是否可以根据错误状态代码在spring retry(https://github.com/spring-projects/spring-retry)中设置RetryPolicy ？例如我要重试上HttpServerErrorException与HttpStatus.INTERNAL_SERVER_ERROR状态码,其是503因此,应忽略所有其他错误代码- [500 - 502]和[504 - 511].

这是我在hibernate.cfg.xml中的内容

<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>

另外,我动态地覆盖了一些属性......

 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,我收到此错误...

ERROR: No suitable driver found for postgres://*******:*********@ec2-23-21-85-197.compute-1.amazonaws.com:5432/d9i5vp******o7te

如何配置我的属性以便heroku找到postgres驱动程序？

(我是hibernate和heroku的新手,所以任何帮助都非常感谢:)
