spring - Struts2 and Hibernate - Access ActionContext.getContext().getSession() outside a Servlet -
i try access actioncontext.getcontext() outside struts (struts2) action in 2 different situations , different result, regarding trying:
- from currenttenantidentifierresolverimpl (my) implementation of currenttenantidentifierresolver, hibernate interface --> ko (the result null)
- from abstractroutingdatasource (my) implementation of abstractdatasource, spring interface --> ok
i have found solution currenttenantidentifierresolverimpl working using threadlocal, :
- why working spring , not hibernate?
- why can't access actioncontext (threadlocal also) can access threadlocal (that set actioncontext, same place, same data)?
currenttenantidentifierresolverimpl : supposed give tenant used hibernate can give connection database.
import java.util.map; import org.hibernate.context.spi.currenttenantidentifierresolver; import com.opensymphony.xwork2.actioncontext; public class currenttenantidentifierresolverimpl implements currenttenantidentifierresolver { @override public string resolvecurrenttenantidentifier() { if (actioncontext.getcontext() != null) { abstractroutingdatasource : same handled spring
import java.util.map; import org.springframework.jdbc.datasource.lookup.abstractroutingdatasource; import com.opensymphony.xwork2.actioncontext; public class routingdatasource extends abstractroutingdatasource { @override protected object determinecurrentlookupkey() { if (actioncontext.getcontext() != null) { when have @ stack in both case, can see that:
- abstractroutingdatasource has got servlet (homeaction) in stack
- currenttenantidentifierresolver not have servlet (homeaction) in stack
here stack traces.

the actioncontext seems initialized filter "strutsprepareandexecutefilter":
dofilter(servletrequest req, servletresponse res, filterchain chain) throws ioexception, servletexception { httpservletrequest request = (httpservletrequest) req; httpservletresponse response = (httpservletresponse) res; try { prepare.setencodingandlocale(request, response); prepare.createactioncontext(request, response); and in "hibernate" case filter not executed (cf. stack traces in question) ==> actioncontext not initialized.
so conclusion: yes can access actioncontext outside servlet, if stack "classic". careful if try access framework or transversal code.
here solution hibernate problem: have created own filter access httpsession (we have access here) , put information need in threadlocal.
my filter:
public class tenantidentifierfilter extends onceperrequestfilter { @override protected void dofilterinternal( httpservletrequest request, httpservletresponse response, filterchain filterchain) throws servletexception, ioexception { httpsession session = request.getsession(); string tenantcode = (string) session.getattribute(worksession.connected_entity); usertenantcontext.set(tenantcode); logger.debug("vpd-multitenancy - tenantcode : " + tenantcode); filterchain.dofilter(request, response); } } my threadlocal:
public class usertenantcontext { public static final threadlocal<string> usertenantcode = new threadlocal<string>(); /** * set user in context of threadlocal * @param user */ public static void set(string tenantcode) { usertenantcode.set(tenantcode); } public static void unset() { usertenantcode.remove(); } /** * @return user in context of threadlocal */ public static string get() { return usertenantcode.get(); } } my web.xml (be sure put filter before hibernate filter, threadlocal initialized):
... <filter-mapping> <filter-name>characterencodingfilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- vpd-multitenancy-add--> <filter> <filter-name>tenantfilter</filter-name> <filter-class> amundi.sits.mgs.web.services.user.tenantidentifierfilter </filter-class> </filter> <filter-mapping> <filter-name>tenantfilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- vpd-multitenancy-add/ --> <filter> <filter-name>hibernatefilter</filter-name> <filter-class> org.springframework.orm.hibernate4.support.opensessioninviewfilter </filter-class> </filter> <filter-mapping> <filter-name>hibernatefilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> ...
