Question

我正在尝试使用hibernate插入记录。当数据库用户名和密码与其他所有数据库一起在hibernate配置文件中时，它工作正常属性。

但是当我从配置文件中删除用户名和密码时，我无法插入。我能做错什么？

            Configuration c = new Configuration();
    c.configure();

    c.setProperty("connection.username", "abc" );
    c.setProperty("connection.password", "secret" ); 
    SessionFactory sessFact =   c.buildSessionFactory();
    Session sess = sessFact.openSession();

    Transaction tx = sess.beginTransaction();
            sess.save(inf);
    tx.commit();
    sess.close();

我想从xml配置文件中选择大多数属性，除了uid和密码。

尝试使用此代码：

    Configuration c = new Configuration();
    c.configure();

    c.setProperty("hibernate.connection.username", "abc" );
    c.setProperty("hibernate.connection.password", "secret" );

您错过了为属性名称添加hibernate前缀。

Answer 2

我想知道.setProperty之前的.configure是如何工作的。对我来说，我必须在.setProperty之后配置。我还必须在

中拨打.applySettings(configuration.getProperties())

ServiceRegistry serviceRegistry = new ServiceRegistryBuilder()    
        .applySettings(configuration.getProperties())    
        .buildServiceRegistry();

让它发挥作用。

也许因为我现在正在使用Hibernate 3.0。

xml配置后的程序化hibernate配置
