具有 "text"映射的 Grails elasticsearch 插件

Question

我有如下所示的域类

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'

    }
}

下面是我得到的错误

| 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?]

我在网上看了很多帖子，但我无法解决这个问题!!到目前为止，我的猜测是这可能是由于我的两个变量映射 type:"Text"非常感谢任何帮助。

我现在正在使用以下 repo 协议(protocol)

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

下面是ES开启后得到的调试信息

编辑:

我发现了最初的错误是什么:原始类型(即:评论域中的 int vote 属性)被 ES 中的插件映射为“对象”，但是属性没有序列化为对象，所以 ES 不知道如何处理它。将 vote 属性键入 Integer vote 将使它起作用。我已经在 github 存储库中为此提交了一个问题:https://github.com/mstein/elasticsearch-grails-plugin/issues/61

原始答案(增强):

您使用的是什么版本的插件？是来自 grails 存储库还是直接来自 github 存储库？无论如何，您能否尝试拉取刚刚神奇地出现在 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:如果您没有使用本地模式并且有您自己的ElasticSearch实例在运行，请尝试匹配grails插件的版本号:0.20 .6。

另外，如果插件在使用node模式启动的过程中挂掉了，这可能意味着它没有自动发现ES集群。在这种情况下，请尝试改用 transport 模式。仅供引用，grails ES 插件默认使用地址 localhost:9300，但这是可配置的(请参阅插件文档)。
