I am looking to create a new web application using spring boot. Unfortunately my server is fairly locked down in terms of the technology stack. It has java 5 installed on it.
Can anyone tell me whether spring boot can run on java 1.5 and what version?
thanks
Since Spring boot 1.0.0, the minimal requirement to run a Spring boot application has been Java 6. This can also be found in the reference guide of Spring boot 1.0.0:
Spring Boot can be used with “classic” Java development tools or installed as a command line tool. Regardless, you will need Java SDK v1.6 or higher.
Support for older Java versions has been dropped throughout releases, with Spring boot 1.3 moving to Java 7 as a baseline (still possible to use Java 6 with additional configuration) and Spring boot 2.x moving to Java 8 as a baseline. Additionally to what the documentation says, none of the Spring boot 1.x versions support Java 9 or higher.
Summarized:
1.0.0: Support from Java 6 - 8
1.3.0: Support from Java 7 - 8, additional configuration for Java 6 required
2.0.0: Support from Java 8 - ...
So, the answer is that it's not possible to run in Java 5.
For Spring Boot 2.0, the requirement is Java 8 as a minimum version.
From the Spring Boot 2.0 release notes :
Spring Boot 2.0 requires Java 8 as a minimum version. Many existing
APIs have been updated to take advantage of Java 8 features such as:
default methods on interfaces, functional callbacks, and new APIs such
as javax.time. If you are currently using Java 7 or earlier, you’ll
need to upgrade your JDK before you can develop Spring Boot 2.0
applications.

We have a lot of spring code written in our AEM application. We are using spring dm to run the code in osgi.
Now we would like to migrate our code to JDK 11 which requires us to migrate spring framework to 5.1 onwards. Is there a spring dm version with support springframework 5.1 onwards.
Are there any other alternative approaches to do such migration ??
regards,
We are using Javers Auditing framework [5.6.2] in our web application built on Spring boot 1.x. The directions is now to move to Spring boot 2.x and migrate to Java 11. Is there a release planned for this or is the latest current version of JaVers compatible with Java 11?
JaVers is written in Java 8. It means that you can run it safely on JVM 8 or higher (including JVM 11).
When compiled with java 7u79, spring 3.1 app is all good. When compiled on java 7u80, we're encountering some injection issues.
Searching a solution i found that Spring 3 is not compatible with java8, as explained here (due to asm).
We can see here that javac modifications were backported to java 7u80 and java 7u85.
So, am I rigth to think that it's same compatibility problem than for java 8, and that spring 3 app will not work if compiled on java7u80 ?
Sharing my experience - yes, some spring versions have problems with java 8. For example in my project we've had to change spring from 3.2.4 to 3.2.9 to use java 8. I won't put here any particular example because I don't have one but I would advice you to give spring 3.2.9 a chance. We're using it successfully with Java 8.
I want to know which version of spring is now supported from Google app engine latest stable build. i.e. Spring 4
what are its limitations ?
I have this application running on the AppEngine that uses Spring 4.x.
What version of Java do you need to be able to use Spring 3.1.1. The geeks of Spring never put down in their documentation clearly what version is needed. Someone please help.

Java SE and Java EE Support
The Spring Framework is now based on Java 5, and Java 6 is fully supported.
Furthermore, Spring is compatible with J2EE 1.4 and Java EE 5, while at the same time introducing some early support for Java EE 6.
