Question

我尝试使用Hibernate Envers来记录实体histroy。但失败了。

我的项目使用了Spring 3.1，JPA和Spring Data JPA（Hibenrate 4.1）。

有一个基础课。

代码：

@javax.persistence.MappedSuperclass
public abstract class BaseEntity implements Serializable {



    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", columnDefinition = "INT unsigned", nullable = false)
    @RevisionNumber
    public Long id;



    @Version
    @Column(name = "jpaversion", nullable = false, columnDefinition = "INT unsigned")
   @RevisionTimestamp
    public Long version;



    public Long getId() {
   return id;
    }



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



    public Long getVersion() {
   return version;
    }



    public void setVersion(Long version) {
   this.version = version;
    }



    @Override
    public int hashCode() {
   final int prime = 31;
   int result = 1;
   result = prime * result + ((id == null) ? 0 : id.hashCode());
   return result;
    }



    @Override
    public boolean equals(Object obj) {
   if (this == obj)
       return true;
   if (obj == null)
       return false;
   if (getClass() != obj.getClass())
       return false;
   BaseEntity other = (BaseEntity) obj;
   if (id == null) {
       if (other.id != null)
      return false;
   } else if (!id.equals(other.id))
       return false;
   return true;
    }



}

当我将@RevisionEntity添加到我的网站时。

代码：

@Entity
@RevisionEntity
@Table(name = "user", uniqueConstraints = {
    @UniqueConstraint(name = "UQ_gsmPrefix_gsmNumber", columnNames = {"gsm_prefix", "gsm_number"}),
    @UniqueConstraint(name = "UQ_email", columnNames = "email"),
    @UniqueConstraint(name = "UQ_username", columnNames = "username")})
@NamedQueries({
    @NamedQuery(name = "User.findByUsername", query = "select u from User u where u.username=:username"),
    @NamedQuery(name = "User.findByEmail", query = "select u from User u where u.email=:email")})
@Access(AccessType.FIELD)
public class User extends BaseEntity implements UserDetails, Serializable {

代码：

@Entity @Table（姓名=＆＃34;地址＆＃34;） @RevisionEntity 公共类地址扩展com.dna.bifincan.model.BaseEntity

当我将项目部署到tomcat时，我得到了这样的异常。

显然，我一起使用了@Entity和@RevisitonEntity，但它仍然会报告此信息。

我在Hibernate开发指南中阅读了相关部分的文档，似乎不需要在persistence.xml或hibernate配置中进行额外配置。是否有我在Spring项目中省略的东西。

感谢任何帮助。

为什么需要使用@RevisionEntity注释您的实体？

@RevisionEntity是一个特殊目的实体，代表修订本身。如果您想让您的实体由Envers审核，请使用@Audited注释它们。
