服务器启动时 No bean named 'sessionFactory' is defined

ApplicationContext ac = WebApplicationContextUtils.getWebApplicationContext(event.getServletContext()); 每一次调用这个就会使hibernate建立一个连接池, 在applicationContext-hibernate.xml中有数据库连接信息,数据库表映射信息(sessionfactory)和hibernateProperties 但是如果通过这种方式获取,写成单独的 ApplicationContext ac = new FileSystemXmlApplicationContext(path); path是applicationContext-xxx.xml 不包括applicationContext-hibernate.xml的内容 就会报出 No bean named 'sessionFactory' is defined错误

Hibernate4创建SessionFactory时卡住不运行?

Hibernate4创建SessionFactory时卡住不运行? 使用Hibernate4写一个CRUD示例,javase程序,在main方法中创建sessionFactory,使用如下代码: private HibernateUtils() { try { if (this.sessionFactory == null) { Configuration cfg = new Configuration(); cfg.configure(new File("hibernate.cfg.xml")); cfg.setNamingStrategy(ImprovedNamingStrategy.INSTANCE); ServiceRegistry sr =new ServiceRegistryBuilder().applySettings(cfg.getProperties()).buildServiceRegistry(); this.sessionFactory = cfg.addAnnotatedClass(ApplyInfo.class) .addAnnotatedClass(Contract.class) .addAnnotatedClass(Overview.class) .addAnnotatedClass(SegmentHtml.class) .buildSessionFactory(sr); } } catch (Exception e) { e.printStackTrace(); throw e; } } 在Eclipse中普通运行就会卡住不允许,如果是debug方式运行,就没有任何问题. 卡在如下日志处 五月 13, 2014 10:34:16 上午 org.hibernate.annotations.common.Version <clinit> INFO: HCANN000001: Hibernate Commons Annotations {4.0.2.Final} 五月 13, 2014 10:34:16 上午 org.hibernate.Version logVersion INFO: HHH000412: Hibernate Core {4.2.12.Final} 五月 13, 2014 10:34:16 上午 org.hibernate.cfg.Environment <clinit> INFO: HHH000206: hibernate.properties not found 五月 13, 2014 10:34:16 上午 org.hibernate.cfg.Environment buildBytecodeProvider INFO: HHH000021: Bytecode provider name : javassist 五月 13, 2014 10:34:16 上午 org.hibernate.cfg.Configuration configure INFO: HHH000042: Configuring from file: hibernate.cfg.xml 五月 13, 2014 10:34:17 上午 org.hibernate.cfg.Configuration doConfigure INFO: HHH000041: Configured SessionFactory: null 五月 13, 2014 10:34:17 上午 org.hibernate.service.jdbc.connections.internal.ConnectionProviderInitiator getConfiguredConnectionProviderName WARN: HHH000208: org.hibernate.connection.C3P0ConnectionProvider has been deprecated in favor of org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider; that provider will be used instead. 五月 13, 2014 10:34:17 上午 org.hibernate.service.jdbc.connections.internal.ConnectionProviderInitiator instantiateExplicitConnectionProvider INFO: HHH000130: Instantiating explicit connection provider: org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider 五月 13, 2014 10:34:17 上午 org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider configure INFO: HHH010002: C3P0 using driver: com.mysql.jdbc.Driver at URL: jdbc:mysql://localhost:3306/pgdata 五月 13, 2014 10:34:17 上午 org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider configure INFO: HHH000046: Connection properties: {user=root, password=****} 五月 13, 2014 10:34:17 上午 org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider configure 这句 org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider configure​ 到这里就不在向下执行.在Debug模式就没有任何问题,创建SessionFactory和Crud都正常. 数据库驱动,hibernate4小版本号够尝试换成别的版本,都没能解决问题. 请大家指教!谢谢
