具有“文本”映射的Grails Elasticsearch插件

Question

我有如下的域类

class Post {

    String title
    String body


    //common
    Date dateCreated
    Date lastUpdated

    //Mappings
    static belongsTo = [user:User]
    static hasMany = [comments:Comment,tags:TagBlog]

    static mapping = {
        body type:"text"
    }

    static constraints = {
        title nullable:false,blank:false
        body nullable: false, blank:false
    }
     static searchable = {
        except = 'user'

    }

}

和

class Comment {

    String comment
    int vote

    //common
    Date dateCreated
    Date lastUpdated

    static belongsTo = [post:Post,user:User]

    static mapping = { comment type:"text" }
    static constraints = {
        comment nullable:false,blank:false
        vote nullable:true,blank:true
    }
    static searchable = {
        except = 'user'

    }
}

以下是我得到的错误

| Error 2013-05-30 00:08:15,583 [elasticsearch[index]-pool-6-thread-2] ERROR index.IndexRequestQueue  - Failed bulk item: MapperParsingException[object mapping for [comment] tried to parse as object, but got EOF, has a concrete value been provided to it?]

我浏览了互联网上的许多帖子，但无法解决此问题！到目前为止，我的猜测是这可能是由于我的两个带有映射的变量造成的。type:"Text"
任何帮助将不胜感激。

我现在正在使用以下回购

mavenRepo "https://oss.sonatype.org/content/repositories/snapshots/"
        mavenRepo 'https://repo.springsource.org/libs-snapshot/'
        mavenRepo "http://maven.springframework.org/milestone/"

以下是在ES上打开它后得到的调试信息

编辑 ：

我发现了什么是原始错误：int voteES中的插件将原始类型（即，您的Comment域中的属性）映射为“对象”，但是该属性未序列化为对象，因此ES不知道如何处理。键入表决属性Integer vote将使其起作用。我已经在github仓库上提出了一个问题：https : //github.com/mstein/elasticsearch-grails-
plugin/issues/61

原始答案（增强）：

您正在使用哪个版本的插件？是从grails仓库还是直接从github仓库？无论如何，您是否可以尝试仅以神奇的方式出现在grails中央存储库中的插件的0.20.6.1-SNAPSHOT版本？

runtime ":elasticsearch:0.20.6.1-SNAPSHOT"

注意： 如果您没有使用该local模式并且正在运行自己的ElasticSearch实例，请尝试匹配grails插件的版本号：0.20.6。

另外，如果插件在使用该node模式启动期间挂起，则可能意味着它无法自动发现ES集群。在这种情况下，请尝试使用该transport模式。仅供参考，grails
ES插件将localhost:9300默认使用该地址，但这是可配置的（请参阅插件文档）。
