Error while trying to findNearLocation with Pageable in MongoDB and Spring

Asked 2021-Jun-14 at 05:35

I'm facing a strange error when I try to execute a find near with pageable in Mongodb and spring boot. My collection have 5 stores. When I call the method with the params: Page 0 and Page Size of 5 or below it works. But when I call it with a PageSize equals or greather than the total of stores I get this error. I noticed that the error occurs when the spring data mongo calls the method doCount internally but I have no idea what is wrong.

Below is my code and the error:

You cannot access relationship properties directly via repositories. Those classes are just an encapsulation for properties on relationships and are not meant to represent a "physical" relationship or more a relationship entity. Repositories are for @Node annotated classes solely.

If you want to access and modify the properties of a relationship, you have to fetch the relationship defining entity. A relationship on its own is always represented by its start and end node.

The lately introduced required @Id is for internal purposes only. If you have a special need to persist an id-like property on the relationship, it would be just another property in the @RelationshipProperties annotated class.

You have a couple of typos in your YAML so the files aren’t equivalent. You have username and password in the properties file but data-username and data-password in the YAML.

This misconfiguration means that Hibernate cannot connect to the database to detect the dialect that it should use. As a result it required the dialect to be configured instead.

I believe you can fix the problem by correcting the YAML:

ANSWER

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.

QUESTION

Spring Batch multiple datasources and ChainedTransactionManager risks

Asked 2021-Jun-07 at 12:58

I am doing a study on the feasibility of a Spring Batch composed of two datasources. A SQL datasource for the Spring Batch metadata and a MongoDB datasource (with transactional use) for the business data. The transactional aspect raises several questions here.

The following topic: Spring batch with MongoDB and transactions and related resources provide a number of answers to my questions. The answer mentions the use of Spring's JtaTransactionManager to manage distributed transactions on the two datasources. This technique uses the 2PC protocol. It is also the most robust solution if I understood correctly. https://www.infoworld.com/article/2077963/distributed-transactions-in-spring--with-and-without-xa.html?page=2

On the other hand, I found some resources about Spring's ChainedTransactionManager. This technique uses the best effort 1PC protocol. This solution is less robust, if I understand correctly the system can be in an inconsistent state in case of a problem in the infrastructure (network failure for example). The ChainedTransactionManager has the advantage of being easier to implement and offers better performance. I saw that it is deprecated https://github.com/spring-projects/spring-data-commons/issues/2232.

What are the concrete risks of using the ChainedTransactionManager in a Spring Batch? In case of an error, can I have inconsistencies between the Spring batch metadata and the business data in Mongo? I imagine there are also considerations to take into account with retry or chunk skip strategies?

Thanks a lot for your help.

In case of an error, can I have inconsistencies between the Spring batch metadata and the business data in Mongo?

Yes, that's is the risk you should be aware of.

A common technique to avoid that is to disable state management and use the process indicator pattern. You can find an example here.

QUESTION

Is there any concept of entity state in spring data JPA similar to hibernate?

Asked 2021-Jun-04 at 10:15

Hibernate has the concept of entity state (transient, persistent, and detached). Is there a similar concept is in Spring Data JPA also?
I have gone through official Spring Data Jpa doc. This document talks about the checking of entity states but there is no discussion about how many entity state Spring Data JPA supports.

My question is: Does Spring Data JPA support multiple entity states? If yes, how many entity states are there?

...

ANSWER

Answered 2021-Jun-04 at 10:15

Spring Data JPA does not implement the persistence itself. Instead it relies on JPA and it's implementations. Hibernate is the most popular implementation.

The concept of entity lifecycle is integral part of JPA. Therefore for all intents and purposes Spring Data JPA has the exact same entity states as Hibernate/JPA, although technically Spring Data JPA has no such state because that is completely handled by the JPA implementation.

For more information about the relation between Spring Data JPA and JPA see What's the difference between JPA and Spring Data JPA? and Spring + hibernate versus Spring Data JPA: Are they different?
