Hibernate Spring Webflow一对多复制主键

Question

我已经在这方面工作了一段时间，似乎无法弄清楚，除了在某些时候它按预期工作。我有两个对象，一个可以与多个地址关联的用户。保存新用户和地址一起工作正常，但当我尝试向现有用户添加新地址时，我收到有关用户表的重复主键的错误。我想这与hibernate中的配置有关，尝试单向和双向。

以下是任何相关文件。谢谢你的帮助！

调用方法

的部分流程

<view-state id="newAddress" model="address">
        <transition on="addNewAddress" to="customerReady" />
        <on-exit>
            <evaluate expression="address.street1 = requestParameters.street1"></evaluate>
            <evaluate expression="address.street2 = requestParameters.street2"></evaluate>
            <evaluate expression="address.apt = requestParameters.apt"></evaluate>
            <evaluate expression="address.city = requestParameters.city"></evaluate>
            <evaluate expression="address.special = requestParameters.special"></evaluate>
            <evaluate expression="address.city = requestParameters.city"></evaluate>
            <evaluate expression="address.state = 'NY'"></evaluate>
            <evaluate expression="user.addAddress(address)"></evaluate>
            <evaluate expression="usersService.update(user)"></evaluate>
        </on-exit>
    </view-state>

userService.update（user）将您发送到dao

public void update(Users users) {
        session().saveOrUpdate(users);
    }
