没有去找有没有简便地方法建立测试数据,我采取自己熟练的方式去生成数据:
首先是建表:
CREATE TABLE `tb_user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(255) NOT NULL, `status` tinyint(4) NOT NULL DEFAULT '0', `password` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) )
代码:
DBUtil.java
package com.loger.utils; import java.sql.Connection; import java.sql.DriverManager; public class DbUtil { private String dbUrl="jdbc:mysql://120.79.246.xx:3306/db_test"; private String dbUserName="xxxx"; private String dbPassword="xxxxxxx"; private String jdbcName="com.mysql.jdbc.Driver"; /** * 获取数据库连接 * @return * @throws Exception */ public Connection getCon() throws Exception{ Class.forName(jdbcName); Connection con=DriverManager.getConnection(dbUrl,dbUserName,dbPassword); return con; } /** * 关闭数据库连接 * @param con * @throws Exception */ public void closeCon(Connection con) throws Exception{ if(con!=null){ con.close(); } } public static void main(String[] args) { DbUtil dbUtil=new DbUtil(); try { dbUtil.getCon(); System.out.println("数据库连接成功"); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
UUIDUtils.java
package com.loger.utils; import java.util.UUID; /** * @author Loger * Date: 2018-07-14 * TIme: 18:28 * Description : */ public class UUIDUtils { public static String getUUID(){ return UUID.randomUUID().toString().replace("-",""); } }
Main.java
package com.loger.main; import com.loger.utils.DbUtil; import com.loger.utils.UUIDUtils; import java.sql.Connection; import java.sql.Statement; import java.util.Random; /** * @author Loger * Date: 2018-08-10 * TIme: 13:57 * Description : */ public class Main { public static void main(String[] args) throws Exception { DbUtil dbUtil = new DbUtil(); Connection con = dbUtil.getCon(); Statement statement = con.createStatement(); for (int j=0;j<1000;j++){ String sql = "INSERT INTO `db_test`.`tb_user` (`id`, `name`, `status`, `password`) VALUES "; String sql2 = ""; for (int i = 0; i < 10000; i++) { sql2 = sql2 + "(null, '"+ UUIDUtils.getUUID()+"', "+(i%10)+", '0098asafpklelld,skkke1111//.asf///'),"; } sql2 = sql2 + "(null, '878999', '7', '0098asafpklelld,skkke1111//.asf///');"; sql = sql + sql2; statement.execute(sql); } con.close(); } }
这里采取的是拼接sql,然后批量提交。
运行,然后吃把鸡吧。
