Question

我遇到了hibernate envers的问题。我添加了eventlisteners并添加了@Audited Annotation，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。

这是构建会话等的主类。

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;
    }


}

我希望你有一个解决方案。非常感谢！

我终于更新到Hibernate 4.1.8并且问题解决了。我有错误的envers版本，似乎与我使用的hibernate版本不兼容。

Hibernate Envers不会创建修订版
