hibernate java

package model;

import java.io.Serializable;

public class User implements Serializable {

private static final long serialVersionUID = 1L;

private Integer id;
private String username;
private String password;
private Profile profile;

public User(){

}

public Integer getId() {
return id;
}

public void setId(Integer 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;
}

public void addProfile(Profile profile){
  profile.setUser(this);
  this.setProfile(profile);
}

}

User.hbm.xml如下:

package model;

import java.io.Serializable;

public class Profile implements Serializable {

private static final long serialVersionUID = -7010557039785604098L;

private Integer id;
private String email;
private String address;
private String postcode;
private String mobile;
private String phone;
private User user;

public Profile(){

}

public Integer getId() {
return id;
}

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

public String getEmail() {
return email;
}

public void setEmail(String email) {
this.email = email;
}

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;
}

public String getMobile() {
return mobile;
}

public void setMobile(String mobile) {
this.mobile = mobile;
}

public String getPhone() {
return phone;
}

public void setPhone(String phone) {
this.phone = phone;
}

public User getUser() {
return user;
}

public void setUser(User user) {
this.user = user;
}
