Grails 中的休眠环境答案

【问题描述】：

我想在我的 Grails (v3.0.11) 应用程序中使用 Hibernate Envers。由于 grails envers 插件已经死了，我试着自己做。

我做了什么：

在 build.gradle 中，我添加了 Hibernate Envers 依赖项 compile "org.hibernate:hibernate-envers"

我的域名如下：

import org.hibernate.envers.Audited

@Audited
class Hotel {
    String name
}

在脚手架的Controller中，我只改了：

class HotelController {

    ...

    @Transactional
    def save(Hotel hotel) {
        ...
        Hotel.withTransaction {
            hotel.save flush:true    
        }
        ...
    }

    ...

}

保存时出现以下异常：

URI
    /hotel/save
Class
    org.hibernate.envers.exception.AuditException
Message
    null

我做错了什么？如何使交易“活跃”？

【问题讨论】：

看起来您实际上在那里使用了两个事务。尝试删除 withTransaction 闭包或 @Transactional 注释。看看范围内只有一个事务会发生什么。
我都试过了，没有任何改变。我只是尝试使用 withTransaction 方法，因为我在旧的 envers 插件 (lucasward.net/2011/04/grails-envers-plugin.html) 中看到过它

标签： hibernate grails hibernate-envers

【解决方案1】：

尝试排除 envers 的传递依赖。为我工作。我想拉入hibernate-entitymanager 在这里没有任何好处。所以：

compile("org.hibernate:hibernate-envers") { transitive = false }
