Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
Spring Data JPA
From PHP to Java
1 project | reddit.com/r/javahelp | 10 Jun 2022
You should also consider, that Spring Boot has a lot of similarities/implementations with "J2EE, Java EE, Jakarta EE". For example "Spring Data JPA" (https://spring.io/projects/spring-data-jpa) tries to be compliant with the implmentation of the JPA specification (https://jakarta.ee/specifications/persistence/3.0/).
Amazon Aurora’s Read/Write Capability Enhancement with Apache ShardingSphere-JDBC
2 projects | dev.to | 1 Jun 2022
ShardingSphere-JDBC provides read/write splitting features and it is integrated with application programs so that the complex configuration between application programs and database clusters can be separated from application programs. Developers can manage the Shard through configuration files and combine it with ORM frameworks such as Spring JPA and Mybatis to completely separate the duplicated logic from the code, which greatly improves the ability to maintain code and reduces the coupling between code and database.
What is a simple way to read from a Oracle DataBase and write to a text file, not using Spring Batch (but using Java)? Too complicated for Spring Batch.

"Spring Batch" is not the Spring technology to access databases conveniently. That would be "Spring Data" or even "Spring Data JPA": https://spring.io/projects/spring-data-jpa
Java Spring EventSourcing and CQRS Clean Architecture microservice 👋⚡️💫

Hibernate 6 has arrived
7 projects | reddit.com/r/java | 3 Apr 2022
Be sure to check the recent Spring Boot 3.0 milestones for that. The updated Spring Data JPA 3.0 has not upgraded its build to Hibernate 6 yet as there a couple of changes in the latter that need adaption on our side, but you should be able to actually run on it already, if you tweak the dependencies to rather use the H6 artifacts. Would be awesome if you reported your findings on the ticket linked above.
Do JDBC ao Spring Data (ou: é possível reduzir código?)
2 projects | dev.to | 28 Mar 2022
Multiple Spring Boot applications in the same project
3 projects | dev.to | 5 Dec 2021
the command part is implemented via Spring Data JPA
Realistic Test Data Generation for Java Apps
3 projects | dev.to | 22 Sep 2021
The closer your test or demo data is to the real world the better you can test the application for UX, improve, and catch corner cases during development. In this article, I'll show you how to use Vaadin's example data generator to create demo data for a simple SQL database. The article shows how to build a complete app combining Spring Boot, JPA, Project Lombok, Vaadin, and MariaDB.
Jpa cant map json to entities recreating every time
1 project | reddit.com/r/javahelp | 27 Apr 2021
The rest of this might end up sounding like a rant against Spring Data JPA. For what you're doing, you need to be very aware of what's happening in the entity manager. Spring Data JPA is hiding the entity manager from you, so you have to know how a JPA repository is actually implemented to have an idea of what is going on. Your CRUD repository is going to be an instance of SimpleJpaRepository, so you can reference the Spring Data JPA source code to understand what is going on. Personally, this is exactly why I wouldn't use Spring Data JPA and its automagical CRUD repositories. Writing correct JPA code is hard enough, and if you don't know what the entity manager is doing, you will have a bad time. Spring Data JPA hiding things seems counterproductive to using JPA. Anyways...
What is the Specification Pattern
2 projects | reddit.com/r/programming | 4 Mar 2021
I have written some utility functions for composing Specifications in a nicer and safer way, inspired by how QueryDSL composes Predicates. I created a PR in attempt to merge it directly to Spring Data JPA itself (https://github.com/spring-projects/spring-data-jpa/pull/404), but unfortunately it was rejected because the Spring team plans to majorly rework Specifications in the near future (https://github.com/spring-projects/spring-data-jpa/issues/1943#issuecomment-752504333). Feel free to copy the code in my PR for your own use.
