java - 如何在 Elasticsearch 中使用 Java API 在单个索引(db)中创建多个类型(表)

Question

我正在使用java api学习elasticsearch

我想使用 java api 在 elasticsearch 中创建两种或多种具有不同映射的类型。

如何在java api中的 Elasticsearch 中的同一索引中创建多个类型？

我尝试过的代码是:

创建名为“alpha”的索引。下面的工作正常。

CreateIndexResponse cr =  (ts.admin().indices().prepareCreate("alpha").setSource(*getMapping_simple().string()*, XContentType.JSON).execute().actionGet());

索引中 simple 类型的映射位于“getMapping_simple().string()”中:

 {"mappings":{"simple":{"properties":{"id":{"type":"long"},"message":{"type":"text"}}}}}

现在，在此之后我想创建一个新的映射和具有 nae 复杂的新类型

client.admin().indices().
        preparePutMapping("alpha", "complex_doc").
        setSource(*getMapping_complex().string()*, XContentType.JSON).
        execute().actionGet()

类型complex_doc(新类型)的映射:

***{"mappings":{"complex_doc":{"properties":{"id":{"type":"long"},"name":{"type":"text"},"phNo":{"type":"text"},"weight":{"type":"float"},"height":{"type":"float"}}}}}***

上面给了我一个错误

Exception in thread "main" MapperParsingException[Root mapping definition has unsupported parameters: [mappings : {complex_doc={properties={id={type=long}, name={type=text}, phNo={type=text}, weight={type=float}, height={type=float}}}}]] at

在 6.0 中，索引的多种类型已被删除!!!
