At compilation time, the source model is introspected and JPA entities and Spring Components are flagged.

This support has been added to shortcut the candidate component identification step in the classpath scanner.Īn application build task can define its own META-INF/ponents file for the current project. Spring Framework 5.0 now supports candidate component index as an alternative to classpath scanning. Also, this new version will auto detect Log4j 2.x, SLF4J, JUL ( ) without any extra bridges.ĭefensive programming also gets a thrust with the Resource abstraction providing the isFile indicator for the getFile method. On the logging front, Spring Framework 5.0 comes out of the box with Commons Logging bridge module, named spring-jcl instead of the standard Commons Logging. This enables dealing null values at compile time rather than throwing NullPointerExceptions at runtime. and annotations to explicitly mark nullable arguments and return values.Core Spring interfaces now provide selective declarations built on Java 8 default methods.Based on Java 8 reflection enhancements, method parameters in Spring Framework 5.0 can be efficiently accessed.The core Spring Framework 5.0 has been revised to utilize the new features introduced in Java 8. However, when Java 9 is released ( expected in September of 2017), Spring Framework 5.0 will be ready. However, with the Java 9 release running 18 months + behind, the Spring team decided to decouple the Spring Framework 5.0 release from Java 9. Originally, Spring Framework 5.0 was expected to release on Java 9. The framework now requires a minimum of Java 8. The framework itself was carrying a lot of baggage in supporting deprecated Java releases. While as developers, we’ve been able to enjoy all the new features found in modern Java releases. This is actually very significant for the framework. Therefore, Java 8 is the minimum requirement to work on Spring Framework 5.0. The entire Spring framework 5.0 codebase runs on Java 8. JDK Baseline Update for Spring Framework 5.0 I’m excited about the new features and enhancements in Spring Framework 5.0.Īt a high level, features of Spring Framework 5.0 can be categorized into: This is expected to be the final release on the roadmap to the first GA (General Availability) release of Spring Framework 5.0. Now, a year later, we are looking forward to Release Candidate 3 (RC3) to be released on July 18th, 2017. Juergen Hoeller, Spring Framework project lead announced the release of the first Spring Framework 5.0 milestone (5.0 M1) on 28 July 2016. Spring Framework 5.0 is the first major release of the Spring Framework since version 4 was released in December of 2013.
