Cache auto-configuration in Spring Boot 1.3

Engineering | June 15, 2015 | ...

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…

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…
