Hibernate双向映射组件

和单向的类似，只不过多加了一个关联User关联Frofile，Profile同时也关联User

User类

import java.io.Serializable;
import com.lbx.hibernate.model.Profile;

/**
 * 组件双向关联
 * @author Administrator

 */

@SuppressWarnings("serial")
public class User implements Serializable{
	
	private int id;
	private String username;
	private String password;
	private Profile profile;
	
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public Profile getProfile() {
		return profile;
	}
	public void setProfile(Profile profile) {
		this.profile = profile;
	}
	
}

 

Profile类

import java.io.Serializable;

@SuppressWarnings("serial")
public class Profile implements Serializable{
	
	private User user;
	private String email;
	private String phone;
	private String mobile;
	private String address;
	private String postcode;
	
	public User getUser() {
		return user;
	}
	public void setUser(User user) {
		this.user = user;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	public String getPhone() {
		return phone;
	}
	public void setPhone(String phone) {
		this.phone = phone;
	}
	public String getMobile() {
		return mobile;
	}
	public void setMobile(String mobile) {
		this.mobile = mobile;
	}
	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}
	public String getPostcode() {
		return postcode;
	}
	public void setPostcode(String postcode) {
		this.postcode = postcode;
	}
	
}
