hibernate單一實體的級聯查詢

其實單一實體的一對多和多對一和2個實體的用法是一樣的，現在以user為例：

 

java程式碼：

 

package com.test.bean;

 

package com.test.bean; .util.Set;

public class User
{
 private Integer id;
 private String firstname;
 private String lastname;private private User user;

 

 public Set getChildrens() {

  return childrens;

 }

 public void setChildrens(Set childrens) {

  this.childrens = setChildrens(Set childrens) {

  this.childrens = user;
 }

 public void setUser(User user) {

  this.user = user;
 }

 public Integer getId()

 {
  return id;
 }

 public String getFirstname()
 {
  return firstname;
 }

 public void setFirstname(String firstname)

 public void setFirstname(String firstname)

 public void setFirstname(String firstname) f String getLastname()

 {
  return lastname;
 }

 public void setLastname(String lastname)

 {
  this.lastname = lastname;
 }

 public int getAge()

 }

 public int getAge()
 {

樣)

 {
  this.age = age;
 }

 public Integer getParentID() {

  return parentID;
 }

 public void setParentID(Integer parentID) {

 public void setParentID(Integer parentID) {
