我升级到 hibernate4.3.11 我也在我的项目中使用 spring.4.0。

我正在通过扩展 localsessionfactorybean 方法 buildsessionfactorymethod 来加载会话工厂和映射资源。

    @Override
        protected  SessionFactory buildSessionFactory(LocalSessionFactoryBuilder localSessionFactoryBuilder){
            SessionFactory sessionFactory = null;
            PMLDialectMappings dialectMappings = null;
             String[] mappingResources = null;
            try {

                Configuration configuration = new Configuration();
                            // building mappingLocations

    Configuration configuration = new Configuration();
                            // building mappingLocations
                 dialectMappings =
                        dialectMappingsLocator.locateDialectMappings(configuration);
                if (dialectMappings != null) {
                    setMappingResources(dialectMappings.getAllMappingResources());
                    AbstractDao.setDialectSettings(dialectMappings);
                }

        ServiceRegistry  builder =  new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
                sessionFactory = configuration.buildSessionFactory(builder);

    String schema = configuration.getProperty("hibernate.default_schema");


            return super.buildSessionFactory(localSessionFactoryBuilder);
}

上面的代码创建会话工厂是否正确？我看到了上面创建会话工厂的方法，并且我正在以相同的方法加载映射资源。这是正确的还是不正确的？之前在 hibernate3 中，我们也在 getconfiguration 方法中加载映射资源。这在 Hibernate4 中已被弃用，所以我想只在 buildSessionFactory 方法中加载映射资源。

同样在谷歌中，如果您在属性下方添加“无休眠会话”错误将会消失，但它对我不起作用。所以请提出其他建议。

hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

hibernate 3中的代码是构建sessionfactory和加载mappingresource

@Override
    protected SessionFactory newSessionFactory(Configuration config) {
        try {
            String schema = config.getProperty("hibernate.default_schema");
            if (schema != null && schema.length() > 0) {
                AbstractDao.setSchemaName(schema);
            } else {
                Logger.get(Constants.PML_LOGGER).warning(
                    "Property 'hibernate.default_schema' not set: using default");
            }
        } catch (Throwable t) {
            Logger.get(Constants.PML_LOGGER).exception(LogType.CRITICAL, null, null,
                "PMLSessionFactoryBean: newSessionFactory method failed", t);
            throw new HibernateException(t.getMessage());
        }
        return super.newSessionFactory(config);
    }

    /**
     * @return Configuration
     * @see org.springframework.orm.hibernate3.LocalSessionFactoryBean#newConfiguration()
     */
    @Override
    protected Configuration newConfiguration() {
        Configuration configuration = super.newConfiguration();
        // building mappingLocations
        PMLDialectMappings dialectMappings =
            dialectMappingsLocator.locateDialectMappings(configuration);
        if (dialectMappings != null) {
            setMappingResources(dialectMappings.getAllMappingResources());
            AbstractDao.setDialectSettings(dialectMappings);
        }
        return configuration;
    }

}

主要是我需要知道如何创建sessionfactory和如何加载mappingresources。

更改了我的localsessionfactorybean代码，如下所示。然后正确加载所有映射资源。hibernate 3 配置中的先前配置是在加载之前加载所有映射sessionfactorybean。但是在hiberate4中不是这样的，你必须手动将资源添加到localsessionfactorybean中。我添加的同样的东西它的工作。我认为setmappingresources负载足够了，但你也需要addresourcebean localsessionfactory。

dialectMappings = dialectMappingsLocator.locateDialectMappings(configuration);

if (dialectMappings != null) {
    setMappingResources(dialectMappings.getAllMappingResources());
    AbstractDao.setDialectSettings(dialectMappings);
}

for(String resource : dialectMappings.getParentDialectMappings().getAllMappingResources()) {
    configuration.addResource(resource);
}

之后我实施了适当的实施nullsafeget，nullsafeset现在我们的项目已完全升级到休眠 4.3.11。最后，我们能够为我的所有查询添加查询提示，这有助于强制对表进行索引。感谢 stackoverflow 的帮助。
