Thanks Mark. Just tried that. I put the redisson-tomcat jar outside of
WEB-INF/lib and added it with scope provided. I get the exact same issue.
What am I doing wrong?
Here's my code:
HttpSession session = httpServletRequest.getSession(false);
try {
RedissonSessionManager rsm = (RedissonSessionManager) getManager(session);
} catch (Exception e) {
e.printStackTrace();
}
private Manager getManager(HttpSession session) throws Exception {
Field facadeSessionField =
StandardSessionFacade.class.getDeclaredField("session");
facadeSessionField.setAccessible(true);
StandardSession stdSession = (StandardSession)
facadeSessionField.get(session);
return stdSession.getManager();
}
