我正在使用Java 8，Hibernate 5.1并且在使用java代码时eclipse正常工作但是当我在java代码中设置代理或在eclipse中作为VM参数传递以连接AWS Cloud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
异常

由于代理设置或-Djava.net.useSystemProxies=true或因为云而失败？
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;
}
}
我无法为此找到根本原因。
