kandi X-RAY | spring-data-mongodb Summary
The primary goal of the Spring Data project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services. The Spring Data MongoDB project aims to provide a familiar and consistent Spring-based programming model for new datastores while retaining store-specific features and capabilities. The Spring Data MongoDB project provides integration with the MongoDB document database. Key functional areas of Spring Data MongoDB are a POJO centric model for interacting with a MongoDB Document and easily writing a repository style data access layer.

QUESTION
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:

I'm using the following pom in my spring boot app:
...ANSWER
Answered 2021-Apr-28 at 17:08That's due to incompatible versions.
As you can see in this compatibility table, the version of Mongock you are using is compatible with spring-data 3.x, but you are using 2.x instead.
Mongock provides two drivers for spring-data, mongodb-springdata-v3-driver, for spring-data 3.x and mongodb-springdata-v2-drver for spring-data 2.2.X
I have a couple of suggestions:
- Either upgrade your spring-data dependency to 3.x, or use mongodb-springdata-v2-drver(first one recommended)
- Use dependency management so you don't need to specify the version for each dependency. You can do it for spring and for Mongock
With that you should fix your issue ;)

Answered 2021-Apr-16 at 22:26This seems to be an issue with the app. We will look into it and address it soon. In the meantime, if you want to fix it locally, try the following steps.
- Clone the repo: https://github.com/spring-cloud/stream-applications
- Change this function definition to
byteArrayTextToString|mongodbConsumer - Add the following as a dependency here.
QUESTION
How can I setup the context provider to make my SpEL extension available in a @Query("...")?
We use r2dbc with postgres.
From what I understand I would need to register my extension with a ReactiveExtensionAwareQueryMethodEvaluationContextProvider but I cannot find any documentation on how to do this. Is there a specific bean or @Configuration to use for it?
I found this unit test. It is monogo instead of r2dbc, but I think it's the same principle - however because it is a unit test it does not show how to setup the context in my normal code.
Trying to implement it like this does not provide the my() method in the SpEL
