Hibernate Envers因@Converter和AttributeConverter失败(JPA 2.1)

Question

我正在使用带有Envers的Hibernate 4.3.4和MySql 5.6.

如果没有JPA 2.1转换器,Party下面的实体就会失败Configuration.buildSessionFactory(),因为Hibernate不知道如何处理Name类:

@Entity
@Audited
public class Party
    {
    protected Name name;
    ...
    }

例外是:

org.hibernate.MappingException: 
  Could not determine type for: 
    ModuloADM.Party.Name, 
    at table: Party, for columns: [org.hibernate.mapping.Column(name)]

要解决此问题,我然后添加此转换器:

@Converter (autoApply=true)
public class NametoStringConverter
      implements AttributeConverter<Name, String>
    { ... }

现在异常变为:

org.hibernate.MappingException: 
  Could not determine type for: 
    BasicType adapter for AttributeConverter<Name,String>, 
    at table: History_Party, for columns: [org.hibernate.mapping.Column(name)]

现在,在Party实体的Envers审核表中失败了.请注意,这History_Party是审计表的名称,由选择config.setProperty("org.hibernate.envers.audit_table_prefix", "History_").

完整的堆栈跟踪是:

org.hibernate.MappingException: 
  Could not determine type for: 
    BasicType adapter for AttributeConverter<Name,String>, 
    at table: History_Party, for columns: [org.hibernate.mapping.Column(name)]

    at org.hibernate.internal.SessionFactoryImpl.<init>(SessionFactoryImpl.java:401)
    at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1857)

我该如何解决这个问题？Envers甚至与AttributeConverters兼容吗？

尝试在Party实体中使用@Convert。有时autoApply标志不起作用

@Entity
@Audited
public class Party
    {
    @Convert(converter = NametoStringConverter.class)
    protected Name name;
    ...
    }
