2.0.0

🚀 Release v2.0.0

📅 Release Date: February 18, 2025

🎉 This major release introduces powerful enhancements for dynamic querying in Spring Data JPA while simplifying the API.

✨ New Features

• Projection Interface Support

  • You can now map query results directly to DTOs or interfaces without additional conversions.
  • Example:

    @RestController
    @RequestMapping("/users")
    public class UserController {
        @Autowired
        private ProjectionFactory projectionFactory;
    
        @Autowired
        private UserRepository userRepository;
    
        @PostMapping("/search")
        public List<UserMinimalDto> getAllMinimal() {
            return projectionFactory.create(User.class, UserMinimalDto.class).findAll();
        }
    }

    ✅ Cleaner & more efficient than manual DTO conversion, and more powerful then Spring's original projection mechanism.

• Refactored Query API 🚀

  • Removed executeQuery method as it can be found confusing.
  • Added Query<T> get(Specification<T> specification); which supports building on existing Specification objects.

🔥 Breaking Changes

• Removed executeQuery Method
  • The executeQuery method has been removed in favor of Projection interface which contains all the necessary methods to replace the executeQuery method.

⚡ Upgrade Guide

1. Maven Dependency Update

• Update your pom.xml to use the latest version:

  <dependency>
    <groupId>dev.rosemarylab.dataquerying</groupId>
    <artifactId>DataQuerying</artifactId>
    <version>2.0.0</version>
</dependency>

2. Replace executeQuery calls

• Switch to Projections for specifying the entity type, return type, and optionally filter data with or without pagination.

  Query<User> query = Query.where("name", "John");   
  return projectionFactory.create(User.class, UserMinimalDto.class).findAll(query.buildSpecification());
