openshift - Upgrading to Spring 4 -

-

i have spring 3 app deployed in openshift jboss eap6, , want upgrade ver 4. want upgrade java8. has here been successful in doing so? things must considered? how can make transition easier? i'm afraid of jar hell.

solution question

  1. don't worry spring 4 100% compatible java 8
  2. for jars need use bill of materials of spring 4 jars can obtained in link. use only these jars take care of dependencies issues.
  3. typically replace these jar files in web applications , try build , deploy application. got jar upgrade if runs without issues. 100% run without issues.
  4. then depending scenarios can apply spring-framework components.
