public class UserAccountsCacheDataBuilder extends CacheDataBuilder
{
protected List initializeCache(HashMap params)
{
SessionInfo sessInfo = (SessionInfo)params.get(CacheConstants.OBJECT_SESSIONINFO);
String userNumber = sessInfo.userNo;
String gcif = sessInfo.sCustNo;
// Execute your logic to get the list of accounts linked to this user.
List<AccountVO> userAccounts = getUserAccountsFor(userNumber, gcif);
return userAccounts;
}

Now that we have the CacheDataBuilder ready, let us proceed to define the cache as follows:
| Code Block |
|---|
|
<Cache Id="USER_ACCOUNTS_CACHE" Scope="session">
<Handler>com.myapplication.UserAccountsCacheDataBuilder </Handler>
</Cache> |
...
| Code Block |

|
List<AccountVO> userData = CacheManager.getInstance().getDataFromCache(session, "USER_ACCOUNTS_CACHE");
for (AccountVO obj : userData)
{
//Perform your application logic here...
} |
The key aspect around Session Cache is that the data for the Session cache is stored in a key that is dynamically created in the Session. Hence, it is necessary to always pass the HttpSession object for retrieving data from this cache.
