如何配置intellij idea使用hibernate持久化工具和从外部jar文件读取映射文件

Question

假设我在hibernate.cfg.xml 文件下面有这个包含数据源配置和包含.hbm.xml 映射的jar 文件的路径：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">oracle.jdbc.OracleDriver</property>
        <property name="hibernate.connection.url">jdbc:oracle:thin:@192.168.251.134:1521:DB</property>
        <property name="hibernate.connection.username">rgh</property>
        <property name="hibernate.connection.password">rgh</property>
        <property name="hibernate.connection.pool_size">10</property>
        <property name="show_sql">true</property>
        <property name="hibernate.connection.internal_logon">normal</property>
        <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>
        <property name="hibernate.hbm2ddl.auto">none</property>
        <property name="hibernate.default_schema">rgh</property>
        <property name="hibernate.connection.datasource">jndi</property>
        <!-- Mapping files -->

        <mapping jar="C:\Users\Ghafari\.m2\repository\org\rgh\goodsCirculation\1.0-releases\goods-1.0-releases.jar"></mapping>
        <mapping jar="C:\Users\Ghafari\.m2\repository\org\rgh\core\1.0-releases\core-1.0-releases.jar"></mapping>
        <mapping jar="C:\Users\Ghafari\.m2\repository\org\rgh\framework\2.1.1-releases\framework-2.1.1-releases.jar"></mapping>
    </session-factory>
</hibernate-configuration>

我应该如何配置 intellij idea 以使用休眠控制台并编写 hql 查询？ 每个jar文件只包含.hbm.xml文件

更新

我不能把每个映射都像<mapping resource="org/rgh/hibernate/Category.hbm.xml"/> 这样，因为我有超过 1,500 个.hbm.xml 文件。

更新

我最近从 Eclipse 迁移到 Intellij Idea，在 Eclipse hql 编辑器工具中可以正常使用这个 hibernate.cfg.xml 文件，但 Intellij Idea 不起作用。

您可以使用 LocalSessionFactoryBean 的 setMappingJarLocations 方法来加载 jar 位置的类。示例如下：

public static SessionFactory buildSessionFactory(DatabaseData dbData) {
    SessionFactory sessionFactory = null;
    try {

        if (dbData != null) {
            // logger.info("dbData not null");
            // logger.info("dbData driver : "+dbData.getDataSourceDriver());
            // logger.info("dbData IP : "+dbData.getDatabaseIP());
            logger.info("dbData  DBNAme : " + dbData.getDatabaseSchema());
            // logger.info("dbData Uname "+dbData.getDatabaseUserName() +"
            // pwd :
            // "+dbData.getDatabaseUserName());

            DriverManagerDataSource dataSource = new DriverManagerDataSource();
            dataSource.setDriverClassName(dbData.getDataSourceDriver());
            dataSource.setUrl("jdbc:mysql://" + dbData.getDatabaseIP() + ":" + dbData.getDatabasePort() + "/" + dbData.getDatabaseSchema()
                    + "?autoReconnect=true&useSSL=false");
            dataSource.setUsername(dbData.getDatabaseUserName());
            dataSource.setPassword(dbData.getDatabasePassword());

            LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
            sessionFactoryBean.setDataSource(dataSource);

            Properties hibernateProperties = new Properties();
            // hibernateProperties.put("hibernate.dialect",
            // HIBERNATE_DIALECT);
            hibernateProperties.put("hibernate.show_sql", false);
            //hibernateProperties.put("hibernate.hbm2ddl.auto", "update");
            sessionFactoryBean.setHibernateProperties(hibernateProperties);

// load the entity classes from a package
//sessionFactoryBean.setPackagesToScan("com.**.**.entity");
//load the entity classes from jar
sessionFactoryBean.setMappingJarLocations("location for jar file");
                sessionFactoryBean.afterPropertiesSet();
                return sessionFactoryBean.getObject();
            }
        } catch (Exception ex) {
            logger.error("Initial SessionFactory creation failed.", ex);
            ex.printStackTrace();
            throw new ExceptionInInitializerError(ex);
        }
        return sessionFactory;
    }

DatabaseData 类包含 db url、用户名和密码等：

public class DatabaseData {

private String databaseIP;
private String databasePort;
private String databaseName;
private String databaseSchema;
private String databaseUserName;
private String databasePassword;
private String dataSourceDriver;
private int timeout;
}
