Hibernate 如何将ID映射到Grails中的不同列？

当我在域类中有ID时，它工作得很好

class Book {
    int id
    String bookAuthor

    static constraints = {
        bookAuthor blank: false, maxSize:30
    }

    static mapping = {    
        version false
        id generator: 'sequence',
        params: [sequence:'s_book_seq']
    }
}

但有一次我试着把Id映射到BookId

class Book {
    int bookId
    String bookAuthor

    static constraints = {
        bookAuthor blank: false, maxSize:30         
    }

    static mapping = {
        version false
        id generator: 'sequence',
        params: [sequence:'s_book_seq'], column :'bookId'
    }
}

那么Grails将无法启动我的应用程序。如何将ID映射到其他字段？ 我得到的

错误是：

更新：

moise2022的解决方案奏效了。我可以打开列表页。但是，在show页面中生成的${bookInstance}是错误的

<g:link class="edit" action="edit" resource="${bookInstance}"><g:message code="default.button.edit.label" default="Edit" /></g:link>



而不是

<a href="/gTunes/book/edit/1" class="edit">Edit</a>



它产生

<a href="/gTunes/book/edit" class="edit">Edit</a>



所以编辑导航坏了

更新：

删除
我试图改变

<g:form url="[resource:bookInstance, action:'delete' ]" method="DELETE">



到



那仍然不起作用

使用name参数从默认id更改名称

static mapping = {
    id generator: 'sequence',
    params: [sequence:'s_book_seq'], 
    name: 'bookId'
}

检查文档并阅读此
@johnsam我想因为您没有使用默认的
id
name grails不知道使用什么id。你必须告诉它身份证是什么<代码>

谢谢，我也明白了。但仍然无法使删除生效。查看我的更新。我猜您的控制器中有一个名为“删除”的操作。如果是这样，您可以尝试使用

删除记录，不需要发回整个对象。此外，[g:form][1]文档可能会有帮助[1]是。我明白了。但我无法找出正确的语法来实现这一点。gsp代码是由generate forms命令生成的。我认为有必要对g:formurl属性进行一些调整，但不确定如何调整。

static mapping = {
    id generator: 'sequence',
    params: [sequence:'s_book_seq'], 
    name: 'bookId'
}
