java - How to pre-populate data in cache with spring and ehcache? -

i have introduced ehcache in web application. working file when try populate cache after server startup. want populate cache @ time of server startup. , suggestion appreciated.

here code call ehcache on method populate cache after server started.

@transactional @cacheable(value="loadusercache") public list<usersdto> getallusers() {     list<users> users = userrepository.findall();      list<usersdto> usersdto = new arraylist<usersdto>(users.size());      (users user : users) {         usersdto userdto = mapper.map(user, usersdto.class);         usersdto.add(userdto);     }     return usersdto; } 

this code working correctly requirement want done @ time of server startup.

what try far achieve is

@cacheable(value = "loadusercache") public void update() {     list<users> users = userrepository.findall();     (users user : users) {         cachemanager.getcache("loadusercache").put(user.getid(), user);     } } 

calling method in @postconstruct annotation.
