sessionfactory

问题 Good afternoon, I have been stuck on this issue for a number of days now and I don't feel my understanding of Nhibernate / SQL Server is of enough so that I might figure it out. The issue is that any unit test that involves making a call to: Nhibernate.Cfg.Configuaration.BuildSessionFactory(); Just becomes stuck in a running state, I am forced to press 'Stop' in order to get NUnit to respond. At which point an error dialogue appears with the following information: "No connection could be made

问题 I'm working on an intranet MVC web application, using Fluent NHibernate. As everyone knows, creating the necessary ISessionFactory is heavy, and therefore should be done only once. Hence, I create it in the Global.asax file during Application_Start , then cache it in the application for future use. The problem is that I only want to give access to users who already have permissions over the database. This could theoretically be solved by defining Integrated Security=SSPI in the connection

问题 I have the database config show below file that reads from the application.properties which has information to connect to a single data base. I want to add another similar configuration file that will allow me to connect to another database and use its session factory like the primary one I already have. I am working on making another similar file which reads from another application properties file. However I am not sure how to wire it so that I can have multiple session factories in each of

问题 I am trying to use Hibernate when I attempt to open a Session I get the following Exception org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:656) org.springframework.web.servlet.FrameworkServlet.doPost

问题 I am simply trying to create a session factory object in hibernate 4. It throws null pointer exception while creating session factory object. Hibernate configuration file <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="connection.url">jdbc:oracle:thin:@SHKG9072DB:5030:TMSD10G2<

问题 I changed the sessionFactory bean creation in an existing application because of various reasons from : <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="mappingLocations" ref="hibernateMappingFiles" /> <property name="hibernateProperties" ref="hibernateProperties" /> </bean> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="transactionManager" class="org

问题 I am trying to create schema dynamically using hibernate / Java/ GWT, I am creating cfg.xml and hbm.xml files dynamically and storing it in database as blob. So I want to build sessionfactory for the schema. For the same I am creating configuration object using cfg.xml file, but since my hbm.xml files are in other table, they are not files on the file system, so how can I add it to configuration object as resource. I do not want to create files for them on file system . I tried addInputStream

问题 Like the title says, is there a way to "reuse" a SessionFactory for multiple databases? Since instantiating the SessionFactory takes time, I wonder if it would be possible to pool these instances and reuse them, changing only the connection/database name. Obviously, first level cache would be cleared, but I am trying to avoid the penalty involved in instantiating the factory itself. The background is that I can have several small "pluggable" databases with exactly the same schema, so there is

问题 I have created a DAO like this: This is based from: Hibernate: CRUD Generic DAO public class Dao{ SessionFactory sessionFactory; // initialise session factory public User save(User o){ return (User) sessionFactory.getCurrentSession().save(o); } public User get(Long id){ return (User) sessionFactory.getCurrentSession().get(User.class, id); } public User void saveOrUpdate(User o){ sessionFactory.getCurrentSession().saveOrUpdate(o); } Now, this is all fine, if my sessionFactory is in the DAO or
