Eclipse org.hibernate.service.spi.ServiceException:无法创建请求的服务[org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

我使用的是Java 8、Hibernate 5.1和eclipse，使用Java代码时工作正常，但当我在Java代码中设置代理或在eclipse中作为VM参数传递以连接AWS云时，Hibernate连接失败。 我设置代理的Java代码

System.setProperty("java.net.useSystemProxies", "true");
System.setProperty("http.proxyHost", "comproxy.net");
System.setProperty("http.proxyPort", "80");
System.setProperty("http.nonProxyHosts", "localhost|127.0.0.1");
System.setProperty("http.proxyUser", "tm_user");
System.setProperty("http.proxyPassword", "password@135");    

或VM参数

-Djava.net.useSystemProxies=true
-Dhttp.proxyHost=comproxy.is
-Dhttp.proxyPort=80
-Dhttp.nonProxyHosts=localhost
-Dhttp.proxyUser=tm_user
-Dhttp.proxyPassword=pwd@135

例外情况

我无法找到此问题的根本原因。

请检查代理服务器的主机名和端口。即使在你的问题中，你也使用了两个不同的主机名。嗨@Holger，谢谢你的回复，因为它的类型错误，两个主机都是相同的。我使用Hibernate5.1连接DB，在使用HttpURLConnection获取AWS云上的记录发布数据后，问题是一次只发生一个连接。例如，如果我用hibernate连接DB，那么AWS连接失败如果我首先连接AWS，那么我将获得堆栈跟踪以上，在从DB连接跳到AWS或AWS跳到DB之前，我总是启动新连接并关闭所有会话。可能是代理限制？有趣的是：如果详细说明，会有助于了解更多。即使在今天，我仍在尝试使用JDBC，并得到错误

java.sql.SQLException:Io exception:Network Adapter无法建立连接

我感觉有些资源被一种连接占用，而没有释放用于另一种连接。嗯，最大连接数可以设置为1。

public class HibernateUtil {

  private final static SessionFactory sessionFactory;
  //private static final SessionFactory sessionFactory = buildSessionFactory();

  static{
    try {   
      sessionFactory = new Configuration().configure("/com/singtel/mi/utils/hibernate.cfg.xml").buildSessionFactory();

    } catch (Exception e) {
      System.err.println("Seesion Factory Creation Failed---> "+e);
      throw new ExceptionInInitializerError();
    }
  }

  public static SessionFactory getSessionFactory(){
    return sessionFactory;
  }
}
