以下是我在hibernate.cfg.xml中的配置:
<hibernate-configuration>
<session-factory>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</property>
<property name="hibernate.connection.charSet">UTF-8</property>
<property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
<property name="connection.driver_class">org.postgresql.Driver</property>
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="connection.pool_size">1</property>
<property name="show_sql">true</property>
<property name="hibernate.use_outer_join">true</property>
<property name="current_session_context_class">thread</property>
</session-factory>
</hibernate-configuration>
此外,我正在动态地覆盖一些属性...
Configuration config = new Configuration().configure("path_to_hibernate.cfg.xml");
config.setProperty("hibernate.connection.url", System.getenv("HEROKU_POSTGRESQL_MYCOLOR_URL"));
config.setProperty("hibernate.connection.username", "***");
config.setProperty("hibernate.connection.password", "***");
但是,当我运行它时,我遇到了这个错误...
ERROR: No suitable driver found for postgres://*******:*********@ec2-23-21-85-197.compute-1.amazonaws.com:5432/d9i5vp******o7te
我该如何配置属性,让heroku找到postgres驱动程序?
(我是hibernate和heroku的新手,希望得到您的帮助 :)
