 开发四年只会写业务代码，分布式高并发都不会还做程序员？->>>    代码如下：      import java.sql.*; public class ShowSql { public static void main(String[] args) { String url = "jdbc:sqlserver://localhost:1433;DatabaseName=hah"; Connection conn=null; Statement st = null; ResultSet rs = null; try { Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); System.out.println("loading success!"); conn = DriverManager.getConnection(url,"sa","admin"); System.out.println("conn success!"); st = conn.createStatement(); rs=st.executeQuery("select top 10 * from Group2"); while(rs.next()){ System.out.println(rs.getString("name")); } } catch (ClassNotFoundException e) { e.printStackTrace(); } catch (SQLException e) { e.printStackTrace(); } } } 报错如下：      "C:\Program Files\Java\jdk-9.0.1\bin\java" "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2017.2.5\lib\idea_rt.jar=11045:C:\Program Files\JetBrains\IntelliJ IDEA 2017.2.5\bin" -Dfile.encoding=UTF-8 -classpath "D:\Iproject\TestWeb\web\WEB-INF\classes;D:\JAVA\apache-tomcat-9.0.2\lib\servlet-api.jar;E:\SQL\jdbc\Microsoft JDBC Driver 6.0 for SQL Server\sqljdbc_6.0\chs\jre8\sqljdbc42.jar" ShowSql loading success!
