elasticsearch 无法在弹性搜索中整理域实例[demo.Category:7]

我已经在Grails3.3.6中实现了弹性搜索。我运行了一个应用程序，在id为7的类别上建立了错误索引

我的分类域是

class Category {

static hasMany = [events : Event]
Category parent
String name
String description
User createdBy
User modifiedBy
Timestamp createdDate
Timestamp modifiedDate

def beforeInsert(){
    createdDate = new Timestamp(new Date().getTime())
    modifiedDate = new Timestamp(new Date().getTime())
}
def beforeUpdate() {
    modifiedDate = new Timestamp(new Date().getTime())
}

static constraints = {
    name nullable: false , unique: true
    description nullable: true
    parent nullable: true
    createdBy nullable: false
    modifiedBy nullable: false
    createdDate nullable: true
    modifiedDate nullable: true
    events nullable: true
}
static searchable = true

}

package com.grailsbrains

我的事件域是

class Category {

static hasMany = [events : Event]
Category parent
String name
String description
User createdBy
User modifiedBy
Timestamp createdDate
Timestamp modifiedDate

def beforeInsert(){
    createdDate = new Timestamp(new Date().getTime())
    modifiedDate = new Timestamp(new Date().getTime())
}
def beforeUpdate() {
    modifiedDate = new Timestamp(new Date().getTime())
}

static constraints = {
    name nullable: false , unique: true
    description nullable: true
    parent nullable: true
    createdBy nullable: false
    modifiedBy nullable: false
    createdDate nullable: true
    modifiedDate nullable: true
    events nullable: true
}
static searchable = true

}

package com.grailsbrains

导入com.grailsbrains.auth.User

导入java.sql.Timestamp

班级活动{

static belongsTo = [category : Category, organization: Organization]
static hasMany = [languages : Language,formats:Format]

String title
String duration
String type
String summary
String prequel
byte[] mainVideo
byte[] mainImage
String tagline
String specialInstruction
String mapUrl
Timestamp startDateTime
Timestamp endDateTime
boolean isEnabled
boolean isExpired
String accessType
String entrance
User createdBy
User modifiedBy
Timestamp createdDate
Timestamp modifiedDate

def beforeInsert(){
    createdDate = new Timestamp(new Date().getTime())
    modifiedDate = new Timestamp(new Date().getTime())
}
def beforeUpdate() {
    modifiedDate = new Timestamp(new Date().getTime())
}

static searchable = {
    title boost: 2.0
    summary boost: 1.0
    title analyzer: 'simple'
    summary analyzer: 'simple'
    tagline analyzer: 'simple'
    category reference : true
    formats reference: true
    languages reference: true
    except = ['mainImage','mainVideo','createdBy','modifiedBy','createdDate','modifiedDate']
}

static constraints = {
    title nullable: true , unique: true
    startDateTime nullable: true
    endDateTime nullable: true
    mainImage nullable: true
    mainVideo nullable: true
    duration nullable: true
    type nullable: true, blank:false
    summary nullable: true , blank:false
    prequel nullable: true 
    tagline nullable: true 
    specialInstruction nullable: true 
    mapUrl nullable: true 
    isExpired nullable: false
    isEnabled nullable: false
    accessType nullable: true
    entrance nullable: true
    createdBy nullable: true
    modifiedBy nullable: true
    createdDate nullable: true
    modifiedDate nullable: true

}
}

我试图通过postman使用API将值插入类别表中。数据已插入表中。但我遇到此错误

2018-07-31 14:20:15.337错误---[main] g、 p.e.index.IndexRequestQueue:错误索引类 com.grailsbrains.Category（索引：com.grailsbrains\u write，类型： 第7号身份证（类别） grails.plugins.elasticsearch.exception.IndexException:未能 marshall域实例[com.grailsbrains.Category:7]位于 sun.reflect.NativeConstructorAccessorImpl.newInstance0（本机方法） 在 sun.reflect.NativeConstructorAccessorImpl.newInstance（NativeConstructorAccessorImpl.java:62） 在 sun.reflect.DelegatingConstructorAccessorImpl.newInstance（DelegatingConstructorAccessorImpl.java:45） 位于java.lang.reflect.Constructor.newInstance（Constructor.java:408）

在我的控制台里。有什么想法吗？有人能帮我吗

提前感谢。

您的ES服务器日志中有错误吗？在grails控制台中，我发现了这个错误-“未能整理域实例[com.grailsbrains.Category:7]”。在哪里可以找到ES日志？这取决于您是如何安装的。使用tarball或zip文件或通过软件包管理器？我已使用ElasticSearch日志进行了检查-没有错误。您正在运行哪个版本的ES以及哪个版本的grails ElasticSearch插件？
