滚动索引（动态索引名称）在Spring Data Elasticsearch中 [英] Rolling Index (Dynamic index name) In Spring Data Elasticsearch

问题描述

我有一个usecase，其中我想根据一定的条件在单独的索引中索引我的文档。例如，我想将发票凭证存储到带有后缀的部门名称的索引。

  @Document（indexName =store_ {department}，indexStoreType =invoice）
 public class InvoiceES {
 
 // fields 
 @Id 
 private String id; 
 @Field 
私人字符串部门; 
} 
  

可以使用Spring Data来实现吗？

如果没有，是否在Spring数据的未来版本中计划？

解决方案

spring-boot-starter-data-elasticsearch-1.5，你可以通过spring el表达式来实现：

  @Bean 
部门部门（）{
 return new Department（）; 
} 
 
 @Document（indexName =store _＃{department.name（）}，indexStoreType =invoice）
 public class InvoiceES {} 
  

您可以更改bean的属性来更改要保存/搜索的索引：

  invoiceRepo.save（new Invoice（...））; 
 department.setName（newName）; 
 invoiceRepo.save（new Invoice（...））; 
  

应该注意的是不要在多线程中共享这个bean，这可能会弄乱你的索引。

I have a usecase wherein I want to index my document in a separate index based on certain condition. For example, I want to store invoice document to an index with department name suffixed with it.

@Document(indexName="store_{department}", indexStoreType="invoice")
public class InvoiceES{

    // fields
    @Id
    private String id;
    @Field
    private String department;
}

Is it possible to achieve this using Spring Data?

If not, is it planned in coming releases of Spring Data?

解决方案

As far as the spring-boot-starter-data-elasticsearch-1.5, you can achieve it by spring el expression:

@Bean
Department department() {
    return new Department();
}

@Document(indexName="store_#{department.name()}", indexStoreType="invoice")
public class InvoiceES{}

You can change the bean's property to change the index you want to save/search:

    invoiceRepo.save(new Invoice(...));
    department.setName("newName");
    invoiceRepo.save(new Invoice(...));

What should be noticed is not to share this bean in multiple thread, which may mess up your index.
