如何使用API​​（jhipster）创建的弹性搜索实体 [英] How to Elasticsearch entities not created using API (jhipster)

问题描述

使用Jhipster与Postgresql，我创建了一个实体客户。当我使用Angular UI或POST到API向此实体添加数据时，我可以使用UI上的搜索表单搜索此数据。

但是，当我直接在数据库中插入数据时，即使在重新启动应用程序之后，数据仍然无法搜索。搜索仍然可以（仅）通过UI添加的数据。

我是弹性搜索的新手，不知道在后端插入数据并使其可用于弹性搜索之间缺少一个步骤。请帮助，如果有需要配置的东西，以便在应用程序启动期间弹性搜索从数据库中提取数据。

我的应用程序-dev.yml摘录spring数据弹性搜索：

  data：
 elasticsearch：
 cluster-name：
 cluster-nodes：
属性：
路径：
日志：target / elasticsearch / log 
数据：target / elasticsearch / data 
  

解决方案

Elasticsearch本质上是一个数据存储区，这就是JHipster与普通JPA存储库同时保存到搜索库的原因。没有内置的重建索引功能，用于在API之外进行更改。

我已经编写了一个模块，将生成一个重新索引所有实体的服务。 p>

Using Jhipster with Postgresql, I have created an entity "Customer". When I add data to this entity using the Angular UI or POST to the API, I can search this data using the search form on the UI.

However, when I insert data in the database directly, the data is not searchable even after application restart. The search would still work (only) on the data added through the UI.

I am new to elasticsearch and do not know if there is a missing step between inserting data on the backend and making it available to elasticsearch. Please help, if there is something I need to configure to let elasticsearch pick up data from the database during application startup.

My application-dev.yml excerpt for spring data elasticsearch:

    data:
    elasticsearch:
        cluster-name:
        cluster-nodes:
        properties:
            path:
              logs: target/elasticsearch/log
              data: target/elasticsearch/data

解决方案

Elasticsearch is essentially a datastore which is why JHipster saves to the search repositories at the same time as the regular JPA repositories. There is no built-in reindexing functionality for making changes to it outside of the API.

I have written a module that will generate a service for reindexing all entities.
