在 Grails 和 ElasticSearch 中解组 属性 失败

Question

我正在使用 Grails 2.5.0 和 ElasticSearch 0.0.4.6！我有以下域名 类:

Class Library {
    --- code omitted ---
    static hasMany = [books:Book]
    static searchable = true
    --- code omitted ---
}

Class Book {
    --- code omitted ---
    static belongsTo = [library:Library]
    static searchable = true
    --- code omitted ---
}

我试着搜索这样的书：

--- code omitted ---
def events = elasticSearchService.search(
            {
                query_string(fields: ["Name"],
                        query: query)
                suggest : { suggest_mode: 'popular' }
            })

    render events as JSON

我收到以下错误：

ERROR unmarshall.DomainClassUnmarshaller - Error unmarshalling property 'library' of Class Book with id 2 Message: Property Book.library is not mapped as [component], but broken search hit found.

Answer 1

您需要将 Book 域的 'library' 属性 设置为组件。

在您的图书域中替换您的以下代码

static searchable = true

和

static searchable = { library component: true }
