当我运行来自 Groovy[Soapui] 的以下数据库连接脚本时没有响应

Question

我正在尝试从 Groovy[soapUI] 运行这个脚本，但我没有收到错误，而且 sql 命令没有返回任何结果。我在这里遗漏了什么重要的东西吗？

import groovy.sql.Sql
import java.sql.*
import com.jcraft.jsch.JSch
import com.jcraft.jsch.Session


// ssh login
String sshHost = 'test.com'
String sshUser = 'test'
String sshPass = 'test'
int sshPort = 22

// database login
targetHost = 'localhost'
targetUser = 'test'
targetPass = 'test'
targetPort = 3306
lport = 4328

JSch jsch = new JSch();
Session session = jsch.getSession(sshUser, sshHost, sshPort);
session.setPassword(sshPass);
session.setConfig("StrictHostKeyChecking", "no");
System.out.println("Establishing Connection...");
session.connect();
int assinged_port=session.setPortForwardingL(lport, targetHost, targetPort);

Connection con = null;
String driver = "org.mariadb.jdbc.Driver";
String connectionString = "jdbc:mariadb://" + targetHost +":" + lport + "/";
con = DriverManager.getConnection(connectionString, targetUser, targetPass);
Statement st = con.createStatement();
String sql = "select * from SS_System.tblcompanies where companyid=495555"
st.executeQuery(sql);
st.close()
session.disconnect()

此外，在添加一堆 log.info 语句后，我得到以下响应：

Answer 1

也许你应该对查询结果做点什么

// instead of this 
st.executeQuery(sql)

// do something like
java.sql.ResultSet rs = st.executeQuery(query);

然后按照此处所述迭代结果 https://docs.oracle.com/javase/tutorial/jdbc/basics/processingsqlstatements.html#processing_resultset_objects

while (rs.next()) {
    String value = rs.getString("COLUMN_NAME");
    log.info("COLUMN_NAME:"+value)
}
