请教请教。。。！

<id
    name="id"
    type="string"
    column="id"
>
    <generator class="guid"/>
</id>

sql数据库里是uniqueidentifier
网上查查了资料说是在hibernate里这样写，

我请问下，实体类怎么写呀？？

@Id
@Generated()
@Column(name = "nav_id")
private String navId;

。。这样？？？

[shixitong]

<id name="id" type="string" unsaved-value="null" length="32">
    <column name="id" not-null="true" length="32" />
    <generator class="uuid.hex" />
</id>

一般我们都是这么写的

然后写个javabean 与之对应
那么javabean中 id 就是这样定义

private String id

[shixitong]

private String id

实体类里关于id的就这么写就可以了！

[wfcfan]

晕，得做映射啊。。

[Java技术栈]

private String id;

public setId(int id){
  this.id = id;
}

public getId(){
  return id;
}

实体类这么定义。。不知道帮到楼主没

按楼上的应该就可以了

没有一个回答正确的，哎！
