我的数据库位于ssh隧道中，我使用JSch连接它。
这是我的Java代码：
static String sshHost, sshAccount, sshPassword;
static int sshPort = 22;
static int localPort = 3399, remotePort = 3306;
static String remoteHost = "localhost";
public static void main(String[] args) throws JSchException {
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
JSch jsch = new JSch();
com.jcraft.jsch.Session jschSession = jsch.getSession(sshAccount, sshHost, sshPort);
jschSession.setPassword(sshPassword);
jschSession.setConfig(config);
System.out.println("Start Connecting " + sshHost + ":" + sshPort);
jschSession.connect();
int assinged_port = jschSession.setPortForwardingL(localPort,
remoteHost, remotePort);
System.out.println("localhost:" + assinged_port + " -> " + remoteHost + ":" + remotePort);
System.out.println("Connect Hibernate");
Configuration configuration = new Configuration().configure();
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
SessionFactory factory = configuration.buildSessionFactory(builder.build());
Session session = factory.openSession();
Transaction tx = session.beginTransaction();
System.out.println("Close Hibernate Connection");
tx.commit();
session.close();
factory.close();
System.out.println("Closing SSH Connection");
session.disconnect();
}
这是我的Hibernate.cfg.xml：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration >
<session-factory name="java:hibernate/SessionFactory">
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
</session-factory>
<mapping class="db.User" />
</hibernate-configuration>
我已经使用here和here中的代码进行测试。因此，我确定SSH服务器，数据库帐户，密码，URL和端口的变量是正确的。
运行代码后，它给出了错误消息：

我不知道如何连接我的数据库。
现在我更改xml文件，如下所示（删除会话工厂中db.User＆amp;“name”属性的映射）：
<hibernate-configuration >
<session-factory>
...
</session-factory>
</hibernate-configuration>
我也使用Question 12737293给出的方式，所以我确定我的端口（3399）没有使用。
但是，它仍然给出了错误消息：

答案 0 :(得分：-1)
您遇到此问题，因为您已将<mapping>标记保留在<session-factory>标记之外。
你hibernate.cfg.xml看起来应该是
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<property name="hibernate.connection.password">password</property>
