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

我正在加载会话工厂并通过扩展localsessionfactorybean方法buildsessionfactory方法来映射资源。

    @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);
}

以上代码是否正确创建sessionfactory？我在上面看到了创建会话工厂的方法，我在同一个方法中加载mappingresources。这是正确与否？以前在hibernate3中我们也在getconfiguration方法中加载映射资源。在Hibernate4中不推荐使用，所以我想只在buildSessionFactory方法中加载mappingresources。

同样在谷歌我觉得如果你添加下面的属性'没有hibernate会话'错误将去，但它不适合我。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load 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;
    }

}

Hibernate 4更改了缓存regionfactory并将transanctionmanager更改为hibernate 4。

主要是我需要如何创建sessionfactory以及如何加载mappingresources。

1 个答案:

答案 0 :(得分：0)

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配置中的前一个配置是在加载sessionfactorybean之前加载所有映射。但是在hiberate4不是那样的，你必须手动将资源添加到localsessionfactory bean。同样的事情我添加了它的工作。我认为setmappingresources足以加载，但您也需要addresource到localsessionfactory bean。

dialectMappings = dialectMappingsLocator.locateDialectMappings(configuration);

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

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

之后我实现了正确的nullsafeget和nullsafeset实现，现在我们的项目完全升级到hibernate 4.3.11。最后，我们可以向所有查询添加查询提示，以帮助强制索引表。感谢stackoverflow的帮助。
