department.java

主要是Hibernate的一些源代码。从一开始的使用到最后的一些程序例子

package cn.itcast.jpa.domain;

import java.util.Set;

import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;

@Entity
public class Department {
	@Id
	@GeneratedValue
	private int id;
	private String name;

	@OneToMany(targetEntity = Employee.class, cascade = { CascadeType.MERGE,
			CascadeType.PERSIST }, fetch = FetchType.LAZY, mappedBy = "depart")
	private Set<Employee> emps;

	// private List<Employee> emps;

	// private Map<String, Employee> emps;

	// private Employee[] emps;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public Set<Employee> getEmps() {
		return emps;
	}

	public void setEmps(Set<Employee> emps) {
		this.emps = emps;
	}
}
