Java 我们可以在没有Hibernate.cfg.xml的情况下配置Hibernate吗,java,spring,hibernate,spring-mvc,Java,Spring,Hibernate,Spring Mvc,下面是hibernate.cfg.xml： <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-con

下面是

hibernate.cfg.xml

：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.DerbyDialect</property>
<property name="hibernate.connection.driver_class">org.apache.derby.jdbc.ClientDriver</property>

我想知道在每个hibernate应用程序中是否总是需要使用

hibernate.cfg.xml

，或者是否有其他方法来配置hibernate。

没有必要，在会话工厂bean配置中，您可以使用

    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.DerbyDialect</prop>
            <prop key="hibernate.show_sql"></prop>
            <prop key="hibernate.use_outer_join">true</prop>
        </props>
    </property>

您可以将hibernate.cfg.xml的属性指定为springbean.xml中的属性注入比如说

<property name="hibernateProperties">  
    <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
    </props>
    </property>


org.hibernate.dialen.oracle10galent
更新

因此，以类似的方式，您可以将spring中的所有属性指定为sessionFacory的依赖项，您可以通过使用java设置属性来实现这一点

    public class TestHibernate {

        public static void main(String arg[]) {
        Properties prop= new Properties();

        prop.setProperty("hibernate.connection.url", "jdbc:mysql://<your-host>:<your-port>/<your-dbname>");

        //You can use any database you want, I had it configured for Postgres
        prop.setProperty("dialect", "org.hibernate.dialect.PostgresSQL");

        prop.setProperty("hibernate.connection.username", "<your-user>");
        prop.setProperty("hibernate.connection.password", "<your-password>");
        prop.setProperty("hibernate.connection.driver_class", "org.postgresql.Driver");
        prop.setProperty("show_sql", true); //If you wish to see the generated sql query

    SessionFactory sessionFactory = new Configuration().addProperties(prop).buildSessionFactory();
       Session session = sessionFactory.openSession();
    session.beginTransaction();
            Customer user = new Customer(); //Note customer is a POJO maps to the customer table in the database.

    user.setName("test");
    user.setisActive(true);
    session.save(user);
    session.getTransaction().commit();
    session.close(); 

    }

    }

    public Customer() {

        this.customerid = customerId;
        this.isActive = isActive;
    }

该文件有什么问题？该文件没有问题，但我想知道是否有其他方法可以配置Hibernate。如果你想知道这没问题，但是，更喜欢使用xml文件。哪一种是最好的。最好和最简洁的答案是我必须使用“Hibernate.dial”而不是“dial”作为设置方言的关键。希望这对别人有帮助！

    public class TestHibernate {

        public static void main(String arg[]) {
        Properties prop= new Properties();

        //You can use any database you want, I had it configured for Postgres

        prop.setProperty("hibernate.connection.username", "<your-user>");
        prop.setProperty("hibernate.connection.password", "<your-password>");
        prop.setProperty("hibernate.connection.driver_class", "org.postgresql.Driver");
        prop.setProperty("show_sql", true); //If you wish to see the generated sql query

    SessionFactory sessionFactory = new Configuration().addProperties(prop).buildSessionFactory();
       Session session = sessionFactory.openSession();
    session.beginTransaction();
            Customer user = new Customer(); //Note customer is a POJO maps to the customer table in the database.

    user.setName("test");
    user.setisActive(true);
    session.save(user);
    session.getTransaction().commit();
    session.close(); 

    }

    }
