Spring Data Elasticsearch @Document indexName 在运行时定义 [英] Spring Data Elasticsearch @Document indexName defined at runtime

问题描述

是否可以(在运行时)为每个 @Document 动态指定 indexName，例如，通过配置文件?或者是否可以使 @Document 依赖 Spring 环境(dev、prod)?

Is it possible to specify dynamically (at runtime) the indexName for each @Document, for example, via a configuration file? Or is it possible to make @Document Spring environment (dev, prod) dependant?

谢谢！

推荐答案

@Document 注解不允许直接在参数中传递索引名.不过我找到了解决方法.

The @Document annotation does not permit to pass the indexname in parameter directly. However I found a work around.

在我的配置类中，我创建了一个返回字符串的 Bean.在这个字符串中，我用 @Value 注入了索引的名称:

In my configuration class I created a Bean returning a string. In this string I injected the name of the index with @Value :

@Value("${etrali.indexname}")
private String indexName;

@Bean
public String indexName(){
    return indexName;
}

之后可以像这样将索引注入@Documentation 注解:

Afterward it is possible to inject the index into the @Documentation annotation like this :

@Document(indexName="#{@indexName}",type = "syslog_watcher")

对我有用，希望对你有帮助.

It works for me, I hope it will help you.
