实现Java批量插入数据库数据：
package Proxy;import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStreamReader;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;public class TextReader{public static void main(String args[]) { try{Class.forName("com.mysql.jdbc.Driver"); Connection con = (Connection) DriverManager.getConnection("jdbc:mysql://" + "localhost:3306/DP", "admin", "123456"); String sql = "Insert into ACT_cdKeytempsss (cdKey, ActivityId) VALUES (?,3577)";String sqlupdate = "update ACT_cdKey set status=1 where CdKey = ?";PreparedStatement ps = con.prepareStatement(sql);PreparedStatement ps1 = con.prepareStatement(sqlupdate);con.setAutoCommit(false); // 关闭事务自动提交 String pathname = "C:/Users/Administrator/Desktop/result8.txt";File fileName = new File(pathname);InputStreamReader reader = new InputStreamReader(new FileInputStream(fileName));BufferedReader br = new BufferedReader(reader); String line = ""; line = br.readLine(); while (line != null) { ps.setString(1, line);ps1.setString(1, line);line = br.readLine();ps.addBatch();ps1.addBatch();} ps.executeBatch();ps1.executeBatch();con.commit();ps.close();ps1.close();con.close();br.close();}catch (Exception e) {e.printStackTrace();// TODO: handle exception}}
} 
)
