網(wǎng)上的資料真爛，千篇一律的拷貝的，根本不能用，鄙視！ 正題： 到MYSQL網(wǎng)站下載mysql-connector-java-5.0.4.zip文件，解壓； 解壓后有一個(gè)文件：mysql-connector-java-5.0.4-bin.jar 把這個(gè)文件放到應(yīng)用的lib包里或者寫一個(gè)classpath確定絕對(duì)地址。 package org.sytuyuan; import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; import java.sql.Statement; import java.sql.ResultSet; public class MySqlTest { ??? public static void main(String[] args) { ??? ??? try { ??? ??? ??? Class.forName("com.mysql.jdbc.Driver"); ??? ??? ??? Connection con = DriverManager.getConnection( ??? ??? ??? ??? ??? "jdbc:mysql://localhost/test", "root", "123456"); ??? ??? ??? Statement stmt = con.createStatement(); ??? ??? ??? // stmt.execute("insert into user values('123',null,null,null) "); ??? ??? ??? ResultSet rs = stmt.executeQuery("select * from user"); ??? ??? ??? while (rs.next()) { ??? ??? ??? ???
