这是对这个问题的跟进 Grails elasticsearch plugin with "text" mapping

我按照答案中给出的步骤进行操作，现在抛出了 NPE。另外，如果我使用 Luke 打开 lucene 索引，那么我看不到任何文档。

虽然在重新启动应用服务器时给了我以下调试消息

以下是 NPE 堆栈跟踪。域类在原始问题中给出。

如果我使用以下信息在传输模式下运行项目，那么我会收到“无可用节点错误”

elasticSearch.client.mode = 'transport'
        elasticSearch.client.hosts = [
            [host:'localhost', port:9300]
     ]
    }

如果我在帖子中添加以下内容

 static searchable = {
    except = ["user"]
comments reference:true

}

这在评论中

    static searchable = {
    except = ["user"]
    post reference:true
}

然后我得到以下 SO 异常.. 如果我只在课后这样做，那么我Property Comment.post is not mapped as [component], but broken search hit found.在运行时会出错

添加elasticSearch.unmarshallComponents = true您的Config.groovy. 应该在grails-app/conf/DefaultElasticSearch.groovy插件的文件中提供一个默认值，但不知何故它没有正确加载。

另请参阅 Github 存储库上的 issue#62

传输模式需要一个独立的 ES 实例才能在 grails 应用程序之外运行。

编辑： 关于这个问题：

属性 Comment.post 未映射为 [组件]，但发现损坏的搜索命中。

您需要在可搜索闭包中将您的关联映射为可搜索component或reference. 插件文档指出默认情况下使用可搜索的引用，但不知何故不再正确，文档有点过时了。

由于我目前不记得的原因，在以前的版本中删除了可搜索引用的默认设置，因此可能会在将来的版本中恢复默认行为......

下面的例子：

class Comment {
    Post post
    static belongsTo = [post:Post]

    static searchable = {
            post component:true
    }
}
