ArrayList<Order>();
@OnetoOne(optional = false)
@Cascade(value = {CascadeType.SAVE_UPDATE, CascadeType.DELETE})
private ContactDetails contactDetails;
protected List<Order> getorders() {
return orders;
}
protected void setorders(List<Order> orders) {
this.orders = orders;
}
public void addOrder(Order order) {
orders.add(order);
order.setCustomer(this);
}
public void removeOrder(Order order) {
orders.remove(order);
order.setCustomer(null);
}
public List<Order> getUnmodifiableOrderList() {
return Collections.unmodifiableList(orders);
}
// rest of the getters and setters go here
}
