Java 8 with Spring 3.1

Question

I have recently migrated one of my service using Spring 3.1 version from JDK 1.7 to JDK 8.

Are there any known issues with using JAVA 8 lambdas with Spring 3.1 version? My service uses spring heavily for all object autowiring as well as hibernate related annotations as well.

Answer 1

Take a look at this blogpost:

Along with 4.0 M1, we’ve released Spring Framework 3.2.3, containing fixes for recently reported issues but also coming with OpenJDK 8 runtime support. Spring Framework 3.2.x will support deployment on JDK 8 runtimes for applications compiled against JDK 7 (with -target 1.7) or earlier. Note that it won’t support JDK 8’s bytecode format (-target 1.8, as needed for lambdas); please upgrade to Spring Framework 4.0 for that purpose.

So, Java 8 is supported as a runtime starting with Spring 3.2.x, but the code must be compiled against JDK 7. If you need/want to use Java 8 features, such as lambdas, etc. you will have to upgrade to Spring 4.
