hibernate2升级到hibernate3的报错问题 急。。。

[yinlei109]

架构是struts+spring+hibernate
现在是hibernate2想升级到hibernate3
更新了相关的jar包和引用的地方，现在启动的时候报错
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'monthPlanService' defined in ServletContext resource

请高手给指点一下

我也被这个问题困扰。hibernate的配置文件看起来又没什么问题，但总提示主键生成出错，产生不了bean

spring里的hibernate包换成3了吗

[yinlei109]

求 高手 指点 。。。。

[Quote=引用 6 楼 Landor2004 的回复:]
<id name="id" type="java.lang.String" column="id">
<generator class="uuid.hex" />
</id>

改成assigned，自定义主键试一下，如果你的包真是3的话，就不会有问题

那个。。。我喜欢用native，可以根据需要在3个里面选一个，哪三个我忘记了。。。汗

[Landor2004]

<generator class="uuid"/>

[pengj58]

spring里面的hibernate包已经换成3了。
换成<generator class="uuid"/>还是同样报错

[Landor2004]

<id name="id" type="java.lang.String" column="id">
<generator class="uuid.hex" />
</id>
