employee.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 javax.persistence.DiscriminatorColumn;
import javax.persistence.DiscriminatorValue;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Inheritance;
import javax.persistence.InheritanceType;
import javax.persistence.ManyToOne;

@Entity
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "type")
@DiscriminatorValue("0")
public class Employee {
	@Id
	@GeneratedValue
	private int id;
	private String name;

	@ManyToOne()
	private Department depart;

	@Override
	public String toString() {
		return "id=" + this.id + " name=" + this.name;
	}

	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 Department getDepart() {
		return depart;
	}

	public void setDepart(Department depart) {
		this.depart = depart;
	}
}
