我的代码如下：

import java.sql.*;

public class TestSQLServer2 {

public static void main(String[] args) {

   Connection ct = null;
   Statement sm = null;
   ResultSet rs = null;
   try {
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    ct = DriverManager.getConnection("jdbc:sqlserver://localhost;database=bbs;","sa","62280789");
    sm = ct.createStatement();
    rs = sm.executeQuery("select * from stu");
    while(rs.next()) {
     System.out.println(rs.getString(1));
    }
   }catch (Exception e) {
    e.printStackTrace();
   }finally {
    try {
     if(rs != null) {
      rs.close();
      rs = null;
     }
     if(sm != null) {
      sm.close();
      sm = null;
     }
     if(ct != null) {
      ct.close();
      ct = null;
     }
    }catch (Exception e) {
     e.printStackTrace();
    }
   }
}
}
