Hibernate EntityInterceptor没有拦截

Question

我正在使用Spring，Hibernate和Struts开发一个Web应用程序。对于我的域实体类，我有2个java.util.Date变量，我想使用Hibernate Interceptor设置。

每个实体类都有以下2个我想设置的变量。

private Date createDate; private Date updateDate;

我编写了代码并完成了所需的配置，不知怎的，实体永远不会被截获。拦截器使用Spring注入SessionFactory。我在AuditInterceptor类上添加了断点。他们从未被援引过。代码和配置如下。非常感谢任何帮助。

@Entity  
  @Table(name = "person")  
  public class Person {  
    @Id  
    @GeneratedValue
    private Long id;
    @Column(name = "create_date", nullable = false)
    private Date createDate;  
    @Column(name = "update_date", nullable = false)  
    private Date updateDate;  
    @Column(name = "version_number")  
    @Version  
    private int versionNumber;  
    // getters and setters      
  }

public class AuditInterceptor extends EmptyInterceptor {    
    public boolean onFlushDirty(Object entity, Serializable id,  
            Object[] currentState, Object[] previousState,  
            String[] propertyNames, Type[] types) throws CallbackException{  
        setValue(currentState, propertyNames, "updateDate", new Date());  
        return true;  
    }  
    public boolean onSave(Object entity, Serializable id, Object[] state,  
            String[] propertyNames, Type[] types) throws CallbackException{  
        setValue(state, propertyNames, "createDate", new Date());  
        setValue(state, propertyNames, "updateDate", new Date());  
        return true;  
    }  
    private void setValue(Object[] state, String[] propertyNames,  
            String propertyToSet, Object value) {  
        int index = Arrays.asList(propertyNames).indexOf(propertyToSet);  
        if (index >= 0) {  
            state[index] = value;  
        }  
    }  
}
