【问题描述】*：采用docker部署的达梦V8数据库，查看日志启动也都正常，容器内也能连接到数据库，但是宿主机却无法连接：
root@hj-pc:~# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

本地通过telnet也能连接25236，但是通过jdbc就连接不了，报错：

驱动使用的是：
<dependency>
<groupId>com.dameng</groupId>
<artifactId>DmJdbcDriver18</artifactId>
<version>8.1.3.140</version>
</dependency>
测试代码：
public class DMJdbcConnTest {

// 定义连接
static Connection con = null;
// 定义 DM JDBC 驱动串
static String cname = "dm.jdbc.driver.DmDriver";
// 定义 DM URL 连接串
static String url = "jdbc:dm://localhost:25236";
// 定义连接用户名
static String userid = "SYSDBA";
// 定义连接用户口令
static String pwd = "SYSDBA_dm001";
public static void main(String[] args) {
try {
Class.forName(cname);
con = DriverManager.getConnection(url, userid, pwd);
con.setAutoCommit(true);
System.out.println("[SUCCESS]conn database");
} catch (Exception e) {
e.printStackTrace();
System.out.println("[FAIL]conn database：" + e.getMessage());
}
}
public void disConn(Connection con) throws SQLException {
if (con != null) {
con.close();
}
}
