Question

我正在使用基于模式的多租户，为MultiTenantConnectionProvider＆amp; CurrentTenantIdentifierResolver。尝试为单个租户获得休眠会话会因NPE而失败。查看hibernate的源代码，似乎JDBCServicesImpl在else块中将connectionProvider初始化为null

private JdbcConnectionAccess buildJdbcConnectionAccess(Map configValues) {
    final MultiTenancyStrategy multiTenancyStrategy = MultiTenancyStrategy.determineMultiTenancyStrategy( configValues );

    if ( MultiTenancyStrategy.NONE == multiTenancyStrategy ) {
        connectionProvider = serviceRegistry.getService( ConnectionProvider.class );
        return new ConnectionProviderJdbcConnectionAccess( connectionProvider );
    }
    else {
        connectionProvider = null;
        final MultiTenantConnectionProvider multiTenantConnectionProvider = serviceRegistry.getService( MultiTenantConnectionProvider.class );
        return new MultiTenantConnectionProviderJdbcConnectionAccess( multiTenantConnectionProvider );
    }
}

请在此处找到此测试用例 - http://pastebin.com/7Mt9wtHt及其堆栈跟踪 - http://pastebin.com/8ygAu7eh

我错过了一些基本的东西吗？

我也面临同样的问题。当我用Google搜索时，在hibernate中发布了一个错误。这是链接https://hibernate.atlassian.net/browse/HHH-7395
