Is there any way that I could use 'countBy' prefix with my custom query in spring-data-elasticsearch?

Asked 2021-Jun-07 at 16:31

I'm now using spring-boot and spring-data-elasticsearch for my java project.

I have to count the number of users who reports some data per day, so I created a custom query for it,

Answered 2021-Jun-07 at 16:31

You can use @CountQuery instead of @Query (or add the parameter count = true to the @Query annotation) - and change the return value of the repository method to long.
This should work with query derivation and a method name like long countByUsernameAndCreatedTimeBetween(String username, Instant from, Instant two) - I have not tested this. And you would need to calculate the date parameters

I would create a custom repository fragment with a method long userWithinADay(String user) and in the implementation I would create a CriteriaQuery for the name and the dates and pass that to one of the ElasticsearchOperations.count() methods.

Edit:

@CountQuery was added in Spring Data Elasticsearch 4.2.

Spring Data Elasticsearch Class Cast exception on Named Query

...

ANSWER

Answered 2021-May-14 at 10:32

To answer your second question (Is it possible for a named query to return a SearchPage?): This is a bug that it does not work with @Query annotated methods. I fixed that yesterday for the main, 4.2.x, 4.1.x and 4.0.x branches so it will work when the next service releases are out.

To answer the first one, I will need to do some research and tests before I can say anything about that - it would be great if it would work. I think I' can give more information later this weekend.

Edit/Addition:

The query derivation from the method name is based on the properties of the Java class and is done in the Spring Data base which knows nothing about these inner fields that only exist in Elasticsearch.

But you can use the following custom repository fragment:

Name or Service not Known when calling service via spring boot in Openshift Container Platform (a cloud-based Kubernetes container platform)

I have an application which consists of a backend (spring boot) and a search engine (elasticsearch). After I deployed it into OCP, Initially I tested the connection between the two using the command "curl" to elasticsearch service (https://service-name.namespace.svc.cluster.local:9200) from backend pod and it worked. Here's the picture:

Migrating from Tomcat to Undertow org.springframework.web.servlet lib issues

I've searched Stack and google looking for an answer to no luck. So I'm hoping someone can help me here.

I have a Spring Boot API which is currently using Tomcat, now I've read about some of the performance improvements in Undertow so I wanted to give it a go and see for myself.

Now, I've removed my spring-boot-web-starter dependancy and added undertow however I'm getting the following errors in a few classes and I can't seem to find how to resolve them:

ANSWER

Answered 2021-May-03 at 15:08

By excluding spring-boot-starter-web you did exclude all its dependencies, which are necessary to run a Spring Boot project in a servlet environment. Most notably you did exclude spring-web, which contains most of the classes you find in the error messages.

As its name suggests spring-boot-starter-web isn't centered around Tomcat, only its dependency spring-boot-starter-tomcat is. So you should exclude the latter artifact and include spring-boot-starter-undertow to pull the necessary Undertow dependencies into the project:

ANSWER

Answered 2021-Apr-30 at 16:02

The problem is that you are mixing versions of the libraries which do not match and do not work together.

You define the parent as Spring Boot 2.3.5, a version which uses Spring 5.2 but later define the webflux version to 5.3.6. The Spring Data Elasticsearch version 4.1.8 also is built with Spring 5.3.2. I didn't check the recactor and netty versions in detail, but there probably is some conflict as well - it seems that in your pom you defined these dependencies with the versions from Spring Boot 2.4.5 but keep the parent version on 2.3.5.

Your application runs with the following pom (I set the parent to 2.4.5 and removed unneeded explicit dependencies):

ANSWER

Answered 2021-Apr-27 at 18:35

Spring Data Elasticsearch never closes the client as it does not create it, you create it in your configuraiton.

And like the linked document states:

you should close the high-level client when you are well and truly done with it

Spring Data Elasticsearch cannot know if and when your application does not need the connection to Elasticsearch any more.

So you might keep a reference to the client and close it if you think you really don't need it. But any calls to ElasticsearchOperations or repositories will fail after that.

Actually I never heard of a problem because of wasted resources of a single instance of this class in an application, I'd say don't bother with closing it.

QUESTION

ElasticsearchOperations query not returning exact matches

Asked 2021-Apr-02 at 01:35

I'm seriously struggling with a query in Elastic search so i'm hoping someone here can help me.

So I have an Index in elastic search which stores some basic info on a user. Then I have my Spring Boot API which allows a client to search on said index.

In my app, when a user signs up they get to choose a displayname on the site. Now when they type out a display name I want to be able to check elastic and tell them if its taken or not.

However, where I'm struggling is, say I have One user in my Index with the DisplayName of "John Boy", now user two signs up and wants the display name "Boy". When I do a search to see if "Boy" is taken, I get back "John Boy". I want it so the query tells me if "Boy" is free and not care if "John Boy" is taken.

I thought I was just getting my head around ES but maybe not, I was under the impression that the field (see index mapping below) keyword I could do a term search and get back the exact match?

Below I've included my Pojo and my ES index mapping. Please if anyone can help me....thanks for reading:
