Write some Software

i need you to create Generic DAO Hibernate class. see link: [login to view URL] i need full example. You should use Spring, Hibernate, MySQL. For example: i want below UserDao to extend from Generci DAO. Generic DAO should handle CRUD functionality and custom UserDao should handle rest. @Transactional(value="myTransactionManager") public class UserDao { @Qualifier("mySessionFactory") public SessionFactoryImpl sessionFactory; public void setSessionFactory(SessionFactoryImpl sessionFactory) { [login to view URL] = sessionFactory; } public UserEntity getUser(int userId) { UserEntity user = (UserEntity) [login to view URL]().get([login to view URL], userId); return user; } public UserEntity getUser(String email) { Query query = [login to view URL]().createQuery( "from UserEntity where email='" + email + "' "); List<UserEntity> userList = [login to view URL](); UserEntity user = (UserEntity) [login to view URL](0); return user; } public List<UserEntity> getUsers() { Query query = [login to view URL]().createQuery( "from UserEntity "); List<UserEntity> userList = [login to view URL](); return userList; } public List<UserEntity> getUsers(int groupId) { Query query = [login to view URL]().createQuery( "from UserEntity WHERE group_id='" + groupId + "' "); List<UserEntity> userList = [login to view URL](); return userList; } public List<UserEntity> getUsers(int groupId,int roleId) { Query query = [login to view URL]().createQuery( "from UserEntity WHERE group_id='" + groupId + "' AND (role_id='" + roleId + "' OR role_id='3')"); List<UserEntity> userList = [login to view URL](); return userList; } public void updaetUser(UserEntity userEntity) { [login to view URL]().update(userEntity); } public void deleteUser(UserEntity userEntity) { [login to view URL]().delete(userEntity); } public void saveUser(UserEntity userEntity) { [login to view URL]().save(userEntity); } }
