关于Hibernate的主键类型:uuid

升级到3.6.0后关于UUID的警告

原来的UUIDHexGenerator已不推荐使用，应用UUIDGenerator替代。

@GenericGenerator(name="system-uuid",strategy="uuid")

改为

@GenericGenerator(name="system-uuid",strategy="org.hibernate.id.UUIDGenerator")

//---------------------------------------------------------------------
@Id
@GeneratedValue(generator = "system-uuid")   
@GenericGenerator(name = "system-uuid", strategy = "org.hibernate.id.UUIDGenerator") 
//---------------------------------------------------------------------

//---------------------------------------------------------------------
@GenericGenerator(name = "generator", strategy = "org.hibernate.id.UUIDGenerator")
@Id
@GeneratedValue(generator = "generator")
//---------------------------------------------------------------------

一些版本是:org.hibernate.id.UUIDHexGenerator

但是得看jar才知道。
