testdao:

package neron.dao.impl;  import neron.dao.testdao; import neron.models.test; import org.hibernate.session; import org.hibernate.sessionfactory; import org.springframework.beans.factory.annotation.autowired; import org.springframework.stereotype.repository;  import javax.transaction.transactional;   @transactional @repository("testdao") public class testdaoimpl implements testdao {   sessionfactory sessionfactory;  @autowired public void setsessionfactory(sessionfactory sessionfactory) {     this.sessionfactory = sessionfactory; }  private session getcurrentsession() {      return (session)sessionfactory.getcurrentsession();  }  public void save(test test) {     getcurrentsession().save(test); }  public test findbyid(int id) {     return (test) getcurrentsession().get(test.class,id); }

}

you need db update operation (insert, update, delete) within transaction boundary .

session session = getcurrentsession(); transaction trans = session.begintransaction(); //begin transaction //db operation  session.save(test) trans.commit();  //end transaction

or annotation support, in spring config bean, add this

<tx:annotation-driven transaction-manager="transactionmanager" mode="proxy" proxy-target-class="true" />

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
