无法指定Elasticsearch父字段

标签： java ubuntu elasticsearch playframework

我确实遇到了Elasticsearch的问题，尤其是Elasticsearch的Java API。

我有一个运行Elasticsearch实例的Play应用程序，该实例是在相应Java API的帮助下创建的。启动应用程序后，将创建Elasticsearch索引。该索引将用于运行时期间的数据处理。当我在Mac上本地运行应用程序时（它也适用于Windows），一切运行顺利。但是，只要我在虚拟机上部署应用程序（现在是Ubuntu，虽然我也尝试使用Windows），但我面临一些奇怪的问题。应用程序启动，设置我的Elasticsearch服务器并创建索引（不正确）。现在，如果我想创建一个新文档，我收到以下错误：

为了让您更好地了解索引的结构，我附上了相关的代码段，但也想快速解释一下设置。

我的顶级实体是某种文件。映射非常简单，它有几个字段。下一个实体是“ArticleContainer”。除了一些不相关的领域，它还有一个叫做“法律”的领域。该字段包含其文档的ID。而且，我有“文章”。在其他字段中，Article具有“ArticleContainer”类型的“_ parent”字段，因此是“ArticleContainer”的子项。最后一个实体是“注释”。这个也是“文章”的孩子，因此有一个“文章”类型的字段“_parent”。

以下是创建索引的代码：

private static void createIndex() {
    client.admin().indices().prepareCreate(indexName).execute().actionGet();

    String mappingArticle = null;
    String mappingAnnotation = null;
    String mappingArticleContainer = null;
    try {
        mappingArticle = XContentFactory.jsonBuilder().startObject().startObject(Article.SC_TYPE).startObject("_parent").field("type", ArticleContainer.SC_TYPE).endObject().startObject("_routing").field("required", true).endObject().startObject("properties").startObject("ArticleContent").field("type", "string").endObject().endObject().endObject().endObject().string();
        mappingAnnotation = XContentFactory.jsonBuilder().startObject().startObject(Annotation.SC_TYPE).startObject("_parent").field("type", Article.SC_TYPE).endObject().startObject("_routing").field("required", true).endObject().startObject("properties").startObject("feature").field("type", "nested").endObject().startObject("AnnotationType").field("type", "string").field("index", "not_analyzed").endObject().startObject("Content").field("type", "string").field("index", "not_analyzed").endObject().endObject().endObject().endObject().string();
        mappingArticleContainer = XContentFactory.jsonBuilder().startObject().startObject(ArticleContainer.SC_TYPE).startObject("properties").startObject("ParentArticleContainer").field("type", "string").field("index", "not_analyzed").endObject().startObject(Law.SC_TYPE).field("type", "string").field("index", "not_analyzed").endObject().startObject(DraftedDocument.SC_TYPE).field("type", "string").field("index", "not_analyzed").endObject().startObject(Patent.SC_TYPE).field("type", "string").field("index", "not_analyzed").endObject().endObject().endObject().endObject().string();
    } catch (IOException e) {
        e.printStackTrace();
    }
    client.admin().indices().preparePutMapping(indexName).setType(Annotation.SC_TYPE).setSource(mappingAnnotation).execute().actionGet();
    client.admin().indices().preparePutMapping(indexName).setType(Article.SC_TYPE).setSource(mappingArticle).execute().actionGet();
    client.admin().indices().preparePutMapping(indexName).setType(ArticleContainer.SC_TYPE).setSource(mappingArticleContainer).execute().actionGet();
}

如前所述，奇怪的是，当我运行Play应用程序时，它在本地工作。对于VM上的生产版本，我使用

构建分发版 
play dist

并以

开头 
/var/lib/jenkins/jobs/MyApp/bin/myApp -Dhttp.port=3000 -Dhttp.address=0.0.0.0 -Dpidfile.path=/var/lib/jenkins/jobs/MyApp/myApp.pid -Dplay.crypto.secret=mysecret

我会感激任何帮助或提示！

1 个答案:

答案 0 :(得分：0)

所以这似乎是一个问题： In ElasticSearch(Nest), Can't specify parent if no parent field has been configured

现在你说

  

我有“文章”。在其他字段中，Article具有“ArticleContainer”类型的“_ parent”字段，因此是“ArticleContainer”的子项

在创建“ArticleContainer”之前，查看代码是否正在创建“文章”。如果你交换订单并在“文章”之前创建“ArticleContainer”，它应该可以正常工作。

至于在本地工作？我认为您之前可能已经创建了用于手动测试的映射，因此“重新创建”它的顺序无关紧要。

尝试删除本地计算机上的索引，然后运行程序。您可能会看到相同的错误。
