Java使用Mysql数据库实现批量添加数据

EmployeeDao.java

//批处理添加数据

public int saveEmploeeBatch(){

int row = 0;

try{

con = DBCon.getConn();

String sql = "insert into tb_employee(name,age,sex,duty)values(?,?,?,?)";

pstmt = (PreparedStatement) con.prepareStatement(sql);

Random random = new Random();

for(int i = 0; i < 10; i++){

pstmt.setString(1 , "22"+i);

pstmt.setInt(2, 1+i);

pstmt.setString(3, i % 2 == 0?"男":"女");

pstmt.setInt(4, random.nextInt(5)+10);

pstmt.addBatch();

}

int[] rows = pstmt.executeBatch();

row = rows.length;

}catch(Exception e){

e.printStackTrace();

}finally{

try{

if(pstmt != null)

pstmt.close();

}catch(Exception e){

e.printStackTrace();

}

try{

if(con != null)

con.close();

}catch(Exception e){

e.printStackTrace();

}

}

return row;

}

 

TestSql05.java

package com.sql.test;

 

import com.sql.dao.EmployeeDao;

 

public class TestSql05 {

 

public static void main(String[] args){

int rows = EmployeeDao.getInstance().saveEmploeeBatch();

System.out.println("批量添加信息的行数是:"+rows);

}

}
