Level up your Java code and explore what Spring can do for you.

The Spring Blog is a resource for developers working with the Spring Framework, providing insights, tutorials, and best practices for building enterprise Java applications. Covering a wide range of topics, including Spring Boot, Spring MVC, and Spring Data, the blog offers practical guidance on application architecture, dependency injection, and integration with other frameworks. Developers can learn how to leverage the power of Spring to create scalable, maintainable, and robust Java applications that meet the demands of modern software development.

Spring

Spring Data 2026.0.0-M1 introduces type-safe property paths as an alternative to string-based property references in queries. String-based references lack compiler validation and IDE refactoring support, causing bugs that only surface at runtime. The new approach uses Java method references (e.g., TypedPropertyPath.of(Person::getFirstName)) and Kotlin property references with operator overloads, providing compile-time validation, IDE navigation, and refactoring safety. Existing string-based APIs remain fully supported; type-safe paths are strictly additive and can be adopted incrementally. Method references are introspected once and cached for performance.
