我刚把我的项目的hibernate版本升级到了5.0.0.FINAL。但是我发现我收到了这个警告。我想摆脱它。我不知道它是否会影响我的应用程序。
2015-08-24 14:29:22.235 WARN --- [ main] org.hibernate.orm.deprecation : HHH90000003: Use of DOM4J entity-mode is considered deprecated
由于我从未显式使用实体模式，所以我在网上搜索了一下，但几乎没有关于它的信息。这是EntityMode枚举。由于不再有DOM4J模式，我怀疑如果我继续在5.0.0版本中使用hibernate，可能会在生产中出现错误。
我还在使用hibernate的envers。如果我禁用envers，警告也会消失。我同时使用spring和hibernate和envers。以下是它们的版本。
<spring.version>4.2.0.RELEASE</spring.version>
<hibernate.version>5.0.0.Final</hibernate.version>
<hibernate.envers.version>5.0.0.Final</hibernate.envers.version>
<hibernate-jpa-2.1-api.version>1.0.0.Final</hibernate-jpa-2.1-api.version>
<project.java.version>1.8</project.java.version>
这是我的hibernate-jpa配置。

这里是一个实体的例子。
@Entity
@Table(name = "T_USER")
@Access(AccessType.FIELD)
@Audited
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(name = "C_USERNAME", unique = true)
private String username;
@Column(name = "C_PASSWORD")
private String password;
@Column(name = "C_EMAIL")
private String email;
// Getters && Setters etc
}
更新
我在github上创建了一个项目，展示了这种行为。经过一些调试，我发现警告信息是在ModelBinder#L2441上创建的。
以下是示例代码:
public class ModelBinder
...
private void bindProperty(
MappingDocument mappingDocument,
AttributeSource propertySource,
Property property) {
property.setName( propertySource.getName() );
if ( StringHelper.isNotEmpty( propertySource.getName() ) ) {
// Here is the line that print outs the log I was mentioned
DeprecationLogger.DEPRECATION_LOGGER.logDeprecationOfDomEntityModeSupport();
}
...
}
}
当我查看
mappingDocument.getOrigin()的值时，它是Origin(name=envers,type=OTHER)。因此，我仍然怀疑envers引起了这个警告。顺便说一下，如果您删除
@Audit注释或使用我提到的属性，则此警告仍将消失。
POJO模式。但是你可以通过@Tuplizer注释或<tuplizer />标签来覆盖它。但是由Envers创建的实体默认使用DOM。我在日志中看到与Envers实体大小相同数量的警告。但是我无法覆盖Envers实体模式。您可以在hibernate文档中找到有关tupilizer的额外信息。 - bhdrkn
