我对休眠环境有疑问。我添加了事件监听器并添加了@Audited 注释,但是当我更改名称(或其他任何内容)时,创建的数据库中没有任何修订。我希望你能帮助我。
这是我建立会话等的主类。
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
public class Main {
public static void main(String[] args) {
new Main();
}
public Main() {
Configuration configuration = new Configuration().configure();
ServiceRegistryBuilder registry = new ServiceRegistryBuilder();
registry.applySettings(configuration.getProperties());
ServiceRegistry serviceRegistry = registry.buildServiceRegistry();
SessionFactory sessionFactory = configuration
.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();
Address address1 = new Address();
address1.setStreetName("Privet Drive");
address1.setHouseNumber(4);
Person person1 = new Person();
person1.setName("Hi");
person1.setSurname("test");
person1.setAddress(address1);
session.beginTransaction();
session.persist(person1);
session.persist(address1);
session.getTransaction().commit();
person1.setName("Hans");
session.beginTransaction();
session.persist(person1);
session.persist(address1);
session.getTransaction().commit();
session.close();
}
}
这里是 Person 类:
package Main;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
import org.hibernate.envers.Audited;
import org.hibernate.envers.RevisionEntity;
import org.hibernate.envers.RevisionNumber;
import org.hibernate.envers.RevisionTimestamp;
@Entity
@Table(name="PERSON")
@Audited
public class Person{
@Id
@GeneratedValue
@RevisionNumber
private int id;
private String name;
private String surname;
private String username;
@ManyToOne
private Address address;
public int getId() {
return id;
}
public String getName() {
return name;
}
public String getSurname() {
return surname;
}
public Address getAddress() {
return address;
}
public void setId(int id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
public void setSurname(String surname) {
this.surname = surname;
}
public void setAddress(Address address) {
this.address = address;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
地址:
package Main;
import java.util.Set;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;
import org.hibernate.envers.Audited;
@Entity
@Table(name="ADDRESS")
@Audited
public class Address {
@Id
@GeneratedValue
private int id;
private String streetName;
private Integer houseNumber;
private Integer flatNumber;
@OneToMany(mappedBy = "address")
private Set<Person> persons;
public int getId() {
return id;
}
public String getStreetName() {
return streetName;
}
public Integer getHouseNumber() {
return houseNumber;
}
public Integer getFlatNumber() {
return flatNumber;
}
public Set<Person> getPersons() {
return persons;
}
public void setId(int id) {
this.id = id;
}
public void setStreetName(String streetName) {
this.streetName = streetName;
}
public void setHouseNumber(Integer houseNumber) {
this.houseNumber = houseNumber;
}
public void setFlatNumber(Integer flatNumber) {
this.flatNumber = flatNumber;
}
public void setPersons(Set<Person> persons) {
this.persons = persons;
}
}
还有我的 hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>

我希望你有我的解决方案。非常感谢!
