I use Spring Boot 3.x and an external Tomcat 10. Set up session clustering on an external Tomcat If I check on the jsp page, the session is shared, but If I check the same logic with spring boot service, the session is not being shared. If I check with jsp, it seems to be shared, so session clustering between external Tomcats is not possible. It seems like it's set up, but why can't it be shared in Spring Boot? SpringBootServletInitializer has already been implemented.
I am testing with two different Tomcat ports locally on Windows. Distributable="true" is set in Context.
@GetMapping("/session-test")
public String sessionTest(HttpSession session, Model model) {
log.info("sessionTest enter ");
String sessionId = session.getId();
Integer counter = (Integer) session.getAttribute("counter");
if (counter == null) {
counter = 1;
} else {
counter++;
}
session.setAttribute("counter", counter);
model.addAttribute("sessionId", sessionId);
model.addAttribute("counter", counter);
return "web/sessionTest";
}
Two Spring Boot servers want their sessions to be shared ...
