Over the past year, we have significantly improved the cache abstraction, with support of JSR-107 (JCache) annotations and a better declarative model to share or externalize common settings. In Spring Boot 1.3, we now offer a comprehensive auto-configuration for it.

In a nutshell, the cache abstraction applies caching to methods, thus reducing the number of executions based on the information available in the cache. The caching logic is applied transparently: the method below will only be invoked if the specified ISBN is not already present in the books cache. Upon calling that method for a missing Book, the caches will be updated transparently so that a further call does not invoke the…

As of Spring Framework 4.0, Java 8 is supported as a first-class citizen and we've seen some confusion in the Spring community since then. How do we manage to support Java 8 and remain compatible with Java 6 and Java 7 after all? This blog post provides some insight into how we're handling this within the framework codebase.

Java 8 language features vs. Java 8 APIs

First, a distinction must be made between using new language features and new APIs in a given Java generation such as Java 8. If a class uses a Java 8 language feature such as a lambda expression, it has to be compiled with -source 1.8 -target 1.8 and therefore the whole compilation unit will only work on Java 8+. However, if a particular class in a library optionally uses a new Java 8 interface such as java.util.stream.Stream, the library can still run on a previous Java generation as long as it is being compiled with e.g. -source 1.6 -target 1.6 - and as long as the use of that particular …

Stay tuned for 4.2 RC1, coming up in May!

Application events are available since the very beginning of the Spring framework as a mean for loosely coupled components to exchange information. One of the most well known usage of application events is the following:

@Component
public class MyListener 
        implements ApplicationListener<ContextRefreshedEvent> {
  
    public void onApplicationEvent(ContextRefreshedEvent event) {
        ...
    }
}

This allows MyListener to be notified when the context has refreshed and one can use that to run arbitrary code when the application context has fully started.

On behalf of the team I am pleased to announce the immediate availability of Spring Framework 4.1.3.

Spring Framework 4.1.3 is our third maintenance release in the 4.1.x line and comes with over 50 fixes and improvements.

We are still planning on another release later this month (4.1.4) at which point 4.1.x will turn into a maintenance branch, with active development on 4.2 happening on…
